514 AM AST WED MAY 25 2011

.SYNOPSIS...AREA OF LOW PRESSURE ACROSS THE CENTRAL ATLANTIC
EXTENDING SOUTHWEST TO JUST NORTH OF THE LEEWARD ISLANDS...AND HIGH
PRESSURE ACROSS THE WEST ATLANTIC WILL HELP TO CREATE AND MAINTAIN A
VERY LIGHT NORTHEAST TO EAST WIND FLOW ACROSS THE REGION THROUGH AT
LEAST THURSDAY. MID TO UPPER LEVEL HIGH PRESSURE RIDGE WILL REMAIN
IN PLACE ACROSS THE LOCAL AREA THROUGH THURSDAY...THEN GRADUALLY
WEAKEN/ERODE BY FRIDAY AS A SHORT WAVE THROUGH IS FORECAST TO MOVE
ACROSS THE WEST ATLANTIC AND NORTH OF THE REGION INTO THE WEEKEND.

LEVEL CLOUDS LIFTING NORTHEAST ACROSS THE REGION ...WHILE PATCHES OF
LOW LEVEL MOISTURE ALONG AN OLD FRONTAL SH EARLINE/WEAK CONVERGENCE
ZONE EXTENDED SOUTHWEST INTO THE NORTHEAST CARIBBEAN. MIMIC
SATELLITE DERIVED PRECIPITABLE WATERS ANALYSIS...AS WELL AS PREVIOUS
TJSJ 25/00Z UPPER AIR SOUNDING AND GROUND BASED GPS MET DATA...
INDICTED PWAT VALUES STILL LINGERED AROUND 2.0 INCHES WITH MOST OF

THE EAST COASTAL SECTIONS OF PUERTO RICO...AND PARTS OF THE NORTHERN
VIRGIN ISLANDS. NO SIGNIFICANT RAINFALL AMOUNTS ARE EXPECTED AT
THE IS TIME.

DURING THE REST OF THE DAY ...THE GENERALLY LIGHT WIND FLOW ACROSS

AGAIN LEAD TO AFTERNOON CONVECTION ACROSS ISOLATED SPOTS IN THE
VIRGIN ISLANDS...BUT MAINLY ACROSS THE CORDILLERA CENTRAL OF PUERTO
RICO. SOME OF THE SHOWERS AND ISOLATED AFTERNOON THUNDERSTORMS
WILL PRODUCE PERIODS OF MODERATE TOLOCALLY HEAVY RAINFALL. THIS
MAY ONCE AGAIN LEAD TO URBAN AND SMALL STREAM FLOODING IN SOME AREAS.
IN ADDITION...RIVERS AND STREAMS REMAIN AT HIGH LEVELS ACROSS PARTS
OF NORTHERN PUERTO RICO...THEREFORE ANY ADDITIONAL RAINFALL MAY CAUSE
SOME OF THESE RIVERS TO QUICKLY REACT AND LEAD TO QUICK RISES IN THE
RIVERS AND STREAMS.

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SAN JUAN PR
941 PM AST WED MAY 25 2011

.UPDATE...ANOTHER ACTIVE AFTERNOON WAS SEEN ACROSS THE NORTHERN
SLOPES OF PUERTO RICO. THE HEAVIEST RAINFALL OCCURRED OVER DORADO...
TOA BAJA...CATANO AND SAN JUAN. RADAR ESTIMATES AND RAIN GAGES
INDICATED RAINFALL AMOUNTS BETWEEN 2 TO 4 INCHES IN PARTS OF
DORADO...TOA BAJA AND CATANO. OTHER AREAS OF SAN JUAN...TRUJILLO
ALTO AND MOROVIS RECEIVED AT LEAST 2 INCHES OF RAIN. SOME RIVERS
ARE HIGH AT THIS TIME...ESPECIALLY RIO CIBUCO...RIO LA PLATA NEAR
TOA ALTA AND RIO RIO PIEDRAS.

SATELLITE AND RADAR IMAGERY INDICATES SCATTERED SHOWERS MAINLY
ACROSS THE LOCAL ATLANTIC WATERS AND A FEW LIGHT TO MODERATE
SHOWERS OVER THE SOUTH CENTRAL SECTIONS OF PUERTO RICO. LATEST
SOUNDING AT TJSJ AND SATELLITE DERIVED TPW SHOWED VERY MOIST AND
UNSTABLE ATMOSPHERE WITH PWAT VALUES AROUND 2.25 INCHES ACROSS THE
LOCAL AREA. THE MID/UPPER LEVEL RIDGE JUST SOUTH OF THE LOCAL AREA
WILL SHIFT SLIGHTLY TO THE NORTHEAST TOMORROW...FAVORING AND UPPER
LEVEL CONVERGENCE PATTERN ALOFT. HOWEVER...THE INVERSION IS NOT
EXPECTED TO BE NEARLY AS STRONG AND SCATTERED AFTERNOON SHOWERS
AND THUNDERSTORMS WILL LIKELY DEVELOP ALONG THE INTERIOR AND NORTH
SECTIONS OF PUERTO RICO DUE TO THE COMBINATION OF THE SEA BREEZE
CONVERGENCE...AVAILABLE MOISTURE AND DIURNAL PROCESSES. A SOUTHEASTERLY
TRADE WIND FLOW WILL PROMOTE WARMER TEMPERATURES ON THURSDAY...WITH
HIGHS IN THE MID 80S ALONG THE HIGHER ELEVATIONS AND IN THE MID TO
UPPER 90S ACROSS THE COASTAL LOCATIONS.

