What forecasters said that day

The local office's own words before this small craft advisory went out, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.

NWS Key West, FL wrote its last area forecast discussion before this small craft advisory went out at Feb 24, 10:42 PM EST, 5 hours 52 minutes earlier.

Area forecast discussion, Feb 24, 10:42 PM EST, 5 hours 52 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE KEY WEST FL
1042 PM EST WED FEB 24 2016

.DISCUSSION...
CHANGES TO FORECAST -- A SMALL CRAFT ADVISORY FOR HAZARDOUS SEAS WAS
ISSUED FOR THE WESTERN PORTIONS OF THE MARINE SERVICE AREA DUE TO
SEAS BUILDING TO 7 TO 9 FEET DUE TO FRESH WEST-NORTHWEST SWELLS.
OVERNIGHT LOW TEMPERATURES WERE DROPPED A FEW DEGREES GIVEN LATEST
OBSERVATIONAL TRENDS AND GUIDANCE. WEATHER AND POP ELEMENTS WILL BE
ADJUSTED SHORTLY AS RAIN ENDS ACROSS THE AREA.

CURRENT SITUATION/ANALYSIS -- A SQUALL LINE WEAKENED GRADUALLY AS IT
TRAVERSED THE FLORIDA KEYS AND ADJACENT COASTAL WATERS FROM WEST TO
EAST. AT THIS POINT...ONLY A BROKEN SHOWER LINE COINCIDENT WITH A
SHEAR LINE AND WIND SURGE IS EVIDENT IN RADAR/SATELLITE IMAGERY
APPROACHING THE BAHAMA BANKS. THE COLD FRONT FOLLOWS THIS SHEAR LINE
CLOSELY...WHILE A MIX OF STRATIFORM AND CONVECTIVE PRECIPITATION
AREAS TRAIL THE FRONT IN A 100-MILE WIDE BAND...WITH A SHARP BACK
EDGE HAVING JUST PASSED THE DRY TORTUGAS. AN INTENSE WAVE CYCLONE IS
EVOLVING OVER THE OHIO VALLEY-GREAT LAKES...WHILE A LOW-LATITUDE HIGH
PRESSURE CELL REMAINS CENTERED WELL WEST OF THE AREA...ALONG THE
TEXAS/MEXICO COASTAL PLAINS. GRADIENT FLOW IS NOT ALL THAT IMPRESSIVE
WITH NORTHWEST BREEZES BLOWING MAINLY IN THE 15-20-KNOT RANGE. AIR
TEMPERATURES HAVE DROPPED ALREADY INTO THE UPPER 60S IN MOST KEYS
ISLAND COMMUNITIES...WITH DEWPOINT TEMPERATURES DOWN 5-10 DEGREES F
FROM EARLIER TODAY.

PROGNOSTIC OVERVIEW -- RAIN SHOULD CLEAR OUT BY JUST AFTER MIDNIGHT
MOST AREAS...WITH TRAILING BROKEN-OVERCAST STRATOCUMULUS DECKS. LOW-
LEVEL COLD THERMAL ADVECTION WILL INCREASE...ESPECIALLY TOWARD
SUNRISE...WITH AIR TEMPERATURES LIKELY REACHING THE MID 60S MOST
AREAS. TEMPERATURES MAY STRUGGLE TO REACH 70F ON WEDNESDAY.
&&

.MARINE...
A SMALL CRAFT ADVISORY FOR HAZARDOUS SEAS HAS BEEN ISSUED FOR THE
EXTREME SOUTHEASTERN GULF OF MEXICO BEYOND FIVE FATHOMS...INCLUDING
DRY TORTUGAS AND REBECCA SHOAL CHANNEL...AND FOR THE STRAITS OF
FLORIDA WEST OF THE SEVEN MILE BRIDGE. A COLD FRONT WILL SWEEP
SOUTHEASTWARD ACROSS THE STRAITS OF FLORIDA OVERNIGHT. A HIGH
PRESSURE SYSTEM WILL MOVE EASTWARD OVER THE GULF OF MEXICO AND
FLORIDA PENINSULA THURSDAY THROUGH SUNDAY.
&&

.AVIATION...
THROUGH 25/24Z...PREVAILING VFR CONDITIONS ARE EXPECTED AT BOTH EYW
AND MTH. ISOLATED POCKETS OF MVFR CEILINGS OR VISIBILITY ASSOCIATED
WITH LIGHT RAIN AREAS WILL END FROM WEST TO EAST BY 25/06Z. FRESH
NORTHWEST TO NORTH BREEZES WILL CREATE CROSSWINDS OCCASIONALLY
EXCEEDING 15 KNOTS AT BOTH EYW AND MTH.
&&

.KEY WATCHES/WARNINGS/ADVISORIES...
FL...NONE.
GM...SMALL CRAFT ADVISORY FOR HAZARDOUS SEAS IN EFFECT FOR
