544 AM EDT TUE OCT 16 2012

...A RED FLAG WARNING IS NOW IN EFFECT FROM 1 PM EDT /NOON CDT/ 
THIS AFTERNOON TO 7 PM EDT /6 PM CDT/ THIS EVENING...FOR ALL OF 
THE FLORIDA BIG BEND AND PANHANDLE (EXCEPT FOR DIXIE AND LAFAYETTE 
COUNTIES) DUE TO LOW AFTERNOON RELATIVE HUMIDITIES...COMBINED WITH 
HIGH DISPERSIONS AND HIGH ERC VALUES...

.EVEN WITH A SLIGHT PULLBACK IN MIXING HEIGHTS ACROSS THE TRI-
STATE AREA (NOW UNDER 5000 FT ALL AREAS)...THE TRANSPORT WIND
SPEEDS ARE STILL STRONG ENOUGH TO SUPPORT DISPERSIONS ACROSS THE
FLORIDA BIG BEND AND PANHANDLE RANGING FROM 77 TO THE SE TO 104 TO
THE N AND W. THE ONLY 2 COUNTIES WITH BELOW 75 DSIS WERE DIXIE AND
LAFAYETTE...SO WENT AHEAD AND UPGRADED THE VAST MAJORITY OF THE
FIRE WEATHER WATCH TO A RED FLAG WARNING...AS RELATIVE HUMIDITIES
ARE PLENTY LOW ENOUGH (MIDDLE 20S) AND ERCS ARE NOW FORECAST TO BE
ABOVE 20 AT ALL OF THE FLORIDA ZONES...WITH EVEN SOME LOWER 30S
EXPECTED TO RAMP UP ACROSS MUCH OF THE PANHANDLE AS WELL AS LEON
AND WAKULLA COUNTIES IN THE BIG BEND. ON WEDNESDAY...A FEW SPOTS
MAY APPROACH LONG DURATIONS OF LOW RELATIVE HUMIDITY...BUT THIS
WILL REQUIRE ERCS OF 35 OR GREATER WITH DISPERSIONS SIGNIFICANTLY
LOWER THAN TODAY.
