as it is 6-7 days from any possible US consequences..these updates (which come every 4 hours) are probably not "breaking news"

11 a.m. NHC Discussion:

HURRICANE FRANCES DISCUSSION NUMBER 11 NWS TPC/NATIONAL HURRICANE CENTER MIAMI FL 11 AM EDT FRI AUG 27 2004

FRANCES CONTINUES TO BECOME BETTER ORGANIZED WHILE STRENGTHENING TO 90 KT. THE INITIAL INTENSITY IS SUPPORTED BY A DVORAK SATELLITE INTENSITY ESTIMATE OF T5.0...OR 90 KT...FROM TAFB...A SATELLITE DATA T-NUMBER OF 5.0 FORM AFWA...AND 27/1010Z UW-CIMSS AMSU PRESSURE RETRIEVAL OF 969.8 MB...WHICH EQUATES TO ABOUT 90 KT. THE OUTFLOW REMAINS EXCELLENT AND ALSO CONTINUES TO IMPROVE.

THE MOTION IS NOW 300/09. FRANCES REMAINS ON TRACK AND HAS BEGUN TO SLOW DOWN. A NORTHWESTWARD JOG MAY OCCUR...BUT IT IS EXPECTED TO BE SHORT-LIVED AS THE WEAKNESS IN THE SUBTROPICAL RIDGE TO THE NORTH OF FRANCES IS FORECAST TO QUICKLY FILL IN AS THE SHORTWAVE TROUGH NOTED IN WATER VAPOR IMAGERY ALONG 52W LONGITUDE CONTINUES TO ZIP ALONG EASTWARD. THE NHC MODEL GUIDANCE IS IN STRONG AGREEMENT ON A WEST-NORTHWEST TO NORTHWESTWARD TRACK THROUGH 48 HOURS...BUT THEN DIVERGE SIGNIFICANTLY AFTER THAT. HOWEVER...DESPITE THE DIFFERING TRACKS...ALL OF THE MODELS AGREE ON HIGH ZONAL FLOW WITH STRONG WESTERLIES DEVELOPING ACROSS THE NORTHERN U.S. AND THE NORTH ATLANTIC AFTER 48HR. SUCH A STRONG HIGH-LATITUDE ZONAL FLOW PATTERN IS USUALLY REFLECTED BY A STRONG SUBTROPICAL RIDGE TO THE SOUTH THAT EXTENDS EAST-WEST FROM THE AZORES TO BERMUDA AND INTO THE SOUTHEASTERN U.S. MY CONCERN IS THAT THE RIDGE MAY BUILD IN FASTER THAN EXPECTED AND DRIVE FRANCES MORE WESTWARD SOONER THAN FORECAST ...WHICH IS WHAT THE 06Z GFS MODEL IS INDICATING. HOWEVER...MAKING SUCH A SUDDEN AND SHARP 45 DEGREE LEFT-OF-TRACK TURN AT 48 HOURS IS PROBABLY OVERDOING IT SOME...BUT OUT OF RESPECT FOR THE CONSISTENT TREND IN THE GFS MODEL THE PAST 24 HOURS...THE FORECAST TRACK HAS BEEN NUDGED A LITTLE MORE SOUTH AND WESTWARD IN 72-120HR.

FRANCES IS EXPECTED TO REMAIN IN A LOW SHEAR ENVIRONMENT AND OVER INCREASING SSTS THROUGHOUT THE PERIOD...SO AT LEAST SOME SLOW INTENSIFICATION SHOULD OCCUR. THE SHIPS MODEL SHARPLY BRINGS DOWN THE INTENSITY TO 73 KT AFTER 72 HOURS DUE TO INCREASING WESTERLY SHEAR OF 25-30 KT. HOWEVER...THE VERTICAL SHEAR IS FICTITIOUS AND 'SELF-INFLICTED' BY THE GFS/SHIPS MODEL...DUE TO THE OFFICIAL FORECAST TRACK BEING ABOUT 180 NMI NORTH OF THE GFS FORECAST POSITIONS IN 72-120H. THIS PUTS FRANCES IN THE STRONG WESTERLY FLOW IN THE NORTHERN SEMICIRCLE OF A VERY INTENSE UPPER-LEVEL HIGH THAT ALL THE MODELS DEVELOP OVER FRANCES. THE SHIPS MODEL WAS DISCOUNTED AND THE OFFICIAL INTENSITY FORECAST LEANS TOWARD THE GFDL SOLUTION.

FORECASTER STEWART FORECAST POSITIONS AND MAX WINDS INITIAL 27/1500Z 15.0N 49.0W 90 KT 12HR VT 28/0000Z 15.8N 50.4W 100 KT 24HR VT 28/1200Z 17.0N 52.1W 100 KT 36HR VT 29/0000Z 18.0N 53.6W 105 KT 48HR VT 29/1200Z 18.9N 55.2W 105 KT 72HR VT 30/1200Z 20.2N 58.5W 110 KT 96HR VT 31/1200Z 21.0N 62.0W 110 KT 120HR VT 01/1200Z 22.0N 67.0W 110 KT

I disagree. If the hurricane is in the Florida Straits, it would have to turn south across Cuba to enter the Caribbean. Most forecasts I've seen have it not going that far south.

No, it doesn't - that map doesn't even show it going near the Caribbean. And, as I said earlier, if the hurricane is in the Florida Straits, it is already north of the Caribbean at that point - the Southern Cuban coast is the farthest north the Caribbean reaches.

Point is, the track is not written in stone, so all interests in the Caribbean, South Florida, etc. need to monitor this hurricane. Read the NHC Discussion that I posted. Thanks.

Be a dear and find the track of Isabel for me. I've got this sinking feeling in the pit of my stomach, thinking that this one looks eerily familiar.

assuming the bahamas are loosely referred to as "northern carribean".....which is may be wrong but i think they are...then the northern carribean is in the track.

Actually, some are comparing Frances more to Hurricane Andrew track in 1992.

I'll be keeping an eye on this one myself:

Lessee...1 aunt, 1 cousin and family in Ocala...1 sis and family in St Pete, 1 cousin and family in Palm Coast, 1 cousin and family in West Palm Beach, 1 cousin and family in Miami...

And to top it all off...

Hubby just started two months of Navy Aircraft Mechanic A School at NAS Pensacola...

Oh and kids and I are in VA Beach...

What you posted isn't quite correct:

NHC Track map has Frances aimed for the Florida Straits and N. Caribbean during the next week!

The track map doesn't aim it towards the Caribbean - it keeps it north. There is an outside chance that Frances could veer WSW and hit the northern islands - but that would happen over the weekend. If no such turn happens, the next threat would be potentially to the Turks and Caicos islands and the Bahamas by midweek, followed by the Florida Straits and the east coast of Florida towards the end of the week.

So there is a very remote threat to the NE and Northern section of the Lesser Antilles within the next 72 hours.

The track of this storm was closer to Andrew, but it's staying slightly further to the south and is stronger now than Andrew was. They keep pushing the forecast track more to the west and south - but I don't think it would move with any kind of southerly component.
