Hurricane Frances ... Florida, USA ... 4th
September 2004
Hurricane Frances was on 3rd September, still forecast
to strike Florida on the afternoon of Saturday 4th September 2004 Local time (EST = GMT -
4 hours )
Current information on Tropical
Storms World-wide:
As early as 24th August, Jim Leonard mentioned to the
Tropical Cyclones Discussion Group a tropical disturbance that had been noticed in the
Eastern Atlantic not far from Africa. By 26th August Tropical Storm Frances had been
named and was approaching hurricane strength. At this stage the storm was still
listed on my web site as "no threat to land." I changed this to "no
immediate threat to land" when the models started forecasting a possible approach
towards Bahamas and Florida about a week in advance. In a week, a tropical cyclone
can decide to do almost anything it wants, despite our best efforts at forecasting. By
28th August, I was simultaneously tracking no fewer than ten active tropical cyclones on
my page ... an all-time record! I rapidly knocked off four of them as they decayed
and changed my notation on Frances to "towards Bahamas and Florida" with orange
colouring which always denotes that this cyclone is no immediate threat to populated
areas. As the discussion and forecasts showed landfall more and more likely, I
changed the notation to red colouring which always means that this cyclone is potentially
dangerous to populated areas.
In the late evening of Friday 3rd September, I decided to commence a web page - this one -
to record al sorts of interesting facts about Frances as she approached Florida. I
shall endeavour to keep this page as up-to-date as possible during the next few days as
Frances reaches and crosses Florida. It seems that prayer is being answered as I
type on the morning of 4th September, as Frances has weakened from a powerful Category
Four Hurricane which was forecast to intensify to Category Five on Friday to a much less
powerful Category Two this morning.
As you may gather from the e-mails and forecast maps, Frances stalled just off the coast
until Sturday evening and then moved across the peninsula during Saturday night and all
day Sunday. According to TV broadcasts, insurance compamies estimated the damage
done on the peninsula to be in excess of USD$10 billion. The storm failed to fully
regain Hurricane strenght over the Gulf and was still a Tropical Storm as it crossed the
Panhandle into SW Georgia - SE Alabama area where warnings were discontinued.

I have compiled a selection of some of the e-mails in which Frances has been discussed
by experts and amateur enthusiasts alike. Sometimes you can read also about some of
the simultaneous tropical cyclones which were active during the long life of Frances.
Occasionally I have cut irrelevant or personal sections out of e-mails, denoted by

It looks like the Atlantic basin is about to get some action again soon. The disturbance
out at around 10N and 29W appears to be well on its way to become the next tropical storm
or hurricane. Conditions ahead of it look quite favorable. This could be one of those all
the way across the Atlantic type tracks we would expect this time of the season.

We shall see if this one actually makes it all the way across- the main models have been

Hi to all... Even though the GFS turns this system NW lets see if this forecast becomes a
reality because conditions seem to be more favorable for a more westerly track in the next
few days, NOGAPS seems to keep this system at a lower latitude in a track more towards the
W-WNW. Lets see how this disturbance develops and moves across the area and also there are
two or three more systems forecasted to develop after this one so a more active period
coming as typical getting to the peak of the ATL season...

Hi to all...
Tropical storm Frances is now getting closer to hurricane strenght as it moves WNW17mph
and gets closer to the islands, want to poin out that every model has been moving farther
west this system in every new run so this means they bring this cyclone closer to the
Northern Leeward Islands as time goes by, this was also pointed by Lixion Avila of NHC in
the 5am 0900Z discussion.
We'll have to watch this system closely in the Caribbean because it may turn more to the
west later in the period which could bring this system towards us as the ridge gets
stronger. The system continues to have some light easterly shear which means that high its
still pushing it in a more W track. So now that winds are estimated at 60mph they may
already be upped to 65 or 70mph in the next advisory or even upgraded to hurricane
strenght lets see how this difference in the forecast models ends...
Stay tuned

Date: 08/26/2004 22:26 Subject: TS Frances nearing hurricane strenght
hi to all...
Tropical storm Frances is now nearing hurricane strenght and it has now moved more
westward in the past hours and is developing an eye as it continues in rather favorable
conditions for intensification. The models continue to be in no agreement about the future
track of this storm so still the islands have a great chance to be hitted by this
hurricane as it is now a classic Cape Verde track. Lixion Avila pointed out this
posibility in the 5am 0900Z discussion about Frances. So weŽll have to watch this very
carefully in the islands as TS Frances is about to become a hurricaneas it continues in
that westward track...

