AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SAN JUAN PR
330 PM AST THU SEP 17 2009

.SYNOPSIS...MID TO UPPER LEVEL LOW THAT AFFECTED THE LOCAL AREA
YESTERDAY HAS QUICKLY MOVED AWAY FROM THE DISCUSSION AREA WITHIN THE
PAST 24 HOURS. THIS FEATURE IS EXPECTED TO CONTINUE MOVING AWAY
FROM CWA WHILE IT TRACKS WEST SOUTHWEST INTO THE CENTRAL CARIBBEAN
WATERS FOR THE NEXT FEW DAYS. ANOTHER UPPER LOW LOCATED EARLY THIS
AFTERNOON NEAR 20N 54W IS PROJECTED TO PUSH WESTWARD THROUGH AT
LEAST THE UPCOMING WEEKEND. SUBSIDENCE IN FROM OF THIS LOW WILL
DRY THINGS OUT ACROSS THE LOCAL AREA...NOT PERMITTING WIDESPREAD
CONVECTION OVER THE LOCAL ISLANDS FOR THE NEXT COUPLE OF DAYS.

SURFACE HIGH PRESSURE EXTENDING FROM THE NORTH CENTRAL
ATLANTIC SOUTHWEST TO THE NORTHEAST CARIBBEAN...WILL MAINTAIN A
GENTLE TO MODERATE TRADE WIND FLOW ACROSS THE AREA FOR THE NEXT
SEVERAL DAYS.

DISCUSSION...LOW LEVEL MOISTURE HAS DIMINISHED ACROSS THE LOCAL AREA AS
SUGGESTED BY 12Z TJSJ SOUNDING...WHICH CAME OUT WITH 1.85 PW VALUE
VS 2.09 FROM 00Z LAST NIGHT. ALSO...THE SAN JUAN ASOS GPS-MET
INTEGRATED PRECIPITABLE WATER VAPOR ESTIMATED VALUES HAVE CAME
DOWN FROM OVER 2 INCHES TO 1.78 INCHES SINCE LAST NIGHT THROUGH
NOW. HOWEVER...MODERATE TO LOCALLY HEAVY SHOWERS AND THUNDERSTORMS
HAVE DEVELOPED ACROSS THE CENTRAL INTERIOR AND PARTS OF WESTERN
PUERTO RICO...INDUCING MUDSLIDES AND MINOR ROADWAYS FLOODING
MAINLY OVER UTUADO AND VICINITY...DUE TO THE COMBINATION OF LOCAL EFFECTS
AND DIURNAL HEATING.

THIS ACTIVITY MAY LAST FOR THE NEXT COUPLE OF HOURS...BEFORE
SHOWERS AND THUNDERSTORMS DIMINISH OR MOVE AWAY FROM LAND AREAS.
IT SHOULD BE A PLEASANT EVENING THROUGH FRIDAY MORNING ACROSS THE
LOCAL ISLANDS WITH MAINLY ISOLATED SHOWERS AFFECTING THE SOUTH AND
SOUTHEASTERN COASTS OF THE ISLANDS.

FOR THE UPCOMING WEEKEND...FAIR WEATHER CONDITIONS ARE EXPECTED
FOR MUCH OF THE AREA WITH TYPICAL SUMMER SHOWER ACTIVITY EXPECTED
FOR THE WESTERN INTERIOR SECTION OF PUERTO RICO.
AN INCREASE OF LOW LEVEL MOISTURE AND SHOWERS IS ANTICIPATED FOR
SUNDAY AND MONDAY OF NEXT WEEK.

&&

.AVIATION...VFR CONDITIONS ARE EXPECTED ACROSS ALL LOCAL TAF SITES
THROUGH AT LEAST LATE TONIGHT. ALTHOUGH...PASSING SHOWERS AND FEW
THUNDERSTORMS COULD AFFECT THE AREA OF PONCE...MAYAGUEZ AND
AGUADILLA LATE THIS AFTERNOON THROUGH SUNSET (BRIEFLY MVFR FROM

A LAS 306 PM AST EL RADAR DOPPLER DEL SERVICIO NACIONAL DE
METEOROLOGIA INDICO GRUPOS DE AGUACEROS FUERTES CON TRONADAS A
TRAVES DE ESTOS MUNICIPIOS.

LLUVIAS FUERTES PUEDEN CAUSAR INUNDACIONES EN AREAS BAJAS Y
DE POBRE DRENAJE COMO EN ZANJAS. EVITE ESTAS AREAS Y NO CRUCE
CARRETERAS INUNDADAS. LOS NIVELES DE AGUA DE RIACHUELOS Y RIOS
TAMBIEN PUEDEN SUBIR...POR LO TANTO BUSQUE AREAS ELEVADAS SI SE
ENCUENTRA BAJO AMENAZA DE INUNDACION. ESTOS AGUACEROS SERAN CAPACES
DE PRODUCIR HASTA UNA PULGADA POR HORA CAUSANDO ESTANCAMIENTO DE
AGUA EN LAS CARRETERAS. SE LES ACONSEJA A LOS MOTORISTAS A REDUCIR
LA VELOCIDAD Y USAR PRECAUCION ADICIONAL EN LAS CARRETERAS.
DESLIZAMIENTOS DE TIERRA SON POSIBLES EN AREAS DE TERRENO EMPINADO.

RELAMPAGOS INTENSOS ESTAN REPORTADOS CON ESTA TORMENTA. SI SE
ENCUENTRA AL AIRE LIBRE...QUEDESE AFUERA DE OBJETOS ALTOS AISLADOS
COMO LOS ARBOLES. BUSQUE REFUGIO SI ES POSIBLE. CUANDO ESTE BAJO
TECHO...MANTENGASE ALEJADO DE LAS VENTANAS Y PUERTAS Y EVITE USAR EL
TELEFONO A MENOS QUE SEA UNA EMERGENCIA. TRATE DE DESCONECTAR LOS
DISPOSITIVOS ELECTRICOS ANTES DE QUE LA TORMENTA SE ACERQUE.
