SPOT FORECAST FOR BURN...FHP
NATIONAL WEATHER SERVICE MIAMI FL
737 PM EST SUN JAN 18 2009

FORECAST IS BASED ON IGNITION TIME OF 2000 EST ON JANUARY 18.
IF CONDITIONS BECOME UNREPRESENTATIVE, CONTACT THE NATIONAL WEATHER
SERVICE.

.DISCUSSION...CLEAR SKIES...LIGHT WINDS...AND INCREASED LOW LEVEL
MOISTURE IS EXPECTED TO RESULT IN SOME FOG FORMATION ACROSS THE LOCAL
AREA OVERNIGHT. IT IS A RATHER TRICKY FORECAST...SINCE THERE IS A
COLD
FRONT APPROACHING THE REGION OVER THE GULF OF MEXICO. THIS COULD
ALLOW THE WINDS TO INCREASE TOWARDS DAWN...AND THUS LIMITING THE FOG
POTENTIAL. INCREASING CLOUDS TOWARDS DAWN COULD LIMIT THE POTENTIAL
FOR FOG AS WELL. HOWEVER...AT THIS TIME...AM FORECASTING WINDS TO BE
LIGHT ENOUGH AND THE CLOUDS TO BE DELAYED TO ALLOW FOR AREAS OF FOG
TO DEVELOP. ALTHOUGH DENSE FOG IS NOT EXPECTED...VISIBILITIES COULD
FALL TO NEAR A MILE IN SOME AREAS. THE FOG POTENTIAL WILL CONTINUE
TO BE ASSESSED TONIGHT...AND ANY UPDATES WILL BE ISSUED AS NEEDED.
