AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SAN JUAN PR
509 PM AST MON SEP 8 2008

.DISCUSSION...ACTIVE TROPICAL WAVE MOVING ACROSS THE LOCAL AREA
LATE THIS AFTERNOON WILL CONTINUE TO PRODUCE MODERATE TO HEAVY
INTENSITY SHOWERS AND THUNDERSTORMS ACROSS MOST OF THE LOCAL
COASTAL WATERS AND FOR THREE QUARTER OF THE ISLAND OF PUERTO
RICO...CULEBRA AND VIEQUES AND SECTIONS OF THE U.S. VIRGIN ISLANDS
THROUGH AT LEAST THE OVERNIGHT HOURS.

EXPECT SQUALLY WEATHER ACROSS BOTH COASTAL AND LAND AREAS AS THESE
THUNDERSTORMS MOVE NORTH NORTHWESTWARD FOR THIS EVENING INTO THE
OVERNIGHT HOURS. A SECOND ROUND OF SHOWERS AND THUNDERSTORMS ARE
EXPECTED TO TRAVEL FROM THE CARIBBEAN WATERS TUESDAY MORNING TOWARDS
THE SOUTHERN COASTAL AREAS OF PUERTO RICO...INCLUDING CULEBRA AND VIEQUES.

WITH ALL THIS WEATHER OCCURRING AND ANTICIPATING EVEN MORE WEATHER
FOR THE NEXT 12 HOURS OR SO...A FLASH FLOOD WATCH WAS ISSUED FOR
THREE QUARTER OF PUERTO RICO...INCLUDING CULEBRA...VIEQUES AND THE
U.S. VIRGIN ISLANDS THROUGH 2 AM AST TUESDAY. THIS WATCH MAY BE
EXTENDED OR CANCELED PENDING OF WEATHER CONDITIONS LATE TONIGHT.

WEATHER CONDITIONS ARE ANTICIPATED TO PERSIST WET FOR MOST OF THE
LOCAL ISLANDS AND COASTAL WATERS THROUGH LATE WEDNESDAY. FOR THIS
REASONING...RESIDENTS AND VISITORS SHOULD MONITOR CLOSELY THE
WEATHER CONDITIONS FOR THE NEXT FEW DAYS AS NEW EPISODES OF
SHOWERS AND THUNDERSTORMS COULD IMPACT THEIR AREAS.
REMEMBER...MOST OF PUERTO RICOS SOIL ARE SATURATED DUE TO THE
PAST RECENT RAINS AND ONLY WOULD TAKE A LITTLE RAIN EVENT FOR THE
SMALL STREAMS AND RIVERS TO REACT AND COME OUT FROM THEIR BANKS.

PERIOD.

LATE THIS AFTERNOON AND EVENING...PERIODS OF MVFR AND POSSIBLE IFR
AS SQUALLS MOVE OVER THESE AREAS. UNSTABLE WEATHER CONDITIONS

AFTERNOON WILL MAINTAIN MVFR CONDITIONS FOR MOST OF TONIGHT FOR
TIST...TISX AND TJSJ.

&&

.MARINE...SEAS ARE AVERAGING 4 TO 6 FEET ACROSS MOST OF THE LOCAL
WATERS. A MODERATE TO FRESH SOUTHEASTERLY WIND FLOW WILL PERSIST
OVER THE REGIONAL WATERS THROUGH TUESDAY. THEREFORE...SMALL CRAFT
ARE URGED TO EXERCISE CAUTION ACROSS ALL LOCAL WATERS THROUGH
TUESDAY. HOWEVER...WINDS AND SEAS WILL BE MUCH HIGHER AS SQUALLY