That's the understatement of the year!!!!!!
As of right now, there've been 19 NS (counting TS-21W) in the NH since Alex was named on 1
August. I'm pretty sure that's a record number of NS in any month since I started writing
the TC summaries almost 7 yrs ago.
Gaston is the 7th Atlantic NS for August, tying 1933 and 1995, and an 8th one is certainly
not out of the question as the LOW east of Gaston slowly becomes better organized.

Really interesting to speculate on just what Frances might do. If it does impact S
Fla as the models are suggesting, and nothing happens to weaken it, Frances could turn out
to be one of the truly great historical S Fla hurricanes on the order of 1926, 1928, Donna
or Andrew.
Another thing which is very interesting is the pattern of WestPac activity lately, with
the primary area of formation shifting east to the Marshall Islands. This is more typical
of El Nino years.
Wonder if that's a harbinger of an El Nino coming soon????

If the disturbance S of Bermuda becomes a named storm before the end of the month, we will
tie the record for the most number of named storms (8) to form in one month in the
Atlantic basin. The record of 8 was just set only 2 years ago in Sept!
With Charley's impact still fresh in everyone's mind, I can see the media hype for Frances
going through the roof, especially if Florida ends up being the target.

I thought nobody cares about Gaston until I received this.
Strange. I couldn't see any headline about Gaston at CNN, Foxnews and etc. Will it pose
any threat when it makes landfall in South Carolina? Or, it is simply because the media
turn the focus on olympic, especially the "Dream Team" and the disappointing

For the 1926 Miami hurricane, if I remember correctly, adjusted for inflation and the
build up over the decades in the Miami area, the damage in 2000 dollars for the same
hurricane would be on the order of nearly 90 billion dollars. That just boggles the mind.

Hi Bussie and all,
Check out the Northern Hemisphere for Tropical Cyclones.
Yesterday I was tracking ten storms simultaneously on my page at http://www.drdisk.com.hk/cyclones.htm but
I have dropped off three storms yesterday when they got below 25 Knots and another one
today, so now I only have six on the page.
We have had 16 or 17 named storms for August so far, maybe more ... I haven't kept count
that carefully - too busy typing up all the HTML.
The current ukmet model shows Hurricane Frances making a direct hit on Miami late this
week, then passing just North of Naples and then making a direct hit on Tampa after
recurving over the Gulf.
Typhoon Chaba, nearing Kyushu, Japan, has an eye of 100 NM and 50 Knot winds out to 300 NM
radius in all directions. Its outer rainbands are currently covering South Korea, Kyushu,
Shikoku, almost all of Honshu, Taiwan, Okinawa, Ryukyu Is, and NE Philippines. The total
storm is thus well over 1200 km in diameter maybe over 2000 km. Talk of shades of
"The Day After Tomorrow"!
Meanwhile here in Hong Kong we have Tropical Depression AERE (ex-20W) sitting directly
over us and emptying the heavens upon us. Nearly got drowned going to Church this morning.
So far today the observatory here has hoisted Thunderstorm Warnings, Rainstorm Warnings,
Flooding Warnings and Landslip Warnings.
The river outside my window looks like milk coffee because of all the soil being washed
down. Check http://www.hko.gov.hk/wxinfo/rainfall/isohyet_p24e.shtml

Well, I'm just firing up systems here for Tropical Storm Gaston, and we're all keeping an

Lets hope not Tony.
I've been tracking Frances since early development and with it's current intensity, if it
makes landfall, there is going to be some major destruction. Already rated as a Category 4
hurricane, Frances is looking at even becoming a Category 5 over the next few days.
Talking with fellow US chasers, we are looking at Frances possibly turning more to the NW
after it crosses the Bermuda area and heading up the coast towards Northern Florida, but
that is still too early at this stage to know. But a majority agreed that if this
happened, that SC would probably bear the brunt of a landfall.
For those that are wondering what is happening, I've uploaded a screen capture from my
hurricane tracking software at HYPERLINK http://www.lexicon.net/yolestorm/hurricane/US.GIF

Hopefully this one will stay away from SW Fl and my fiance and son.

That's my view exactly. SST's look quite high and the path is almost entirely water, which
means conditions are ripe for intensification. The more immediate issue is Tropical Storm
Gaston. I've already activated some systems for that event, but Frances is the more
worrying one. I don't like the look of Frances, something bugging me about that storm.
Hope I'm wrong.

