Area forecast discussion, Apr 5, 2:41 PM AST, 2 hours 3 minutes before
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE SAN JUAN PR 241 PM AST SUN APR 5 2015 .SYNOPSIS...SURFACE HIGH PRESSURE ACROSS THE CENTRAL ATLANTIC WILL CONTINUE TO PRODUCE MODERATE TRADE WINDS FROM THE EAST TO EAST NORTHEAST ACROSS THE LOCAL AREA FOR THE NEXT SEVERAL DAYS. THESE WINDS WILL CONTINUE TO TRANSPORT PATCHES OF LOW LEVEL MOISTURE ACROSS THE REGION. UPPER LEVEL TROUGH WILL DEVELOP ACROSS THE WESTERN ATLANTIC MID WEEK. && .DISCUSSION...JUST LIKE IT WAS EXPECTED...SHOWERS DEVELOPED ACROSS THE INTERIOR AND WESTERN SECTIONS OF PR IN THE AFTERNOON HOURS...A FEW SHOWERS ALSO DEVELOPED ACROSS PORTIONS OF THE SAN JUAN METRO AREA AND ACROSS THE USVI. SOME OF THE SHOWERS ARE MOVING SLOWLY SO THEY ARE STAYING OVER ANY ONE POINT FOR SEVERAL MINUTES...CAUSING SOME PONDING OF WATER IN LOW LYING AREAS AND ROADWAYS. THIS SHOWER ACTIVITY IS EXPECTED TO END NEAR SUNSET WITH TOTALS GENERALLY BETWEEN A HALF IN CH AND TWO INCHES. OVERNIGHT WE CAN EXPECT THE USUAL PASSING SHOWERS ACROSS THE WATERS...EASTERN AND NORTHERN PR AND ACROSS THE USVI. AS THE UPPER TROUGH CONTINUES TO MOVE OUT TO THE EAST WE CAN EXPECT SCATTERED SHOWERS AFFECTING PUERTO RICO IN THE AFTERNOON BUT THE CHANCES OF THUNDERSTORMS ARE VERY LIMITED AS WE ARE IN THE SUBSIDENT SIDE OF THE UPPER TROUGH. UP UNTIL THURSDAY WE CAN EXPECT A SIMILAR WEATHER PATTERN. THEN ANOTHER UPPER TROUGH MOVES INTO THE WESTERN CARIBBEAN ON THURSDAY. THIS SHOULD CAUSE INSTABILITY TO INCREASE ACROSS THE LOCAL AREA. LATEST GUIDANCE SHOWS A SLIGHT INCREASE INT THETA-E ON THURSDAY INTO SATURDAY...BUT IT DOESN'T LOOK IMPRESSIVE AT THE MOMENT. THE AVAILABLE MOISTURE IS EXPECTED TO BE CONSTANT FOR THE NEXT SEVERAL DAYS WITH PRECIPITABLE WATER VALUES AT AROUND 1.4 INCHES...HOWEVER TOWARDS THE END OF THE WEEK...THE LONG RANGE MODELS HAVE MOISTURE INCREASING QUITE A BIT WITH PRECIPITABLE WATER VALUES AS HIGH AS 1.75 INCHES ON SATURDAY AFTERNOON. && .AVIATION...SHRA/ISOLD TSRA IN WEST PR THIS AFT TO DECREASE LATE... SCT SHRA ELSEWHERE. SOME OBSCD MTNS AND MVFR IN SHRA/TSRA POSBL AT TJMZ. VFR TONITE XCP PSBL MVFR IN FEW SHRA...THEN VFR AND SCT SHRA ACRS ISLANDS MON AND SLIM CHC OF MVFR.

THE NEARSHORE BUOY TO THE NORTH OF SAN JUAN HAS BEEN REPORTING AROUND 5 FOOT SEAS AND THE OFFSHORE BUOY 40143 IS REPORTING SEAS CLOSE TO 6 FEET BUT NOT QUITE 6.
