.DISCUSSION...NUMERIOUS SHOWERS AND THUNDERSTORMS HAVE BEGUN TO
BUILD OVER MUCH OF PUERTO RICO AND THE SURROUNDING ISLANDS THIS
MORNING. EXPECT THESE SHOWERS TO CONTINUE THROUGH THE AFTERNOON
HOURS...AS SUFFICIENT INSTABILITY AND PLENTY OF LOW LEVEL MOISTURE
WILL SUPPORT WIDESPREAD ACTIVITY. ONLY MINOR ADJUSTMENTS MADE TO

RADAR...SATELLITE AND MODEL DATA...AND NO ADJUSTMENTS MADE BEYOND 24
HOURS AT THIS TIME.

ACTIVITY WITHIN THE PAST TWO HOURS. DOPPLER RADAR IS DETECTING AT
THIS HOUR...ISOLATED TO SCATTERED SHOWERS ACROSS THE ADJACENT
COASTAL WATERS OF THE SOUTHWEST PORTION OF THE ISLAND. THESE
SHOWERS COULD BE AFFECTING THAT AREA IN THE NEXT HOUR OR SO AS
THESE SHOWERS MOVE TOWARD THE WEST NORTHWEST UNDER A SOUTHEAST
WIND FLOW.

SYNOPSIS...STRONG HIGH PRESSURE SYSTEM ACROSS THE NORTH CENTRAL
ATLANTIC THIS MORNING WILL SLOWLY MOVE TOWARDS THE NORTHEAST
WITHIN THE NEXT SEVERAL DAYS. AS A RESULT...MODERATE EAST SOUTHEAST
WIND FLOW WILL PERSIST ACROSS THE LOCAL AREA THROUGH THE UPCOMING
WEEKEND.

AT MID TO UPPER LEVELS OF THE ATMOSPHERE...HIGH PRESSURE SHALL
DOMINATE THE FA FOR THE NEXT SEVERAL DAYS. AT LOW LEVELS...PATCHES
OF MOISTURE AND CLOUDS WILL CONTINUE TO MOVE ACROSS THE LOCAL AREA
TO INTERACT WITH LOCAL ISLAND EFFECTS AND DIURNAL DAYTIME HEATING
TO PRODUCE AFTERNOON SHOWERS AND THUNDERSTORMS MAINLY ACROSS THE
WESTERN HALF SECTION OF THE ISLAND.

WATERS AND WINDS RANGING FROM 12 TO 18 KNOTS. SMALL CRAFT SHOULD
