IN THE NORTHWESTERN BAHAMAS...
A TROPICAL STORM WARNING REMAINS IN EFFECT FOR THE NORTHWESTERN
BAHAMAS FOR ELEUTHERA... THE ABACOS... AND GRAND BAHAMA ISLAND.
A TROPICAL STORM WARNING MEANS THAT TROPICAL STORM CONDITIONS ARE
EXPECTED WITHIN THE WARNING AREA WITHIN THE NEXT 24 HOURS.
FOR STORM INFORMATION SPECIFIC TO YOUR AREA...INCLUDING POSSIBLE
INLAND WATCHES AND WARNINGS...PLEASE MONITOR PRODUCTS ISSUED
BY YOUR LOCAL WEATHER OFFICE.
AT 8 AM EDT...1200Z...THE CENTER OF TROPICAL STORM FRANKLIN WAS
LOCATED NEAR LATITUDE 26.8 NORTH...LONGITUDE 77.4 WEST OR OVER THE
NORTHERN PORTION OF GREAT ABACO ISLAND. THIS IS ALSO ABOUT 80
MILES ... 130 KM...EAST OF FREEPORT ON GRAND BAHAMA ISLAND.
FRANKLIN IS MOVING TOWARD THE NORTHWEST NEAR 9 MPH...15 KM/HR. A
GRADUAL TURN TOWARD THE NORTH...WITH A DECREASE IN FORWARD SPEED...
IS EXPECTED DURING THE NEXT 12 TO 24 HOURS. THIS MOTION WOULD KEEP
THE CENTER OF FRANKLIN MOVING PARALLEL TO THE FLORIDA EAST COAST.
HOWEVER...SINCE FRANLIN IS A SMALL TROPICAL STORM...SOME ERRATIC
MOTION IS POSSIBLE.
MAXIMUM SUSTAINED WINDS ARE NEAR 45 MPH... 75 KM/HR...WITH HIGHER
GUSTS. SOME STRENGTHENING IS FORECAST DURING THE NEXT 24 HOURS.
TROPICAL STORM FORCE WINDS EXTEND OUTWARD UP TO 40 MILES... 65 KM
MAINLY TO THE EAST OF THE CENTER.
THE ESTIMATED MINIMUM CENTRAL PRESSURE IS 1008 MB...29.77 INCHES.
FRANKLIN MAY PRODUCE RAINFALL AMOUNTS OF 2 TO 4 INCHES OVER THE
NORTHERN BAHAMAS DURING THE NEXT 24 HOURS.
REPEATING THE 8 AM EDT POSITION...26.8 N... 77.4 W. MOVEMENT
TOWARD...NORTHWEST NEAR 9 MPH. MAXIMUM SUSTAINED
WINDS... 45 MPH. MINIMUM CENTRAL PRESSURE...1008 MB.

OK ... I thought they had the 11pm position too far north, but overnight Franklin has moved solidly northwest, so that's kind of a moot point. (Maybe that little comment about erratic movement was aimed at folks like me
)
Anyway, happily it looks like the looping option is gone and Franklin will be a fish.

TROPICAL STORM FRANKLIN DISCUSSION NUMBER 5
NWS TPC/NATIONAL HURRICANE CENTER MIAMI FL
11 AM EDT FRI JUL 22 2005
THE OVERALL CONVECTIVE APPEARANCE OF FRANKLIN HAS IMPROVED THIS
MORNING AND THE SHEAR ON THE WEST SIDE HAS LESSENED. THIS HAS
ALLOWED FOR CONVECTION TO DEVELOP ON THE WEST SIDE OF THE
CIRCULATION AND FOR THE CLOUD PATTERN TO BECOME MORE CIRCULAR. THE
SURFACE WIND FIELD HAS ALSO BECOME BETTER DEFINED AS NOTED BY A
1046Z QUIKSCAT OVERPASS AND SURFACE OBS FROM THE BAHAMAS AND
FLORIDA. AIR FORCE RECON FOUND 49 KT FLIGHT-LEVEL WINDS IN THE
SOUTHEAST QUADRANT... WHICH EQUALS ABOUT A 39-KT SURFACE WIND.