The models are mixed with some saying FL, others saying SC. Some of the guys on the
Skywarn Net this morning made comparisons between Frances and Andrew.

Agreed Tony.
Frances has been bugging me too, and it is a similar path to what Andrew took. I've taken
a screenshot of the similarities between Andrew's path and Frances' forecast path... Both
quite similar at the moment, although Andrew took a more northerly bend than Frances is
forecast too, but it wouldn't take too much to bend out west and make a dash for Miami and
Southern Florida again.
The screenshot is at HYPERLINK http://www.lexicon.net/yolestorm/hurricane/AndrewFrances.GIF
Fortunately Gaston isn't going to be a major hurricane, but with the advent of Charley not
too long ago, the area is still suffering Charley's after effects. Some major flooding
could well follow.
Hopefully Gaston remains below Category 1 levels, although the forecast is for it to make
the bare minimums for a Cat 1.

I know you saw Rich's reply, but this is to the rest of our group: (not sure if the
'estimated' surface winds of 65kts will have any bearing on the final
determination--unless someone does a storm damage review along the coast at the exact
landfall location):
Hi Roger,
Greetings from St Croix. We have a full deployment to St Croix (and then some) for
Frances...the full court press when it comes to recon.
On our way from Keesler yesterday we delayed six hours off the South Carolina coast and
did four fixes on Gaston. Considering it was hardly on anyone's list Friday morning, it
had a very interesting 48 hour life as a TC. I have attached three files, one is the raw
obs file for the mission, the other two are just HDOBS, including an excel spreadsheet of
our HBOBS while down at low level in the storm. If you plot up the data you will see a
very good sampling of the thermodynamic environment of a vigorous TS down at 300 meters
For Dr Molinari: John, the dew point hygrometer was working very well yesterday and I
think we saw another example of how a great deal of thermodynamic energy was accumulating
in the core of Gaston.
At 300 meters we had a strong upward spike in both the eye temp and eye dew point on each
of our four passes through the center. With an eye temp of over 26C and eye dew points as
high as 25.2C, the theta e values in the core were very high. On our final fix we actually
would have loved to have released two sondes, as silly as that may seem from 300 meters,
the first to confirm the 65 knot surface winds we clearly saw for about two minutes just
prior to the fix (with FL winds still holding at less than 60 knots), and then in the eye,
to get a better feel for just how warm the boundary layer below us really was.
Unfortunately, the GPS sondes drop at about 1000 meters per minute so we would not have
gotten more than about 20 seconds of good data before it splashed. IMHO, it would have
been well worthwhile in this case, but I am not sure how the Air Force would have viewed
it (and at $500+ apiece it may have been a painful salary deduction).
The effort being mounted to study Frances is really noteworthy. We not only have the
regular recon fix missions but also buoy drop missions and high altitude synoptic
surveillance tracks. NOAA is flying the P3s on both CBLAST and low-level SFMR missions
along with the G-IV doing more synoptic tracks. Gaston was something of a victim of
aircraft availability. TD#8, which has probably already formed by now and might even be
Hermine already, will also be difficult to fly with all the Frances stuff going on.
If that were not enough, last night we just happened to fly right through the center of a
cold core TUTT cell northwest of Puerto Rico (with about a 3 to 4 degree temp drop in the
core at our FL of 25,000 feet) on our way to St Croix from Gaston. I notice today that
there is a persistent batch of convection associated with this feature. Who knows...maybe
we will have yet another system to watch if it undergoes a transition.
For anyone in St Croix over the next few days, I am at the Buccaneer if you want to get
together and have lunch......Rich

It has peaked for now, and NHC has backed off on the intensity forecast- keeping it at 110
kts thru the period. The track models have mostly converged on a farther north scenario-
including the 00Z GFS- which has the data from a NOAA plane that got some synoptic scale
data which was incorporated into the 00Z cycle. Therefore Miami and south FL seem to be in
less danger from Frances, but there is still a long way to go.

Both quite similar at the moment, although Andrew took a more northerly bend than Frances
is forecast too, but it wouldn't take too much to bend out west and make a dash for Miami
and Southern Florida again.
Indeed, that's not beyond the realms of probability. Depends what model is closest to
reality. Also, Hermine has crept into the scene. Anyway, looks like I've got a busy week.