&&

.AVIATION...AT 02Z SHOWERS STILL PERSISTED OVER PUERTO RICO AND WERE
IN THE VCNTY OF TJPS. SOME SHWRS AND MTN OBSCURATIONS MAY PERSIST
BYD 26/08Z AS MOISTURE MOVES NORTH OUT OF THE CARIBBEAN. PTCHY GRND
FOG MAY DEVELOP BTWN 26/04 AND 26/11Z INTERIOR PR. OTHERWISE ALL
STATIONS SHOULD REMAIN VFR THROUGH 26/16Z. AFT 26/16Z SHWRS AND
TSTMS WILL REDEVELOP OVER INTERIOR PR AND SPREAD TO THE NORTH
CENTRAL AND NW COASTS...BRINGING MTN OBSCURATIONS AND MVFR CONDS TO
TJMZ AND TJBQ. USVI AND LEEWARD ISLANDS WILL HAVE PREVAILING VFR.
WINDS BELOW 6 KFT ARE LIGHT SOUTHERLY. WINDS BELOW 22 KFT ARE UP TO
20 KNOTS...BUT VARY GREATLY IN SPEED.

Good morning.


AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SAN JUAN PR
513 AM AST THU MAY 26 2011

.SYNOPSIS...
WEAKENING LOW PRES OVER THE CENTRAL ATLANTIC WITH ASSOCIATED
BROAD TROUGH EXTENDING WEST SOUTHWEST ACROSS THE NORTHEAST
CARIBBEAN WILL CONTINUE TO GRADUALLY DISSIPATE AND PULL FURTHER
NORTH OF THE AREA OVER THE NEXT FEW DAYS...AS HIGH PRESSURE BUILDS
ACROSS THE WEST ATLANTIC. IN DOING SO THE ASSOCIATED BAND OF MOISTURE
CONVERGENCE NOW SAGGING ACROSS THE REGION WILL LIFT FURTHER NORTH
OF THE AREA. IN THE MEANTIME FAIRLY LIGHT AND VARIABLE WINDS WILL
PREVAIL ACROSS THE ENTIRE REGION AT LEAST THROUGH FRIDAY. THEREAFTER...
WINDS WILL SLOWLY BECOME MORE SOUTHEASTERLY AS THE STRONG HIGH
PRESSURE REESTABLISHES ITSELF ACROSS THE NORTH CENTRAL ATLANTIC.
MID TO UPPER LEVEL HIGH PRESSURE RIDGE NOW STRETCHED ACROSS THE
EASTERN CARIBBEAN WILL ERODE SLIGHTLY OVER THE NEXT FEW DAYS...AS
A SHORT WAVE TROUGH NOW CROSSING THE WEST AND SOUTHWEST ATLANTIC...
SLOWLY PULLS EAST NORTHEAST AND JUST NORTH OF THE AREA. THIS WILL
CAUSE THE PREVAILING SOUTHWESTERLY WIND FLOW TO BECOME MORE ZONAL
BY FRIDAY AND INTO THE WEEKEND. IN THE MEANTIME FRAGMENTS OF MID
TO HIGH LEVEL CLOUD DEBRIS WILL CONTINUE TO SPILL OVER INTO THE
LOCAL REGION.

&&

.DISCUSSION...
SATELLITE IMAGERY INDICATED FRAGMENTS OF HIGH LEVEL CLOUDS ASSOCIATED
WITH SUBTROPICAL JETSTREAM SLOWLY PULLING NORTH OF THE AREA...WHILE
A SHEARED OF BAND OF DISSIPATING LOW LEVEL MOISTURE LINGERED ACROSS
THE NORTHEAST CARIBBEAN. MIMIC SATELLITE DERIVED TOTAL PRECIPITABLE
WATER ANALYSIS...AS WELL AS THE GROUND BASED GPS MET DATA...INDICTED
PWAT VALUES STILL LINGERED AROUND 2.20 INCHES. HOWEVER... MODEL GUIDANCE
AS WELL AS PRESENT SATELLITE IMAGERY CONTINUED TO SUGGEST ONLY A SLIGHT
DECREASE IN LAYERED MOISTURE OVER THE NEXT FEW DAYS...WITH VALUES TO
REMAIN BETWEEN 1.77-2.00 INCHES THROUGH THE UPCOMING WEEKEND.

