AREA FORECAST DISCUSSION FOR THE FLORIDA KEYS
NATIONAL WEATHER SERVICE KEY WEST FL
915 PM EDT MON OCT 29 2012

.DISCUSSION...SATELLITE IMAGERY OVERLAID WITH AVAILABLE MODEL
STREAMLINE ANALYSIS AS OF 800 PM DETAIL THE ASTONISHINGLY LOW 946 MB
SURFACE CENTER OF GARGANTUAN SIZED NOW "EXTRA" TROPICAL CYCLONE
"SANDY" NOW MOVING ACROSS SOUTHERN NEW JERSEY. WATER VAPOR IMAGERY
IN ASSOCIATION WITH THE JETSTREAM AT THE BASE OF THE LARGE CYCLONE
ILLUSTRATE DEEP MID AND UPPER CYCLONIC FLOW OVER SOUTH FLORIDA AND
THE FLORIDA KEYS. THE 00Z EVENING SOUNDING ILLUSTRATES A FRESH TO
STRONG DRY NORTHWEST FLOW FROM JUST OFF OF THE SURFACE UP TO 5000
FEET AGL...BECOMING STRONG AND WESTERLY ABOVE THAT UP TO ABOUT 20000
FEET. A 5 DEGREE C INVERSION WAS IN PLACE FROM ABOUT 820 UP TO ABOUT
800 MB.

.CURRENTLY...AS OF 800 PM...SKIES ARE PARTLY TO MOSTLY CLOUDY WITH A
DECENT CANOPY OF STRATOCUMULUS IN PLACE OVER THE ISLANDS AND
ADJOINING WATERS. TEMPERATURES OVER THE ISLANDS RANGE FROM THE
MIDDLE 60S IN THE UPPER KEYS...TO AROUND 70 IN THE MIDDLE AND LOWER
KEYS...WITH DEWPOINTS BETWEEN 50 AND 55 DEGREES. C-MAN STATIONS ARE
RECORDING NORTHWEST WINDS BETWEEN 20 AND 25 KNOTS WITH GUSTS TO NEAR
30 KNOTS.

.FORECASTS...OVERNIGHT...A VERY DEEP MID AND UPPER TROUGH WILL
REMAIN IN PLACE OVERNIGHT...AND THE UNUSUALLY INTENSE SURFACE LOW
CENTER ASSOCIATED WITH EXTRA TROPICAL CYCLONE SANDY WILL CONTINUE TO
MOVE WESTWARD ACROSS PENNSYLVANIA AND SLOWLY FILL. THE UNUSUALLY
LARGE SURFACE CIRCULATION IN ASSOCIATION WITH "SANDY" IN COMBINATION
WITH HIGH PRESSURE OVER THE CENTRAL CONUS...WILL CONTINUE TO FUNNEL
UNSEASONABLY COOL AND DRY AIR SOUTH SOUTHEASTWARD ACROSS THE EASTERN
GULF OF MEXICO...TO ACROSS THE KEYS OVERNIGHT. THEREFORE...WE
EXPECT  A CONTINUATION OF STEADY FRESH NORTHWEST WINDS THROUGH THE
REST OF THE EVENING AND A FEW HOURS AFTER MIDNIGHT...BUT THEREAFTER
MODELS DO SHOW SOME LULLING IN THE MAGNITUDE OF THE WINDS DURING THE
PREDAWN HOURS. THE CONTINUED MODERATE COLD AIR ADVECTION OVER THE
KEYS WILL ALSO ALLOW FOR TEMPERATURES TO FALL DOWN TO BETWEEN 55 AND
60 DEGREES ACROSS PORTIONS OF THE UPPER KEYS...AND INTO THE MIDDLE
60S OVER THE MIDDLE AND LOWER KEYS. AND ALSO WITH THE RELATIVELY
COOLER AIR ACROSS THE WARM GULF WATERS...WE WILL ALSO CONTINUE TO
ANTICIPATE BROKEN TO OVERCAST STRATOCUMULUS CIGS OVER THE MIDDLE AND
LOWER KEYS...WITH CLEAR SKIES OFF OF THE UPPER KEYS. THEREFORE NO
CHANGES NEEDED ATTM.

.MARINE...
SMALL CRAFT ADVISORIES REMAIN IN EFFECT FOR ALL ZONES TONIGHT. A
LARGE NORTH-NORTHEAST SWELL WILL PERSIST IN THE STRAITS OF FLORIDA
OFFSHORE THE UPPER FLORIDA KEYS WHILE A LARGE NORTHWEST SWELL
PERSISTS IN THE SOUTHEASTERN GULF OF MEXICO.

.COASTAL FLOOD ADVISORY...THE COMBINATION OF THE UNUSUALLY LARGE YET
NOW INLAND CIRCULATION OF EXTRA TROPICAL CYCLONE SANDY...WITH A FULL
MOON TONIGHT...WILL CONTINUE TO ALLOW FOR THE FIFTH CONSECUTIVE
NIGHT OF MINOR COASTAL FLOODING THROUGH PART OF THE KEYS...WITH
TIDES OF 1 TO 2 FEET ABOVE NORMAL STILL EXPECTED. MINOR FLOODING IS
MOST LIKELY TO OCCUR AT LOCATIONS IN THE KEYS EXPOSED TO FLORIDA BAY
AND THE GULF WATERS. SOME ROADS MAY CONTINUE TO BE COVERED IN UP TO
ONE FOOT OF WATER. PLEASE CLICK ON THE COASTAL FLOOD ADVISORY LINK

.AVIATION...VFR CONDITIONS WILL PREVAIL AT BOTH THE KEY WEST
INTERNATIONAL AND MARATHON ISLAND TERMINALS. SCATTERED TO BROKEN
CEILINGS ARE POSSIBLE BUT WELL ABOVE OPERATIONAL CEILINGS. WINDS
WILL BE OUT OF THE WEST TO NORTHWEST AROUND 15 KNOTS WITH FREQUENT
GUSTS TO 20 KNOTS...WITH SOME HEAD AND TAIL WIND CONCERNS FOR
SMALLER AIRCRAFT.