Dear All,
The latest Intermediate Advisory (21A) from NHC has Frances SLP up to 959mb (or hPa, for
SH readers). That's quite a rapid rise in the last few hours, and I'm beginning to think
Frances might be about to fall apart. Any comment?

The latest fix is back down to 957- and it looks better on the satellite, so despite the
recent weakening, the storm is hardly falling apart. It may go through a few more
fluctuations the next several days, but overall I think it will probably remain a major
hurricane, but may never regain the extreme strength it once had. Anything is possible,
though,

According to the 0900Z discussion, Frances has been experiencing some southerly shear,
which is forecast to lessen in about 36 hrs. Also, recon found outer wind maxima, which
suggest the hurricane will likely continue to undergo eyewall replacement cycles, which
usually result in fluctuations in intensity.

The overall cloud structure of hurricane Frances is better organized this morning, the
cloud sheild is much rounder on the western semicircle than 24 hours ago. Cirrus clouds
are moving more outward on the west side than 24 hours ago. The faster forward motion
indicates the ridge has built in as the models had indicated earlier. Long range tracking
looks more like a South Carolina hit than a Florida hit right now. The approach to the
coast looks similar to hurricane Floyd except this time this storm will probably not
recurve to the NE as it approaches the coast.

Hi to all...
Hurricane Frances now is accelerating and moving closer to the Northern Leeward Islands
now Puerto Rico is under a tropical storm watch and tropical storm conditions will probaby
be felt here late tomorrow as the storm makes it CPA to the island probably around 110nm
north of San Juan and closer to Fajardo (NE tip of Puerto Rico, and Culebra). It will
depend in the wind radii and distance of the storm from Puerto Rico to see if tropical
storm force winds will be felt and how strong they will be. The storm now seems to be
deepening slowly and may be a cat-4 at CPA so great images from the radar will be able to
be seen from here. Will continue to update you from Puerto Rico and how conditions become
tomorrow as hurricane Frances works its way westward just north of here...
Stay Tuned
P.S. This storm looks as a good prospect for chasing in the NW or Central Bahamas...

Model guidance continues to be rather inconsistent- the new GFS has shifted way to the
left/east, with landfall in North Carolina Sunday.
However, most other models- SEF/ECMWF/Japanese are sticking to the FL landfall scenario-
the JMA actually has Frances moving through the Keys and into the Gulf. Bottom line- a US
landfall still seems very likely, where/when still very much in question- personally I am

The data I looked at has the 1898 hurricane as a 2 when it hit SAV (I use the great Unisys
site at http://weather.unisys.com/hurricane/atlantic/
). According to the data, the area from north of DAB to the GA/SC border has been
affected 10 times with hurricanes since 1851- the last being David in 1979. As Jim
mentioned before, Dora hit north FL in 1964 as a 3. A cat 1 hit SAV in 1940, then you go
all the way back to 1898, when 2 hurricanes hit GA- the first was actually just barely
into SC on Aug 31, but came close enough to affect the GA area. The second was a 90 kt
storm that hit on Oct 2. Before that the 1800s had a lot more storms hit this area- ones
in 1854 (3), 1871 (2), 1881 (2), 1885 (3), and 1895 (this one skimmed the FL and GA coast
as a 3 then a 2).
PS- this analysis only counts storms that come in from the east or south- not ones that
crossed FL first from the Gulf.

Looks like they have the old HURDAT info. It was a Category 4, about 938 mb with ~115 kt
based upon some great work Al Sandrik (NWS JAX) and Brian Jarvinen did with using SLOSH
and matching observed storm surge with the model. (The change officially was made back in
July 2003, so i don't know why unisys is so slow in showing the upgrade.)

Based on forecasted ridge trends, if Frances speeds up just a tad, a south of Jacksonville
strike becomes much more likely. Lest we forget the ridge lessons of Andrew before we head
the ridge lessons of Floyd.
Eye wall replacement cycles, while navigating the idiosyncrasies of the Bahamas (minor
terrain and ocean shallowness factors), could be just enough to make her precise course
less than smooth. And nautical mile fluctuations here, can translate into State-sized
location differentials by the weekend.

Well said Michael.
To expand just a bit on your comments, given the uncertainty w/r/t
how much/how fast the track will bend more poleward, it is not out
of the range of possibilities for Frances to wind up scraping a large
part, and perhaps even the entire east coast of Florida from PBI
northward. The 340-345 degree orientation of the peninsula could
very well allow for this scenario to pan out.

