Reading the latest Discussion on Fay. I caught this little bit of information.

THE MODEL CONSENSUS HAS SAGGED A LITTLE TO THE SOUTH...AND
SO HAS THE OFFICIAL TRACK. ALTHOUGH THE FORECAST POINTS LISTED
BELOW DO NOT EXPLICITLY INDICATE IT...THE EXACT FORECAST TRACK HUGS
THE GULF COAST OF THE FLORIDA BIG BEND AREA AT 36 TO 48 HOURS. IF
FAY ENDS UP MOVING FARTHER SOUTH THAN FORECAST...AND SPENDS MORE
TIME THAN FORECAST OVER THE NORTHEASTERN GULF...IT COULD BE AT
TROPICAL STORM STRENGTH A COUPLE OF DAYS FROM NOW.
IF...HOWEVER...IT MOVES NORTH OF THE OFFICIAL TRACK...IT COULD
WEAKEN FASTER THAN INDICATED BELOW.

REGARDLESS OF THE EXACT TRACK...FAY WILL BE MOVING RATHER SLOWLY
DURING THE NEXT SEVERAL DAYS...POSING A SIGNIFICANT HEAVY RAINFALL
AND FLOODING HAZARD TO A VERY LARGE AREA.
