AREA FORECAST DISCUSSION...UPDATED
NATIONAL WEATHER SERVICE KEY WEST FL
1017 PM EDT THU MAY 14 2015

.UPDATE...
BASED ON THE LATEST HOURLY OBSERVATIONS FROM THE CMANS ALONG THE
REEF AND THE OVERALL TREND FROM THE PAST FEW HOURS...DECIDED TO
RAISE A SMALL CRAFT ADVISORY FOR THE FLORIDA STRAITS AND HAWK
CHANNEL. THESE ELEVATED CONDITIONS WILL LIKELY PERSIST THROUGH
FRIDAY AND POSSIBLY INTO FRIDAY NIGHT. AN EXERCISE CAUTION FOR SMALL
CRAFT HAVE BEEN HEADLINED ELSEWHERE IN THE KEYS SERVICE AREA.

04

=====================================================================
.DISCUSSION...
SHOWERS HAVE REMAINED CLUSTERED OFF MAINLAND MONROE COUNTY...MAINLY
BEYOND 20 NM FROM SHORE...AND IN THE ATLANTIC WATERS WELL OFFSHORE
FROM THE MIDDLE AND UPPER KEYS. A FEW STROKES OF LIGHTNING HAVE
ACCOMPANIED THE STRONGER CELLS IN BOTH LOCATIONS. SKIES ARE PARTLY
CLOUDY ELSEWHERE IN THE KEYS SERVICE AREA. WINDS ARE MODERATE TO
OCCASIONALLY FRESH FROM THE EAST...SURGING OVER THE PAST HOUR OR SO.
TEMPERATURES ALONG THE ISLAND CHAIN ARE IN THE LOWER 80S.

THE EVENING LOCAL SOUNDING SHOWS SOMEWHAT DRIER AIR HAS PUSHED INTO
THE LOCAL AREA ALOFT ON THE DEEP MODERATE TO FRESH EASTERLY BREEZES.
BUT WE ARE OBVIOUSLY MOIST AND UNSTABLE ENOUGH TO SUPPORT AT LEAST
SCATTERED SHOWERS WITH A FEW THUNDERSTORMS. AND WE EXPECT THIS TO
CONTINUE OVERNIGHT. THE AFTERNOON ZONE FORECAST HAS THE EXPECTED
CONDITIONS COVERED THROUGH THE OVERNIGHT PERIOD. NO UPDATE IS PLANNED
AT THIS TIME.

&&

.MARINE...
READ UPDATED SECTION ABOVE.

&&

.AVIATION...
WILL MONITOR THE CONVECTION OFFSHORE IN THE ATLANTIC FOR THE
THREAT OF SUB-VFR CONDITIONS AT EITHER KEY WEST OR MARATHON. THE
TENDENCY THUS FAR HAS BEEN FOR CELLS TO WEAKEN AS THEY PUSH ANYWHERE
NEAR THE REEF. WILL KEEP VFR CONDITIONS ADVERTISED FOR NOW AT BOTH
LOCATIONS. EXPECT EASTERLY BREEZES GUSTING TO NEAR 20 KNOTS
OVERNIGHT.
