AREA FORECAST DISCUSSION...UPDATED
NATIONAL WEATHER SERVICE SAN JUAN PR
1211 PM AST WED APR 5 2006

.UPDATE...PRECIPITABLE WATER IS RISING AGAIN OVER PUERTO RICO AS
SHOWERS AND ISOLATED THUNDERSTORMS MOVE BRISKLY THROUGH THE AREA
ON EAST SOUTHEAST TRADE WINDS. THE GFS CONTINUES TO SHOW
INCREASING MOISTURE AND SHOWERS WILL DEVELOP EARLY OVER THE AREA.
LATEST RADAR SHOWS SHOWERS OVER NORTHWEST PUERTO RICO JUST AFTER
NOON AND AMOUNTS ARE HIGH. SOME AREAS WITH HEAVY RAINFALL
YESTERDAY WILL LIKELY SEE HEAVY AMOUNTS AGAIN TODAY AND THIS WILL
MAKE THEM MORE VULNERABLE TO FLOODING. HAVE UPDATED ZONES FOR
BETTER CHANCES OF RAIN OVER THE AREA. WINDS ARE SLIGHTLY STRONGER
AND SLIGHTLY DIFFERENT SO EXACT PATTERN WILL NOT BE THE SAME. SOME
POSSIBILITY OF FLASH FLOODING COULD OCCUR IF CELLS DEVELOP OVER THE
SAME AREAS HOWEVER SO SITUATION WILL BE MONITORED CLOSELY.

&&

.PREV DISCUSSION...SCATTERED SHOWERS CONTINUED ACROSS THE COASTAL
WATERS OVERNIGHT AND ARE CURRENTLY DEVELOPING ALONG THE NORTHEAST
COAST OF PUERTO RICO THIS MORNING. WHILE BRIEF PERIODS OF MODERATE
RAIN WILL BE ASSOCIATED WITH THIS SHOWER ACTIVITY...NO SIGNIFICANT
ACCUMULATION IS EXPECTED.

THE UPPER LEVEL TROUGH DIGGING TO THE WEST OF PUERTO RICO THIS
MORNING...COMBINED WITH AN INCREASE IN LOW LEVEL MOISTURE
TODAY...IS EXPECT TO ENHANCE DIURNAL SHOWER ACTIVITY THIS
AFTERNOON. WITH CONTINUED EAST SOUTH EAST FLOW EXPECTED AGAIN
TODAY...COULD SEE DIURNAL SHOWER ACTIVITY REACH INTO THE SAN JUAN
METRO AREA AS WELL AS MUCH OF THE NORTHERN SECTIONS OF PUERTO
RICO. WITH THIS IN MIND...URBAN AND SMALL STREAM FLOODING WILL THEREFORE
LIKELY BE A THREAT TO THE AREAS RECEIVING THE HEAVIEST RAINFALL
DURING THE AFTERNOON AND EVENING HOURS.

EXPECT THE CONTINUED PRESENCE OF THE TROUGH WEST OF PUERTO RICO
COMBINED WITH ABUNDANT LOW LEVEL MOISTURE...TO KEEP THE WEATHER
ACTIVE OVER PUERTO RICO AND THE U.S. VIRGIN ISLANDS AGAIN ON
THURSDAY...BEFORE SLIGHTLY DRIER AIR MOVES IN BEHIND THIS UPPER
LEVEL TROUGH FOR THE FIRST PART OF THE WEEKEND.

SYNOPSIS...HIGH PRESSURE OVER THE CENTRAL EAST ATLANTIC WILL
CONTINUE TO PRODUCE AN EAST SOUTHEASTERLY WIND OVER THE LOCAL
AREA...AS MOISTURE WILL CONTINUE TO INCREASE ACROSS THE AREA AHEAD OF
AN UPPER LEVEL TROUGH THAT IS EXPECTED TO DIG SOUTHWARD OVER THE
CARIBBEAN THROUGH EARLY FRIDAY.

MARINE...SMALL CRAFT SHOULD CONTINUE TO EXERCISE CAUTION ACROSS
THE OFF SHORE ATLANTIC WATERS AND CARIBBEAN PASSAGES DUE TO A MIX
OF EAST NORTHEAST WIND WAVES AND LONG PERIOD NORTH NORTHEAST
SWELLS.
