AREA FORECAST DISCUSSION FOR THE FLORIDA KEYS
NATIONAL WEATHER SERVICE KEY WEST FL
346 PM EDT THU AUG 25 2011

.DISCUSSION...
.CURRENTLY...
AN OUTFLOW BOUNDARY FROM HURRICANE IRENE IS DISSIPATING OVER THE
LOWER KEYS WITH THE ONLY SHOWER AND THUNDERSTORM ACTIVITY CURRENTLY
SHOWING UP ON THE KBYX RADAR IS BEYOND 20 NM SOUTH OF THE UPPER AND
MIDDLE KEYS...AND OVER MIAMI-DADE COUNTY WITH ALL ACTIVITY HEADING
SOUTH SOUTHEAST AT 25 TO 30 KNOTS. THE ACTIVITY OVER THE MAINLAND IS
HEADING TOWARD THE UPPER KEYS. WINDS HAVE BEEN THE BIGGER ISSUE TODAY
WITH NORTHWEST WINDS AROUND 15 KNOTS AND GUSTY...AND 15 TO 20 KNOTS
WEST OF 7 MILE BRIDGE...NEAR 20 KNOTS IN THE EASTERN AREAS FROM
C0-MAN STATIONS WITH HIGHER GUSTS. THE VISIBLE SATELLITE IMAGE OF
HURRICANE IRENE IS IMPRESSIVE AS THE STORM BEGINS TO LIFT MORE TO THE
NORTH AWAY FROM THE BAHAMAS.

.SHORT TERM (TONIGHT THROUGH SATURDAY)...
HAVE RECOMBINED THE LOWER AND MIDDLE KEYS WHILE LEAVING THE UPPER
KEYS BROKEN OUT IN THE FORECAST. EXPECT THAT THE MAIN IMPACT WILL BE
WINDS WHICH WILL TAKE A BIT LONGER TO SUBSIDE ALONG THE EASTERN
ZONES BEFORE THE INFLUENCE OF HURRICANE IRENE LIFTS TO THE NORTH. THE
FORWARD SPEED OF THE SYSTEM WILL INCREASE DURING THE NEXT 12 TO 16
HOURS BACKING OUR WINDS AROUND FROM NORTH NORTHWEST TO WEST BY
SATURDAY. WINDS WILL SUBSIDE FROM WEST TO EAST THROUGH SATURDAY AS
WELL. WILL KEEP CLIMATOLOGICAL POPS IN AS THE SUBSIDENCE AROUND IRENE
WILL MOVE OUT AND THE AREA RETURNS TO A MORE MOISTURE RICH
ENVIRONMENT WITH OVER 100 PERCENT OF NORMAL VALUES.

&&

.LONG TERM (SUNDAY THROUGH THURSDAY)...
BACK TO THE NORMAL WET SEASON ENVIRONMENT WITH VERY LITTLE LEFT OVER
AFFECTS FROM IRENE...WITH 40 PERCENT POPS THROUGH THURSDAY. THE
PRESSURE GRADIENT WILL CONTINUE TO RELAX THROUGH TUESDAY WHILE THE
ATLANTIC RIDGE OF HIGH PRESSURE REBUILDS. WEDNESDAY THE RIDGE WILL BE
BACK IN PLACE AND WINDS WILL TURN MORE FROM THE EAST.

&&

.MARINE...
THE SMALL CRAFT ADVISORY FOR FLORIDA BAY...THE BAYSIDE AND GULFSIDE
WATERS EAST OF SNIPE POINT...HAWKS CHANNEL AND THE STRAITS OF FLORIDA
FROM SEVEN MILE BRIDGE EASTWARD WILL REMAIN AT THIS TIME. LATEST
WIND OBSERVATIONS FROM LONG KEY AND SOMBRERO KEY C-MAN STATIONS
WARRANT AT LEAST ONE MORE PERIOD BEFORE SLIDING THE ADVISORY TO THE
EASTERN STRAITS. WITH OUTFLOW BOUNDARIES FROM HURRICANE PASSING OVER
THESE WATERS EXPECT THAT MARINE WARNINGS ARE POSSIBLE THIS EVENING AS
THE STORM MOVES OUT OF INFLUENCE. A REMNANT CAUTIONARY STATEMENT WILL
BE NEEDED ON THE REMAINDER OF THE KEYS WATERS THIS EVENING AND WILL
BE DISCOUNTED FROM WEST TO EAST AS WINDS DECREASE THROUGH TONIGHT.

&&

.AVIATION...
THROUGH 12Z...OUTSIDE OF A POSSIBLE...BRIEF MVFR/IFR ENCOUNTER...VFR
CONDITIONS WILL PREVAIL AT THE KEY WEST AND MARATHON TERMINALS.
NORTHWEST WINDS OF 10 TO 15 KNOTS WITH GUSTS OF AROUND 20 KNOTS WILL
TURN WEST TOWARD FRIDAY MORNING.
