AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SAN JUAN PR
309 PM AST FRI NOV 21 2014

.SYNOPSIS...AT UPPER LEVELS...A TUTT LOW ABOUT 250 MILES SOUTH OF

ISLANDS BY SATURDAY NIGHT. HIGH PRESSURE WILL CONTINUE OVER THE
CARIBBEAN. ANOTHER TROUGH WILL EXTEND INTO THE EASTERN CARIBBEAN
MID WEEK NEXT WEEK.

TO NORTH OF HISPANIOLA AS A LOW CUTS OFF ABOUT 1300 MILES EAST
NORTHEAST OF SAN JUAN PUERTO RICO ON TUESDAY.

AT LOWER LEVELS...HIGH PRESSURE IN THE CENTRAL ATLANTIC FADES
TONIGHT AND SATURDAY...BUT A HIGH FRESH OUT OF THE EASTERN UNITED
STATES WILL MOVE INTO THE WESTERN ATLANTIC SATURDAY NIGHT AND
STRENGTHEN AS IT MOVES EAST NORTHEAST INTO THE CENTRAL ATLANTIC WEDNESDAY.

&&

.DISCUSSION...THE GFS IS BECOMING WETTER TONIGHT AS IT FORECASTS
PRECIPITABLE WATER TO RISE CLOSE TO 2.2 INCHES BY 22/06Z TONIGHT.
NEVERTHELESS UPPER LEVEL DYNAMICS ARE STILL VERY WEAK TO MISSING
AFTER TONIGHT. A FEW SHOWERS MOVED ACROSS THE AREA TODAY AND MOST
OF EASTERN QUARTER OF PUERTO RICO...THE U.S. VIRGIN
ISLANDS...CULEBRA AND VIEQUES RECEIVED RAIN. SHOWERS WERE ALSO
FALLING IN SOUTHWEST PUERTO RICO AT 3 PM AST. EXPECT SHOWERS TO
INCREASE CONSIDERABLY TONIGHT...ESPECIALLY OVER EASTERN PUERTO
RICO AND THE U.S. VIRGIN ISLANDS...BUT WESTERN PUERTO RICO STILL
HAS ONLY A SMALL CHANCE OF SHOWERS AFTER SUNSET. SHOWERS THERE
WILL INCREASE ON SATURDAY. SHOWERS WILL TAPER OFF ON SUNDAY
MORNING WITH BETTER WEATHER ON SUNDAY AFTERNOON. ALTHOUGH
PRECIPITABLE WATER DROPS BELOW 1.3 INCHES SEVERAL TIMES NEXT WEEK...
THE SCATTERED TRADE WIND SHOWERS SO TYPICAL OF NOVEMBER SHOULD BE
EXPECTED TO CONTINUE IN THE USUAL PLACES IN EASTERN PUERTO
RICO...WITH A CHANCE OF SHOWERS IN THE WEST IN THE AFTERNOON.
TEMPERATURES SHOULD BECOME A LITTLE COOLER AND HOLD CLOSE TO NORMAL.

SHRA/TSRA ACTIVITY ACROSS THE LEEWARD ISLANDS SPREADING THROUGH THE
USVI AND EASTERN PR WITH VCTS/VCSH LIKELY FOR MOST OF THE LOCAL
TERMINALS AND POSSIBLY AFFECTING THE TERMINALS FOR BRIEF PERIODS.
THIS ACTIVITY MAY CAUSE BRIEF PERIODS OF MVFR CONDS. EASTERLY SFC
WINDS 10 TO 20 KTS WITH HIGHER GUSTS.

&&

.MARINE...HAVE TAKEN SEAS DOWN FOR A LITTLE WHILE OVER ALL OF THE
AREA AS SEAS OBSERVED ARE NOT MEASURING UP TO THE MODEL FORECASTS
AT THIS TIME. SEAS WILL STILL INCREASE FROM THEIR PRESENT STATE
AND SMALL CRAFT ADVISORY CONDITIONS WILL SPREAD OVER MORE THAN
JUST THE ATLANTIC WATERS AFTER TONIGHT DUE TO AN INCREASE IN THE
TRADE WINDS AS THE HIGH INCREASES.