EXPECT THE LIGHT TRADE WINDS TO BRING A FEW EARLY MORNING SHOWERS
ACROSS THE REGION AS WINDS SLOWLY BECOME MORE SOUTHEASTERLY TODAY.
THESE SHOWERS WILL BRING BRIEF PERIODS OF LIGHT TO MODERATE RAINFALL
TO THE EAST COASTAL SECTIONS OF PUERTO RICO AND PARTS OF THE ADJACENT
ISLANDS. HOWEVER...NO SIGNIFICANT RAINFALL AMOUNTS ARE EXPECTED AT
THIS TIME ACROSS THE VIRGIN ISLANDS. THE LIGHT WINDS WILL ALLOW
FOR LOCAL SEA BREEZE VARIATIONS AND THIS COMBINED WITH LOCAL AND
DIURNAL EFFECTS WILL ONCE AGAIN LEAD TO FAVORABLE AFTERNOON CONVECTION
ACROSS PUERTO RICO AND PARTS OF THE VIRGIN ISLANDS. THE AFTERNOON
SHOWERS AND THUNDERSTORMS WILL PRODUCE PERIODS OF MODERATE TO LOCALLY
HEAVY DOWNPOURS. THIS MAY ONCE AGAIN LEAD TO URBAN AND SMALL STREAM
FLOODING IN ISOLATED AREAS.

FOR THE REST OF THE WORK WEEK AND INTO THE WEEKEND...EXPECT SUFFICIENT
LINGERING MOISTURE ACROSS THE REGION AND THE WARM SOUTHERLY WIND FLOW
TO BE SUFFICIENT TO PRODUCE EARLY MORNING AND AFTERNOON CONVECTION
IN ISOLATED SPOTS EACH DAY. THERE SHOULD HOWEVER BE FAIR AMOUNTS OF
SUNSHINE ACROSS THE ISLANDS WITH NO WIDESPREAD OR CONTINUOUS RAINFALL
EXPECTED.

&&

.AVIATION...MOSTLY VFR CONDITIONS WILL CONTINUE ACROSS THE LOCAL ISLANDS
AND AT ALL TAF SITES UNTIL 26/15Z. HOWEVER...BRIEF MVFR CONDITIONS ARE
EXPECTED IN SCATTERED SHOWERS TJSJ THIS MORNING. CLOUDS AND SHOWERS
WILL DEVELOP OVER PUERTO RICO AFTER 26/15Z AND BY 26/17Z EXPECT MOUNTAIN
OBSCURATIONS...SHOWERS AND SCT THUNDERSTORMS IN THE INTERIOR WITH SHOWERS
AND MVFR OR EVEN IFR CONDITIONS POSSIBLE AT TJMZ BETWEEN 26/17Z-26/22Z.
WINDS ARE VERY LIGHT AND VARIABLE FROM THE SURFACE TO AROUND 20K FEET...
BECOMING WESTERLY BUT STILL LIGHT ALOFT.

CARIBBEAN DURING THE NEXT FEW DAYS. A MOIST AND UNSTABLE ATMOSPHERE
WILL CONTINUE ACROSS THE REGION THROUGH AT LEAST MONDAY.

&&

.DISCUSSION...HIGH CLOUDS...AND VERY HUMID AIR PREVAILED ACROSS THE
LOCAL AREA THIS AFTERNOON. MOISTURE ACROSS THE LOCAL AREA
CONTINUES HIGH...AND THIS SCENARIO IS NOT EXPECTED TO CHANGE IN
THE NEAR FUTURE. A SOUTHEAST TO SOUTH WIND FLOW AT THE SURFACE

DEVELOPMENT OF SHOWERS AND THUNDERSTORMS ACROSS THE NORTHERN HALF
OF PUERTO RICO. A MORE EASTERLY WIND FLOW IS EXPECTED
MONDAY. THIS WILL CREATE LESS HUMID CONDITIONS ACROSS THE REGION
...AND SHOWERS DEVELOPMENT IS EXPECTED ACROSS THE WESTERN INTERIOR
AND WEST SECTIONS OF PUERTO RICO.

IN THE LONG TERM...GFS COMPUTER MODEL IS FORECASTING THE
DEVELOPMENT OF A LOW PRESSURE SYSTEM ACROSS THE WESTERN
CARIBBEAN...WITH AMPLE MOISTURE ASSOCIATED WITH IT. IF THIS
VERIFY...CONDITIONS WILL CONTINUE WET DURING THE BEGINNING OF NEXT
MONTH. STAY TUNED.
