AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SAN JUAN PR
645 AM AST SUN SEP 11 2005

.DISCUSSION...
AS THE NIGHT WENT BY...SHOWERS WERE ON THE INCREASE ACROSS THE LOCAL
AREA...BUT PARTICULARLY OVER THE COASTAL WATERS. ALL THIS WEATHER
CAN BE ATTRIBUTED TO A BROAD TROPICAL WAVE MOVING WESTWARD ACROSS
THE EASTERN CARIBBEAN. BASED ON SATELLITE PICTURES AND LATEST
QUICKSCAT PASS...THE WAVE AXIS IS NEAR 64 WEST EARLY THIS MORNING.
MOISTURE ASSOCIATED WITH WAVE WILL COMBINE WITH THE DIURNAL HEATING
AND THE TOPOGRAPHY TO PRODUCE ANOTHER ACTIVE WEATHER DAY ACROSS THE
LOCAL ISLANDS. ANY INTENSE SHOWER OR THUNDERSTORM WILL BE CAPABLE OF
PRODUCING HEAVY RAIN LEADING TO URBAN AND STREAM FLOODING.

THE WAVE IS EXPECTED TO EXIT THE LOCAL AREA THIS EVENING. BY EARLY
MONDAY...A LESS HUMID A MORE STABLE ATMOSPHERE WILL GRIP THE LOCAL
ISLANDS...FOR THE BEGINNING OF THE WORK WEEK...WITH ONLY ISOLATED TO
SCATTERED DIURNALLY INDUCED ACTIVITY EXPECTED EACH DAY. HOWEVER...
THE GFS MODEL IS SHOWING A SLIGHT INCREASE IN MOISTURE EARLY
TUESDAY...SO WE WILL PROBABLY SEE A FEW MORE SHOWERS ACROSS THE
U.S.VIRGIN ISLANDS AND THE EASTERN SECTORS OF PUERTO RICO DURING THE
NIGHT PERIOD AND EARLY MORNING HOURS.

LOOKING AHEAD...NO MAJOR CHANGES ARE EXPECTED IN THE WEATHER
PATTERN. THE TYPICAL TRADE WINDS WILL PREVAIL ACROSS THE LOCAL
REGION. AS A RESULT...AVAILABLE MOISTURE WILL COMBINE WITH THE LOCAL
EFFECTS EACH AFTERNOON...TO PRODUCE SOME CLOUDINESS...SCATTERED
SHOWERS AND ISOLATED THUNDERSTORMS OVER PARTS OF THE LOCAL ISLANDS
AND EACH NIGHT...SCATTERED SHOWERS OVER THE COASTAL WATERS AND EAST
COASTAL SECTIONS. THE TROPICAL WAVE NEAR 37 WEST EARLY THIS MORNING
IS FORECAST BY MODEL GUIDANCE TO ARRIVE NEXT SUNDAY.

&&

.MARINE...SMALL TO MODERATE NORTH NORTHEAST SWELLS WILL CONTINUE TO
AFFECT THE REGIONAL WATERS...INCLUDING THE MONA AND ANEGADA PASSAGES
TODAY. GENERALLY EXPECT WINDS OF 20 KNOTS OR LESS AND WAVE HEIGHTS
OF 5 FEET OR LESS.
