AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SAN JUAN PR
1135 AM AST SAT APR 27 2013

.UPDATE...ISOLATED TO SCATTERED SHOWERS HAVE BEEN MOVING IN FROM
THE NORTHEAST AND SLOWLY MOVING ACROSS THE LOCAL ISLANDS. PASSING
SHOWERS ARE NOW AFFECTING PUERTO RICO AND THE U.S. VIRGIN ISLANDS
BUT THE SHOWERS ARE MOSTLY LIGHT...ONLY A FEW MODERATE SHOWERS. WIND
HAS PREVAILED FROM THE NORTHEAST EXCEPT NEAR THE SHOWERS WHERE THE
LOCAL AIRPORTS HAVE REPORTED LIGHT AND VARIABLE WINDS.

ISOLATED TO SCATTERED SHOWERS ARE EXPECTED TO CONTINUE AT LEAST
INTO THE EARLY HOURS OF THE AFTERNOON WITH SCATTERED SHOWERS
DEVELOPING ACROSS SOUTHERN PR. ONE OR TWO THUNDERSTORMS ARE
POSSIBLE AS WELL. 27/12Z SOUNDING INDICATED HIGHER MOISTURE AND
ENOUGH INSTABILITY TO CAUSE THUNDERSTORMS. GIVEN THE WIND FLOW AND
THE SEA BREEZE CONVERGENCE EXPECTED ACROSS THE SOUTHERN SECTIONS
OF PUERTO RICO...SOUTHERN PR IS WHERE THUNDERSTORMS WOULD BE
EXPECTED.

&&

.AVIATION...BRIEF MVFR CONDITIONS ARE POSSIBLE TODAY AS PASSING
SHOWERS ARE EXPECTED ACROSS PR AND THE USVI...HOWEVER THE
CONDITIONS ARE EXPECTED TO BE MOSTLY VFR. MODERATE SHRA/TSRA ARE
POSSIBLE IN AND AROUND TJPS AND MAYBE EVEN TJMZ. CONDITIONS
EXPECTED TO IMPROVE TONIGHT WITH WINDS DECREASING.

&&

.MARINE...NO SIGNIFICANT CHANGES FROM THE PREVIOUS DISCUSSION.
SEAS CONTINUE TO BE HAZARDOUS AND ARE EXPECTED TO CONTINUE
HAZARDOUS THROUGH THE DAY...PEAKING ON SUNDAY.

&&

.PREV DISCUSSION... /ISSUED 505 AM AST SAT APR 27 2013/

SYNOPSIS...WEAKENING UPPER TROUGH EAST OF THE LESSER ANTILLES WILL
CONTINUE TO FILL AND PULL AWAY FROM THE REGION LEAVING A HIGH ZONAL
FLOW ACROSS THE REGION AT LEAST THROUGH EARLY NEXT WEEK.  LOW LEVEL
INVERTED TROUGH ACROSS THE REGION WILL ALSO WEAKEN TODAY IN RESPONSE
TO HIGH PRESSURE RIDGE BUILDING ACROSS THE WEST AND SOUTHWEST ATLANTIC.
THIS WILL CONTINUE TO INDUCE A LIGHT TO MODERATE NORTHEAST WIND FLOW
WHICH WILL BECOME MORE EASTERLY BY SUNDAY AN INTO EARLY NEXT WEEK...AS
HIGH PRESSURE RIDGE BUILDS NORTH OF THE AREA.

DISCUSSION...MOSTLY FAIR WEATHER SKIES AND SUNNY SKIES ON TAB FOR
TODAY AND THROUGH MOST OF THE WEEKEND AS UPPER LEVEL CONVERGENCE AND
SUBSIDENCE ALOFT WILL LIMIT/SUPPRESS MOST OF THE DAYTIME CONVECTION.
THIS OVERALL WEATHER SCENARIO IS TO CONTINUE INTO NEXT WEEK WITH
BRIEF PERIODS OF EARLY MORNING PASSING SHOWERS FOLLOWED BY SCATTERED
TO ISOLATED AFTERNOON CONVECTION EXPECTED TO OCCUR MAINLY OVER THE
INTERIOR AND WEST SECTIONS OF PUERTO RICO. LOCAL AND DIURNAL EFFECTS
WILL BE SUFFICIENT TO AID IN THE DEVELOPMENT OF SOME SHOWERS WITH
SLIGHT CHANCE OF AN ISOLATED AFTERNOON THUNDERSTORMS IN THE WEST.
RAINFALL AMOUNTS WILL BE MINIMAL IN MOST AREAS EXCEPT FOR THE WEST
INTERIOR OF PUERTO RICO WHERE ISOLATED THUNDERSTORMS MAY PRODUCE
PERIODS OF MODERATE TO LOCALLY HEAVY DOWNPOURS FOR A SHORT DURATION.
BY THE MIDDLE OF NEXT WEEK AND INTO THE FOLLOWING WEEKEND ...ALL
MODELS CONTINUE TO SUGGEST A MUCH WETTER MOISTURE PATTERN WITH LAYERED
PWAT VALUES INCREASING UP TO 2.00 INCHES OR MORE AS WE TRANSITION
INTO THE MONTH OF MAY...WHEN CONDITIONS NORMALLY START TO BECOME
HOT AND HUMID WITH BETTER CHANCE FOR PERIODS OF MORE TYPICAL SUMMER
TYPE CONVECTION EACH AFTERNOON.

AVIATION...MOSTLY VFR CONDITIONS EXPECTED ACROSS THE LOCAL FLYING
AREA FOR THE NEXT 24 HOURS. HOWEVER...BRIEF PERIODS OF MVFR
CONDITIONS ARE POSSIBLE ACROSS TIST AND TJSJ UNTIL AT LEAST 17/16Z
AND ACROSS TJPS BETWEEN 27/18Z-22Z DUE TO SHRA/TSRA DEVELOPMENT.
SURFACE WINDS WILL BE FROM THE NORTHEAST AT LESS THAN 10 KT...
INCREASING TO 10-15KT AFTER 27/12Z.

MARINE...NE SWELL ACTION HAS NOW ARRIVED AT THE OUTER BUOYS NORTH
OF THE AREA WITH THE NORTHEAST BUOY 40144 ALREADY REGISTERING SEAS
OF 9 FEET AT 16 TO 17 SECS...WHILE 41043 SHOWED INCREASING SEAS
OF 7 AROUND 11 SECS. THE SAN JUAN BUOY SHOWED STEADILY INCREASING
SEAS NOW AROUND 5 FEET AT 10 SECS. EXPECT THE SWELL ACTION TO SPREAD
ACROSS THE ATLANTIC AND LOCAL PASSAGES AND PEAK ON SUNDAY.
