RUNOFF FROM HEAVY RAINFALL OVER THE AREA WILL CONTINUE TO POSE 
FLOODING PROBLEMS OF SMALL STREAMS...CREEKS...RIVERS...AND POOR 
DRAINAGE AND LOW LYING AREAS. THESE RUNOFF WILL MOVE DOWNSTREAM TO 
PORTUGUES RIVER BASIN. IN ADDITION...MUDSLIDES IN STEEP TERRAIN ARE 
LIKELY ACROSS THESE MUNICIPALITIES. 

EXCESSIVE RUNOFF WILL CAUSE FLOODING OF SMALL CREEKS AND STREAMS...
HIGHWAYS AND UNDERPASSES. ADDITIONALLY...LAND ALONG THE BANKS OF
CREEKS AND STREAMS AND OTHER LOW LYING AREAS ARE SUBJECT TO FLOODING.

ADO NOT DRIVE YOUR VEHICLE INTO AREAS WHERE THE WATER COVERS THE
ROADWAY. THE WATER DEPTH MAY BE TOO GREAT TO ALLOW YOUR CAR TO CROSS
SAFELY. MOVE TO HIGHER GROUND.

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SAN JUAN PR
254 PM AST SUN MAR 18 2012

.SYNOPSIS...A MID TO UPPER LEVEL TROUGH WEST NORTHWESTWARD OF THE
LOCAL AREA AND A JET STREAM ALOFT WILL REMAIN AS THE MAIN WEATHER
FEATURES ACROSS THE NORTHEAST CARIBBEAN FOR THE NEXT FEW DAYS.
SEVERAL PERTURBATIONS IN THE EAST NORTHEAST TRADE FLOW WILL MOVE
ACROSS THE LOCAL ISLANDS DURING THE NEXT FEW DAYS...SLIGHTLY
INCREASING THE CHANCES OF SHOWERS AND THUNDERSTORMS ACROSS THE
FA.

&&

.DISCUSSION...THE DYNAMIC PRODUCED BY A MID TO UPPER LEVEL TROUGH
WEST NORTHWEST OF THE REGION AND A JET STREAM ALOFT WILL CONTINUE
TO MAINTAIN SUFFICIENT INSTABILITY ACROSS THE NORTHEAST CARIBBEAN.
THESE FEATURES IN COMBINATION WITH DAYTIME HEATING AND SEA BREEZE
CONVERGENCE IS EXPECTED TO INDUCE THE DEVELOPMENT OF SCATTERED
SHOWERS AND ISOLATED THUNDERSTORMS MAINLY ACROSS WESTERN AND
INTERIOR SECTIONS PUERTO RICO EACH AFTERNOON DURING THE NEXT
SEVERAL DAYS. SEVERAL PERTURBATIONS IN THE EAST NORTHEAST TRADE
WIND FLOW WILL ALSO MOVE ACROSS THE LOCAL ISLANDS FROM TIME TO
TIME DURING THE NEXT FEW DAYS. THUS...EXPECT A LITTLE MORE
MOISTURE TO ADVECT ACROSS THE LOCAL ISLANDS THAN PREVIOUS DAYS. IN
FACT...ACCORDINGLY TO LATER TJSJ SOUNDINGS...PWAT VALUES ARE
SLIGHTLY INCREASING STEADILY AND GFS PWAT VALUES ALSO INDICATED
THE SAME TENDENCY. HOWEVER THESE VALUES OF PWAT DO NOT SUPPORT THE
DEVELOPMENT OF WIDESPREAD PCPN. OUTSIDE OF AREAS OF CLOUDINESS AND
PRECIPITATION...GENERALLY FAIR WEATHER IS EXPECTED.

DURING THE LATE MORNING HOURS...THE NWS DOPPLER RADAR INDICATED
ONLY FEW ISOLATED TO SCATTERED SHOWER ACTIVITY ACROSS THE
SURROUNDING COASTAL WATERS. LIMITED SHOWERS ACTIVITY WAS DETECTED
ELSEWHERE ACROSS THE FA DURING THE LATE MORNING HOURS. SCATTERED
SHOWERS AND ISOLATED THUNDERSTORMS START TO DEVELOP EARLY IN THE
AFTERNOON MAINLY ALONG AND SOUTH OF CORDILLERA CENTRAL. THIS
ACTIVITY IS EXPECTED TO PERSIST UNTIL THE LATE AFTERNOON OR EARLY
EVENING HOURS.
