AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SAN JUAN PR
253 PM AST SUN MAR 15 2015

.SYNOPSIS...AT UPPER LEVELS...FLOW WILL BECOME MORE WESTERLY AS AN
UPPER LEVEL TROUGH IN THE MID LATITUDES PASSES TO THE NORTH. THE
TAIL OF A WEAK JET WILL MOVE OVERHEAD ON TUESDAY AND FLOW WILL
BECOME MORE NORTHWEST BEHIND IT. THE RIDGE OVER THE WESTERN AND
CENTRAL CARIBBEAN WILL PASS OVER THE LOCAL AREA EARLY NEXT WEEK.

AT MID LEVELS...A RIDGE EXTENDING EAST OVER THE GREATER ANTILLES
WILL RETREAT TO THE WEST AS A LONG WAVE TROUGH MOVES TOWARD THE
CENTRAL ATLANTIC NORTH OF THE LOCAL AREA MONDAY AND TUESDAY. HIGH
PRESSURE WILL MOVE TOWARD AND OVER THE LOCAL AREA EARLY NEXT WEEK.

AT LOWER LEVELS...HIGH PRESSURE WILL MOVE INTO THE EASTERN
ATLANTIC CAUSING THE TRADE WINDS TO FLAG AS A LOW PRESSURE MOVES
OFFSHORE IN THE NEW ENGLAND STATES. THE ASSOCIATED COLD FRONT WILL
APPROACH PUERTO RICO AND THE U.S. VIRGIN ISLANDS AS CLOSE AS THE
20 DEGREE NORTH LATITUDE LINE ON WEDNESDAY. THE BEST MOISTURE WILL
OCCUR MONDAY OF NEXT WEEK WHEN PATCHES OF MOISTURE FROM THE FRONT
THAT APPROACHED ON WEDNESDAY BREAK AWAY AND RETURN TO THE AREA IN
NORTHEAST FLOW.

&&

.DISCUSSION...A FEW SHOWERS FORMED IN THE DOWN STREAM FLOW OF
SAINT THOMAS AND MOVED OVER THE NORTHEAST COASTLINE OF PUERTO
RICO. OTHERWISE THERE HAS NOT BEEN ENOUGH MOISTURE TO ALLOW
SIGNIFICANT SHOWERS TO FORM OVER THE REST OF THE U.S. VIRGIN
ISLANDS OR PUERTO RICO INCLUDING VIEQUES. BOTH THE GFS AND THE
NAM5 MODEL SHOW ADDITIONAL MOISTURE AND SHOWERS MOVING INTO THE
FORECAST AREA LATER TONIGHT FROM THE EAST SOUTHEAST AND PUSHING
ACROSS SAINT CROIX AND INTO EASTERN PUERTO RICO WITH SCATTERED
SHOWERS EXPECTED BY MONDAY MORNING. BETTER SHOWERS ARE DEPICTED
FOR MONDAY AFTERNOON...AND THIS MAINLY OVER THE CORDILLERA CENTRAL
IN WESTERN PUERTO RICO. THERE APPEARS TO BE LITTLE CHANGE IN THE
SURFACE WINDS MONDAY THROUGH FRIDAY OF THIS WEEK AND ONLY PATCHY
PASSING SHOWERS BEFORE MONDAY OF NEXT WEEK.

&&

.AVIATION...MAINLY VFR CONDITIONS FOR THE NEXT 24 HOURS ACROSS ALL
TAF SITES. -SHRA IN THE VICINITY OF TJMZ/TJSJ THRU AT LEAST 22Z.
FEW CLOUDS TONIGHT ACROSS THE USVI AND PR...WITH SCT/BKN CIGS AT

A LITTLE ABOVE 6 FEET WITH AN 11 SECOND DOMINANT PERIOD. EXPECT
THE SEAS TO CONTINUE TO RISE LATE THIS AFTERNOON AND EARLY THIS
EVENING IN ZONE 712 OF OUR ATLANTIC NEAR SHORE WATERS AS THE PEAK
IN SWELL SURGES INTO THE AREA. SEAS WILL THEN SUBSIDE THROUGH
TUESDAY WITH A WEAK SURGE ON WEDNESDAY AND A STRONGER SURGE ON
