WEATHER SUMMARY FOR PUERTO RICO
NATIONAL WEATHER SERVICE SAN JUAN PR
500 PM AST WED APR 16 2014

SKIES WERE MOSTLY SUNNY TO PARTLY CLOUDY OVER THE LOCAL ISLANDS
AND SURROUNDING WATERS TODAY. CLOUD DEVELOPED ACROSS PARTS OF THE
INTERIOR...WEST AND THE SOUTHERN SLOPES OF THE ISLAND. THIS LEAD
TO PERIODS OF MODERATE TO LOCALLY HEAVY RAINFALL AND EVENTUALLY
CAUSED MINOR PONDING OF WATER ON ROADWAYS AND HAZARDOUS DRIVING
CONDITIONS IN SOME AREAS. OVERALL... AFTERNOON HIGH TEMPERATURES
WERE IN THE MID 70S TO NEAR 80 DEGREES IN HIGHER ELEVATIONS AND
MID TO HIGH 80S ALONG THE COASTAL AREAS. EXCEPT FOR LOCAL SEA
BREEZE VARIATIONS WINDS WERE FROM THE EAST AT 10 TO 15 MPH.

AN UPPER LEVEL HIGH PRESSURE RIDGE WILL BUILD OVER THE REGION
THROUGH THURSDAY AND HOLD THROUGH THE END OF THE WEEK. IN ADDITION...
SURFACE HIGH PRESSURE WILL CONTINUE TO BUILD NORTH OF THE AREA
THROUGH THE END OF THE WEEK. THIS SCENARIO WILL CAUSE THE LOCAL
PRESSURE GRADIENT TO TIGHTEN AND LEAD TO AN INCREASE IN THE EASTERLY
TRADE WINDS THROUGH THE END OF THE WEEK. BETTER MOISTURE TRANSPORT
CAN BE EXPECTED OVER THE NEXT FEW DAYS...THEREFORE EARLY MORNING
PASSING SHOWERS WILL AFFECT MAINLY THE EAST COASTAL SECTIONS OF
THE ISLANDS. THIS COMBINED WITH DIURNAL HEATING AND SEA BREEZE
CONVERGENCE WILL LEAD TO AFTERNOON SHOWER DEVELOPMENT EACH DAY
PARTICULARLY ACROSS PARTS OF THE INTERIOR SECTIONS OF THE ISLAND.

ACROSS THE COASTAL WATERS...EASTERLY WINDS UP TO 15 KNOTS AND
SEAS UP TO 5 FEET ARE EXPECTED OVERNIGHT. WINDS AND SEAS WILL
INCREASE BY THURSDAY MORNING AND FRIDAY IN RESPONSE TO THE HIGH
PRESSURE BUILDING NORTH OF THE AREA AND THE INCREASING EASTERLY
TRADE WINDS. AS A RESULT SMALL CRAFT ADVISORY CONDITIONS WILL BE
REQUIRED FOR SOME AREAS.