Allow me to be more explicit. Change "scraping" to "affect with sustained
hurricane force winds".
Given the TS and HURCN force wind radii, it is becoming almost a certainty that the entire
east coast of Florida will have at least *some* affect
from Frances.

I've always been taught, and observed it to be true, that the English name
'Frances' is feminine, and 'Francis' is masculine. I've never known of a guy named
'Frances', although I think I have heard of a female named 'Francis'.
The WMO Region IV Committee report last year stated that 'Frances' would be retired after
2004 due to a complaint by the rep from France. But, Lixion told me personally in Miami
that it would not be retired, since it was a common American name. HOWEVER, unless the
models are TOTALLY off-beam, I think now that is a mute point.
A large even Cat. 3 or possibly even Cat. 2 storm striking the SE U.S. anywhere from Miami
to Cape Hatteras would almost certainly cause enough damage to be retired, e.g., Fran,
Floyd, Isabel.

This weakness in the ridge/vort lobe that may pull Frances north is likely the reason why
the models keep waffling back and forth...the GFS has been doing so ever since the storm
was at 350ish hours in the future, a time where it's unfair/unwise to look at its output.
Welcome to the world of Medium Range, where all you can depend upon is the longwave
pattern, and the vorts can't be timed...or trusted.
Lately, it seems that a number of cyclones have had major features to affect their motion
(like deep troughs/warm core ridges/a solid TUTT), so there was some certainty even out
3-5 days. Not with Frances.
I'll check the teleconnections maps we have when I go to work tomorrow. I remember us
mentioning at the end of last week (at work...don't think we put that in the EPD) that the
models were missing a trough that should be developing somewhere in the Western Atlantic
considering the longwave pattern expected across North America, right about where the
models are waffling on the vort lobe embedded in the large ridge. It's unusual to get a
large, solid ridge that wide across the Atlantic/eastern North America...the longwave
pattern usually demands a break, somewhere.
Someone at work "pinned" me down to a landfall location yesterday...I said the
Carolinas, considering how this season has gone so far and the expected stronger weakness
that I was thinking would materialize in future model runs...this expected deeper solution
hasn't materialized yet. I've erred to the east on three TCs this year, as well as several
last year...and haven't erred west since Claudette and Erika last season. If that doesn't
send Frances to Florida, nothing will.
Working the phones for the relatives in Florida, already...the media in FL must be having

Didn't something similar happen with Klaus in 1990? It was a minimal hurricane that never
impacted any land significantly if I remember correctly, but I read somewhere that name

I can't find any season since 1964 in which two IH have hit Florida in the same season.
However, in 1964 neither hurricane was a cat four at landfall, and they were farther apart
in time. If Frances is a cat four at landfall, Florida will have taken an incredibly rare
double-blow...that alone makes one think that it might not be a major storm at landfall.

For what it's worth, the GFS model is showing Frances going up along the eastern seaboard
of the US almost like Floyd99. I don't believe it though ... and the main difference
between the synoptic pattern around Frances versus other recurving storms is that the
subtropical anticyclone is stronger than climatology and extends back into the eastern US.
Also, weather will be cooler than normal over eastern Canada. In the past, storms have
recurved here when our weather prior to the TC was warm and humid, but that setup is not
going to happen this time. Based on these synoptic scale indicators, I honestly do believe
this one will hit Florida. Bad situation for them. I also notice that storms tend to
attain cat-4 or 5 status when the subtropical anticyclone is very strong and extends well
into the NA continent.

Yikes indeed- I agree with the new TPC forecast of a southward shift in the track- the 06Z
eta is back on message after the odd northward shift with the 00Z run- I think that we can
pretty safely discard the GFS/GFDL solutions...it will be interesting to see if the 06Z or

Date: 09/03/2004 00:50 Subject: Re: 02/00z Model Forecasts for Frances
Awfully quiet on here.....
The GFS/GFDL have come around as I thought they might- so FL is in trouble. The storm has
weakened slightly again, due to another eyewall replacement, but that may be bad news as
well, as it may go through a stronger phase before or during landfall, but that is
impossible to tell. The outflow is as good as it gets, so I see no reason to doubt it will
maintain this intensity at least before hitting.
The only other question is the exact landfall point- it seem like the FLL- VRB corridor is
the place in general, then TPC and the new GFS take it inland the rest of the way.
However, the eta, which has actually been handling the storm pretty well so far, takes it
back over the Gulf- and the old UKMET and NOGAPS had similar paths. So the storm at least
has a shot to restrengthen and make a second landfall along the Gulf coast. So the bottom
line is that some of the uncertainty with Frances is over, it still may have a few
surprises in store.