HOWEVER...THE ONBOARD METEOROLOGIST ESTIMATED SURFACE WINDS OF
55-60 IN THE SAME AREA. THEREFORE...THE INITIAL INTENSITY IS BEING
CONSERVATIVELY INCREASED TO 45 KT...BUT IT COULD BE A LITTLE
HIGHER.
THE INITIAL MOTION IS AN UNCERTAIN 330/02 KT. THE FIRST TWO RECON
POSITIONS HAVE COME IN EAST OF THE PREVIOUS ADVISORY POSITIONS...
AND THE MOST RECENT FIX CAME IN ABOUT 15 MILES NORTHEAST OF THE
FIRST ONE. SATELLITE IMAGERY AND RADAR DATA FROM MIAMI AND
MELBOURNE INDICATE LITTLE OVERALL NET MOTION...OTHER PERHAPS A SLOW
NORTHWESTWARD DRIFT. UPPER-AIR DATA AT 06Z AND 12Z INDICATE THAT
FRANKLIN APPEARS TO BE LOCATED ON THE SOUTH SIDE OF OR WITHIN A
FAIRLY STOUT MID- TO UPPER-LEVEL RIDGE. AS RESULT...THERE MAY BE
SOME SLOW ERRATIC MOTION TO THE NORTHWEST OR NORTH FOR THE NEXT 24
HOURS OR SO UNTIL A SHORTWAVE TROUGH OVER THE EASTERN OHIO AND
TENNESSEE VALLEYS MOVES EASTWARD TO THE U.S. EAST COAST AND WEAKENS
THE RIDGE AXIS TO THE NORTH OF FRANKLIN. THAT MAY ALLOW FOR MORE
SIGNIFICANT NORTHWARD AT THAT TIME AND...IF THE RIDGE WEAKENS AS
THE GLOBAL MODELS ARE FORECASTING...THEN THE CYCLONE WOULD MOVE
THROUGH THE RIDGE AND RECURVE TO THE NORTHEAST. HOWEVER...FRANKLIN
IS A VERY SMALL TROPICAL CYCLONE AND IT WOULD NOT TAKE MUCH RIDGE
TO THE NORTH TO KEEP THE CYCLONE FROM RECURVING OUT TO SEA AND TURN
TOWARD THE WEST. THIS ALTERNATE SCENARIO IS SUGGESTED BY THE
STATISTICAL-DYNAMICAL MODELS NHC98 AND A9UK...WHICH MAKE A SMALL
LOOP NORTH OF THE NORTHWESTERN BAHAMAS AND THEN TURN FRANKLIN BACK
TO THE SOUTHWEST AFTER 96 HOURS. THE DEEP AND MEDIUM BAM MODELS
HAVE ALSO PERSISTED WITH THEIR PREVIOUS SOLUTIONS OF SLOW
NORTHWESTWARD MOTION THROUGH 36-48 HOURS...AND THEN TURNING THE
CYCLONE WEST-SOUTHWESTWARD ACROSS SOUTH-CENTRAL FLORIDA IN 72-96
HOURS.
THE SHEAR ACROSS FRANKLIN HAS STEADILY WEAKEND THIS MORNING...AND
THE VARIOUS MODELS FORECAST THIS TO CONTINUE FOR AT LEAST THE NEXT
36-48 HOURS. THIS SHOULD ALLOW FOR AT LEAST SOME MODEST
STRENGTHENING TO OCCUR AS PER THE SHIPS AND GFDL MODELS. IF
FRANKLIN REMAINS STATIONARY EAST OF FLORIDA AND DOES NOT RECURVE AS
FORECAST...THEN THE INTENSITIES AFTER 48 HOURS WOULD LIKELY BE
HIGHER THAN INDICATED.
