  EASTERN INTERIOR...MAYAGUEZ AND VICINITY...NORTH CENTRAL... 
  NORTHEAST...NORTHWEST...PONCE AND VICINITY...SAN JUAN AND

  ISLANDS. 

* THROUGH FRIDAY EVENING

* A MID TO UPPER LEVEL TROUGH WILL REMAIN LOCATED JUST WEST THROUGH 
  NORTH OF THE LOCAL AREA THROUGH FRIDAY. IN ADDITION...AN 
  ASSOCIATED SURFACE TROUGH WILL CONTINUE TO EXTEND NORTH ACROSS 
  THE LOCAL AREA FROM THE EASTERN CARIBBEAN...BRINGING ADDITIONAL 
  MOIST AND UNSTABLE AIR ACROSS THE REGION. THIS MOISTURE AND 
  INSTABILITY WILL COMBINE WITH THE MID TO UPPER TROUGH AND LOCAL 
  EFFECTS...TO PRODUCE SEVERAL ROUNDS OF SHOWERS AND THUNDERSTORMS 
  ACROSS THE LOCAL ISLANDS. THESE SHOWERS AND STORMS WILL BE SLOW 
  MOVING AND CAPABLE OF PRODUCING PERIODS OF INTENSE RAINFALL WITH 
  RATES OF AN INCH OR MORE PER HOUR. 

* RAINFALL AMOUNTS OF TWO TO FOUR INCHES ARE POSSIBLE... ESPECIALLY 
  ACROSS THE EASTERN THIRD OF PUERTO RICO...AS WELL AS PARTS OF THE 
  SOUTH COASTAL SECTIONS...AND THE U.S. VIRGIN ISLANDS DURING THE 
  NEXT 24 TO 36 HOURS. LOCALLY HIGHER AMOUNTS OF UP TO SIX INCHES 
  ARE POSSIBLE IN THE HIGHER ELEVATIONS OF PUERTO RICO. THESE 
  OVERALL AMOUNTS MAY BE SUFFICIENT TO CAUSE FLASH FLOODING OF 
  SMALL STREAMS...RIVERS AND DRY GUTS. 

PRECAUTIONARY/PREPAREDNESS ACTIONS...

A FLASH FLOOD WATCH MEANS THAT CONDITIONS ARE FAVORABLE FOR HEAVY
RAIN ACROSS THE WATCH AREA...WHICH MAY LEAD TO FLOODING. IF YOU ARE
IN THE WATCH AREA...CHECK YOUR PREPAREDNESS REQUIREMENTS...
ESPECIALLY IF YOU HAVE INTERESTS ALONG AREA RIVERS. KEEP INFORMED...
AND BE READY FOR QUICK ACTION IF FLOODING IS OBSERVED OR IF A FLASH
FLOOD WARNING IS ISSUED.

PEOPLE IN THE WATCH AREA SHOULD CONTINUE TO BE AWARE OF THE
POSSIBILITY FOR HEAVY RAINFALL. AVOID LOW LYING AREAS...AND BE
CAREFUL WHEN APPROACHING HIGHWAY DIPS AND UNDERPASSES. THE HEAVY
RAIN COULD ALSO CAUSE MUDSLIDES IN AREAS OF STEEP TERRAIN.

  THUNDERSTORMS MAY ALSO DEVELOP AT ANY TIME ACROSS THE VIRGIN
  ISLANDS BUT ARE MOST LIKELY ACROSS SAINT THOMAS LATE IN THE DAY
  AND EARLY EVENING. DUE TO THE ABUNDANT MOISTURE AND
  INSTABILITY...THESE SHOWERS MAY BE CAPABLE OF PRODUCING LOCALLY
  INTENSE RAINFALL RATES OF ONE TO THREE INCHES PER HOUR WHICH
  COULD CAUSE FLASH FLOODING OF SMALL STREAMS...RIVERS AND DRY
  GUTS. SHOWERS ARE EXPECTED TO DISSIPATE BY 8 PM IN MOST PLACES
  BUT MAY LINGER A BIT LONGER NEAR SAINT THOMAS.