FWIW, I really don't think Frances will recover Cat. 4 status.
However, the 100-mph sustained wind from Eleuthera warrants keeping Frances at Cat. 3
status until it should weaken further.
Given that the true MSW are likely occurring in a very small area, who can say that the
anemometer actually experienced them? That's only 11 mph under Cat. 3 levels.

Oh, many will grumble and sputter. They should look over at Port Charlotte and be
very thankful that they were spared a Cat. 4 hurricane. But many will criticize NHC that
their Labor Day weekend was spoiled by boarding up and leaving for a 'mere' Cat. 2
hurricane. Hopefully for such people, a sinkhole will open up and swallow their homes.
> Anyway, food for thought. Up until this latest series of forecast
(reintensifying the hurricane inspite of its return to Cat 2 status), I think the
NHC has done the best that they could with the situation...
I think the possibility of reintensification has to be kept before the public until it
become more or less certain that it won't happen. Especially coming on the heels of all
the criticism of the failure to forecast Charley's RI episode.
RE Tropical Storm Ivan---the forecast track keeps it south of 15N all the way from 30W to
60W. If it verifies, that will be pretty remarkable. Atlantic
TCs very rarely travel across 2000 miles of ocean remaining at such low latitudes.

Looks less likely this storm will be a major of an impact as thought yesterday- unexpected
shear is keeping the outflow restricted on the west side of the storm, and this is helping
keep the eye from re-forming. Therefore the pressure continues to slowly rise. If this
shear does not lessen soon, the chance for a comeback is lessened. In fact, it now seems
possible that the storm will not even be a major hurricane at landfall. Of course, it is
still over warm h20, the landfall looks like it will be delayed until tomorrow evening or
night, so it may still have another surprise up its sleeve, But for now, it looks like the
biggest impact (not inconsiderable) from Frances when all is said and done, will be
flooding. Remind you of another storm?
Floyd scared the **&^% out of everybody, caused massive evacuation, weakened, but
still caused a lot of damage from flooding.

Well Jose Garcia here from Puerto Rico and myself are here waiting patiently for this
storm to make its move. Right now we're looking at maybe the Ft. Pierce area as it looks
now. The hurricane at the moment looks quite un-impressive but I think it should become
better organized by this evening. The western semicircle has improved some this morning
although so far the convection is somewhat shallow so far.
Jose is supposed to get back to Puerto Rico Monday just in time for hurricane Ivan.

I think another factor for assessing the overall impact of a hurricane which is often
overlooked is the size, especially the diameter of the zone of hurricane-force winds. HU
Opal in our area is a great testimony to the widespread and sometimes severe damage which
can result when you have even 75-80 kt winds covering a wide area. Hundreds of thousands
of trees were downed, many of them falling on houses and mobile homes.
Based on the forecast/advisory wind radii, Charley's hurricane-force swath was 40 nm at
landfall--Frances' hurricane winds currently cover an area 150 nm across. Sustained
hurricane force winds in a heavily populated area with lots of trees are going to cause
much damage, even if not of the degree of destruction caused by Charley and Andrew.

Howdy yall,
Looks like Frances may want to pay a visit to me up in Jacksonville.
Hurricane Watch is now in effect for my area (Fernadina to Flager Bch) and the track seems
lifting further N & W.

Just had first sight of the latest UKMET run and it slows Frances to a canter in the next
day with landfall not until about 06Z on Sunday.
Interesting to see whether other models follow suit or whether this is just an 'outlier'.
If this does happen might there be more time for the shear to relax and re-intensification
to occur or might the issue of upwelling of cooler water then come into play with such a
slow-moving system?

If it slows down over the Gulf Stream, I doubt upwelling will be too much of a factor.
After all, it is replenished with warmer water to the south at about 4 kts and the Gulf
Stream's warm water is deeper than the surrounding waters. It wouldn't weaken as much as
it might over the Bahama Bank, had it stalled there.
The parents evacuate from Palm Beach Gardens to the south (Grandma's place in Deerfield)
within the next couple hours. My aunt and cousin had to evacuate yesterday, since their
places were within blocks of the Atlantic in Hollywood.

Regardless of how bad Frances affects FL, I think the fact the it passed through the
Bahamas as a Cat 3/4 and severely impacted the islands would likely justify the name being
retired at the end of the season.
