SPOT FORECAST FOR DEEP FIRE...NPS BIG CYPRESS
NATIONAL WEATHER SERVICE MIAMI FL
643 AM EDT WED MAY 6 2009

FORECAST IS BASED ON REQUEST TIME OF 0700 EDT ON MAY 06.
IF CONDITIONS BECOME UNREPRESENTATIVE, CONTACT THE NATIONAL WEATHER
SERVICE.

.DISCUSSION...VERY SIMILAR CONDITIONS TO THE PAST SEVERAL DAYS
ANTICIPATED AT THE FIRE SITE. SMOKE/FOG MIXTURE SHOULD BEGIN TO
DISPERSE BETWEEN 8 AND 9 AM AS MIXING BEGINS AND WINDS PICK UP
FROM CALM TO SOUTHEAST AT 5-10MPH. DEEP MIXING EXPECTED ONCE AGAIN
BUT LIGHT SOUTHEASTERLY ATMOSPHERIC WINDS WILL LIMIT DISPERSION
INDICES. GULF COAST SEA BREEZE SHOULD MOVE THROUGH THE FIRE SITE
DURING THE LATE AFTERNOON WITH WIND SHIFT TO THE SW AND POSSIBLY A
SHOWER OR TWO. WINDS BECOME LIGHT EASTERLY THIS EVENING BEFORE
GOING CALM AGAIN OVERNIGHT. THIS WILL ALLOW SMOKE TO SETTLE TO THE
GROUND AND MIX WITH FOG, LEADING TO DANGEROUSLY LOW VISIBILITIES
ONCE AGAIN OVERNIGHT ON AREA ROADWAYS.