  TROUGH EXTENDS FROM THE WEST CENTRAL ATLANTIC SOUTHWARD INTO THE
  CENTRAL CARIBBEAN. THIS BROAD TROUGHINESS WILL LINGER ACROSS THE
  GREATER ANTILLES AND LOCAL REGION WELL INTO THE WEEKEND. THIS
  FEATURE COMBINED WITH...THE COPIOUS AMOUNTS OF TROPICAL MOISTURE
  AND LOCAL AND DIURNAL EFFECTS...WILL CONTINUE TO PROVIDE THE
  NECESSARY FORCING TO GENERATE ENHANCED CONVECTIVE ACTIVITY
  ACROSS THE REGION ESPECIALLY DURING THE AFTERNOON AND LATE
  EVENING HOURS OVER LAND. THESE SHOWERS AND STORMS ARE EXPECTED
  TO DEVELOP ACROSS THE MUCH OF THE CORDILLERA CENTRAL OF PUERTO
  RICO...THEN DRIFT GENERALLY EASTWARD AROUND 5 TO 10 MPH. IN
  ADDITION...SHOWERS AND THUNDERSTORMS MAY ALSO DEVELOP AT ANY
  TIME ACROSS THE VIRGIN ISLANDS ESPECIALLY LATE IN THE DAY AND
  DURING THE EVENING HOURS. DUE TO THIS ABUNDANCE OF MOISTURE AND
  INSTABILITY... THE SHOWERS WILL CONTINUE TO PRODUCE PERIODS OF
  LOCALLY INTENSE RAINFALL RATES OF ONE TO THREE INCHES PER HOUR
  WHICH COULD LEAD TO ADDITIONAL FLASH FLOODING OF SMALL
  STREAMS... RIVERS AND DRY GUTS AND POOR DRAINAGE AREAS. MOST OF
  THE SHOWERS AND STORMS ARE EXPECTED TO DISSIPATE BY LATE EVENING
  IN MOST PLACES OVER PUERTO RICO...BUT SOME MAY LINGER A BIT
  LONGER AROUND THE VIRGIN ISLANDS AND OVER THE COASTAL WATERS.
  ALTHOUGH THE HEAVY RAINFALL WILL DIMINISH AT TIMES...RUNOFF FROM
  RECENT RAINS WILL CONTINUE TO AFFECT AREAS UNDER THE WATCH...AND
  RIVERS AND STREAM WILL REMAIN AT DANGEROUSLY HIGH LEVELS.
  ADDITIONAL RAINS WILL ONLY AGGRAVATE THE SITUATION...AND
  MUDSLIDES WILL CONTINUE TO BE A PROBLEM IN AREAS OF STEEP
  TERRAIN. FOR THIS REASON THE FLASH FLOOD WATCH HAS BEEN EXTENDED
  AT LEAST UNTIL SATURDAY AFTERNOON.

THE FLASH FLOOD WATCH FOR A PORTION OF PUERTO RICO HAS BEEN
CANCELLED. 

THE MID TO UPPER LEVEL TROUGH RESPONSIBLE FOR THE ENHANCEMENT OF
SHOWERS AND STRONG THUNDERSTORMS ACROSS THE REGION TODAY CONTINUED
TO WEAKENS AND SLOWLY LIFT NORTH NORTHEAST OF THE REGION.
ALTHOUGH THE AVAILABILITY OF AMPLE LOW LEVEL MOISTURE WILL STILL
LEAD TO SHOWERS AND ISOLATED THUNDERSTORM DEVELOPMENT MAINLY
DURING THE AFTERNOON AND EARLY EVENING OVER THE NEXT FEW DAYS...
WIDESPREAD HEAVY RAINFALL IS NO LONGER EXPECTED.

FOR THE NEXT FEW DAYS AFTERNOON SHOWERS AND THUNDERSTORMS ARE EXPECTED
TO DEVELOP ACROSS PARTS OF THE ISLAND. SHOWER ACTIVITY WILL BE MORE
LOCALIZED AND FOCUSED MAINLY ACROSS THE CENTRAL MOUNTAIN RANGE OF PUERTO
RICO. THE PROBABILITY OF WIDESPREAD SHOWERS AND EXCESSIVE RAINFALL NO
LONGER APPEARS HIGH ENOUGH TO WARRANT A CONTINUATION OF A FLASH FLOOD
WATCH.

THEREFORE...THE FLASH FLOOD WATCH HAS BEEN CANCELLED. KEEP IN MIND
HOWEVER THAT PERIODS OF LOCALLY HEAVY RAIN ON ALREADY SATURATED
SOIL WILL CONTINUE TO POSE A HAZARD...AND WILL LEAD TO LOCALIZED
URBAN AND SMALL STREAM FLOODING AT LEAST THROUGH MONDAY. IN ADDITION
DUE TO LOOSE AND SATURATED SOIL ESPECIALLY IN AREAS OF STEEP TERRAIN...

