AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SAN JUAN PR
521 PM AST TUE DEC 23 2008

.DISCUSSION...NO MUCH WEATHER GOING ON AT THIS TIME ACROSS OUR
LOCAL AREA. A FEW PATCHES OF CLOUDS AND ISOLATED SHOWERS ACROSS
THE NORTHEASTERN CARIBBEAN WILL CONTINUE TO PUSH SOUTHWESTWARD AS
FRESH TO STRONG NORTHEASTERLY WIND BLOW DOMINATES THE FORECAST
AREA. LATER THIS EVENING INTO THE OVERNIGHT HOURS...A SECOND PATCH
OF CLOUDS WILL BE MOVING CLOSE TO THE LOCAL ISLANDS...WHICH MAY
RESULT IN SCATTERED SHOWERS TO LOCALIZED NUMEROUS SHOWERS MAINLY
ACROSS THE NORTHERN COAST OF PUERTO RICO. AFTERWARD...WEATHER
CONDITIONS ARE EXPECTED TO IMPROVE WITH PARTLY CLOUDY SKIES
ANTICIPATED FOR MOST OF THE AREA WITH ISOLATED TO SCATTERED
SHOWERS TO AFFECT MAINLY THE EASTERN HALF OF PUERTO RICO.

FOR CHRISTMAS DAY...EXPECT A WET MORNING FOR THE NORTHERN COASTS
OF THE LOCAL ISLANDS...BUT SLOWLY IMPROVING AS THE DAY GOES BY.
REST OF THE WEEK AND THE UPCOMING WEEKEND LOOKS PLEASANT FOR MOST
OF THE LOCAL AREA ACCORDING TO THE LATEST MODEL GUIDANCE.

NOW...THE BIGGEST CONCERN FOR THE NEXT FEW DAYS WILL BE THE WINDS
AND THE MARINE CONDITIONS ACROSS THE AREA WATERS.
A STRONG HIGH PRESSURE MOVING OFF THE EASTERN COAST OF THE UNITED
STATES WILL MOVE ACROSS THE WESTERN ATLANTIC WITHIN THE NEXT
COUPLE OF DAYS...CREATING BREEZY TO WINDY CONDITIONS ACROSS THE
LOCAL ISLANDS AND COASTAL WATERS. WINDS FROM THIS FEATURE WILL
COMBINE WITH A WIND SURGE MOVING ACROSS THE NORTHEASTERN CARIBBEAN
TO CREATE WINDS AND HAZARDOUS SEAS CONDITIONS ACROSS OUR LOCAL
WATERS BEGINNING TONIGHT INTO AT LEAST THURSDAY AFTERNOON.

DUE TO THESE MARINE CONDITIONS EXPECTED TO OCCUR FOR AT LEAST FOR
A GOOD PORTION OF THE REMAINDER OF THE WEEK...SMALL CRAFT
ADVISORIES ARE IN EFFECT FOR MOST OF THE LOCAL COASTAL WATERS
THROUGH THURSDAY AFTERNOON.

STAY TUNED FOR UPDATED INFORMATION AS WE GET CLOSER TO THE PEAK OF
THIS WINDY EVENT LATE WEDNESDAY INTO THURSDAY.

&&

.AVIATION...VFR CONDITIONS WITH NO OPERATIONAL IMPACTS EXPECTED
FOR THE REST OF TODAY OTHER THAN WINDS. WINDS WILL CONTINUE NELY
IN THE 15 TO 20 KT RANGE AT MOST SITES UNTIL 21-22Z...THEN
DROPPING 10 TO 15 KNOTS FOR THE EVENING AND OVERNIGHT. SIGNIFICANT
EMISSIONS CONTINUE FROM SOUFRIERE HILLS VOLCANO IN
MONTSERRAT...BUT NELY WIND FLOW WILL KEEP PLUME AWAY FROM LOCAL
FLYING AREA. SEE SIGMETS AND VAASAB FOR DETAILS OF VA OVER WATERS
OF THE EASTERN CARIBBEAN.