NUMEROUS SHOWERS AND ISOLATED THUNDERSTORMS ACROSS LARGE PORTIONS
OF OUR LOCAL FORECAST AREA. ON THURSDAY WILL VERY SIMILAR TO WHAT
OCCURRED TODAY...WITH MORNING SHOWERS ACROSS THE EASTERN PORTIONS
OF PUERTO RICO AND SCATTERED TO NUMEROUS SHOWERS AFFECTING THE
INTERIOR AND WESTERN PORTIONS OF THE ISLAND. ON FRIDAY...WINDS ARE
FORECAST TO DECREASE SIGNIFICANTLY...THIS WILL HELP LARGER AMOUNTS
OF RAINFALL ACCUMULATIONS OVER AREAS WITH SATURATED SOILS...
THEREFORE INCREASING THE CHANCES OF FLASH FLOODING

.AVIATION...BKN-OVC MID TO HIGH LEVEL CLOUDS AND SCT-BKN LOW LEVEL
CLOUDS WILL LINGER ACROSS THE LOCAL FLYING AREA DURG THE NXT 24 HRS.
EMBEDDED SHRA AND ISOLD TSRA WILL CONTINUE TO MOV WEST ACROSS THE

ACTIVITY. VCTS ALSO PSBL NR TJSJ...TISX...TIST TIL 03/12Z WITH MTN

.PREV DISCUSSION... /ISSUED 303 PM AST WED MAY 2 2012/

SYNOPSIS...MID/UPPER TROUGH IS EXPECTED TO MEANDER OVER THE
EASTERN BAHAMAS THROUGH THE END OF THE WEEK. THIS TROUGH PATTERN
ALOFT WILL ALLOW FOR SUBTROPICAL JET TO ESTABLISH ACROSS THE
NORTHEASTERN CARIBBEAN LATER IN THE WEEK. AA LOW LEVEL
INVERTED TROUGH WILL MOVE ACROSS THE EASTERN CARIBBEAN ISLANDS
THURSDAY THROUGH AT LEAST FRIDAY. RESULTING IN EVEN MORE
CLOUDINESS...AVAILABLE MOISTURE...AND SHOWER ACTIVITY.

DISCUSSION...NUMEROUS SHOWERS AND THUNDERSTORMS HAVE DEVELOPED
ACROSS PUERTO RICO TODAY. SOME THUNDERSTORMS WERE STRONG WITH VERY
FREQUENT AND INTENSE LIGHTNING...PARTICULARLY ACROSS THE WESTERN
INTERIOR SECTIONS OF PUERTO RICO. THE SAN JUAN METROPOLITAN AREA
AND NORTHEASTERN PUERTO RICO OBSERVED SHOWERS AND THUNDERSTORMS
BUT WERE NOT AS INTENSE. THE AVAILABLE MOISTURE HAS INCREASED
SIGNIFICANTLY IN THE PAST 24 HOURS AND ALSO THE OVERALL
INSTABILITY...WHICH CAUSED THE FAVORABLE CONDITIONS FOR THIS
ACTIVITY.

COMPUTER MODELS CONTINUE INSISTING IN EVEN MORE MOISTURE AND
INSTABILITY FOR THURSDAY. THEREFORE NUMEROUS SHOWERS AND ISOLATED
THUNDERSTORMS CONTINUE TO BE EXPECTED ON THURSDAY AND THURSDAY
AFTERNOON. THIS PATTERN IS EXPECTED TO CONTINUE UNTIL AT LEAST
FRIDAY.

AVIATION...NUMEROUS SHOWERS AND SOME THUNDERSTORMS ARE EXPECTED
ACROSS PUERTO RICO FOR THE REST OF THE AFTERNOON. MVFR CONDITIONS
ARE EXPECTED AT TJSJ...TJMZ AND TIST DUE TO LOWER CEILINGS AND
SHOWERS. VCTS ARE LIKELY FOR TJMZ AS STRONG THUNDERSTORMS ARE
DEVELOPING JUST EAST OF TJMZ. MOUNTAIN OBSCURATIONS ARE LIKELY DUE
TO THICK CLOUD COVER AND SHRA/TSRA. CONDITIONS TO IMPROVE AFTER
03/00Z LEAVING MOSTLY VFR CONDITIONS WITH PASSING SHOWERS. MVFR
CONDS WITH SHRA/TSRA ARE ONCE AGAIN EXPECTED FOR PR AND USVI AFTER
03/16Z.

MARINE...SMALL CRAFT SHOULD EXERCISE CAUTION AS SEAS ARE EXPECTED
TO BE UP TO 6 FEET TONIGHT...IMPROVING ON THURSDAY.
