AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SAN JUAN PR
1217 PM AST MON SEP 8 2003
UPDATE...
SUBSTITUTED WIDESPREAD SCATTERED SHOWERS TO ISOLATED...FORECASTING
SCATTERED SHOWERS AND ISOLATED THUNDERSTORMS FOR PARTS OF THE
INTERIOR...SAN JUAN METRO AREA AND WEST SECTIONS OF PUERTO RICO FOR
THIS AFTERNOON. ALSO...DROP A FOOT ON THE COASTAL DUE TO LOCAL
OBSERVATIONS. BUT...SEAS ARE EXPECTED TO GRADUALLY INCREASE THIS
WEEKEND AS NORTHEAST SWELLS GENERATED BY HURRICANE ISABEL WILL BEGIN
TO ARRIVE TO OUR NORTH AND EAST COASTAL WATERS OF THE LOCAL
ISLANDS./ROCHE
500 AM DISCUSSION...
THE UPPER LEVEL LOW NEAR 19 NORTH AND 60 WEST AND HURRICANE ISABEL
AT 18.9 NORTH AND 45.2 WEST ARE THE TWO VERY PROMINENT FEATURES ON
THIS MORNINGS SATELLITE IMAGES. THE FIRST HAS ENHANCED CONVECTIVE
ACTIVITY TO OUR EAST AT THIS TIME WHILE HURRICANE ISABEL...EVEN WITH
THE UNCERTAINTY OF TRACK THAT CONTINUES DUE TO THE POSSIBILITY THAT
IT COULD BEGIN TO TRACK WEST-SOUTHWEST AFTER 36 HOURS...WILL
CERTAINLY AFFECT THE WIND...MOISTURE AND OCEAN SWELL BEGINNING
PERHAPS AS EARLY AS THURSDAY WHEN WINDS BEGIN TO SHIFT MORE
NORTHERLY AHEAD OF ISABEL. THE REAL DIFFICULTY IS KNOWING HOW MUCH
THE HURRICANE WILL AFFECT THE AREA.
CURRENTLY THE HURRICANE CENTER HAS THE CENTER A LITTLE OVER 125 NM
FROM THE NORTHEAST CORNER OF OUR FORECAST AREA AT 120
HOURS...ROUGHLY SUNDAY AT 9Z...AT 21 NORTH 63 WEST...PLACING
TROPICAL STORM FORCE WINDS OUTSIDE THE FORECAST AREA AT THAT TIME.
THE GFS MODEL PLACES ISABEL AT 19.4 NORTH 62.5 WEST...WHICH WOULD
SET TROPICAL STORM FORCE WINDS INSIDE THE AREA BY SUNDAY...BUT NOT
BY SATURDAY. EXPECT THAT ISABEL WILL PASS NO FARTHER AWAY AT THIS
TIME THAN THE FORECAST TRACK BY THE NATIONAL HURRICANE CENTER...BUT
NOT CLOSER THAN THE GFS...THEREFORE HAVE LEFT THE MENTION OF
TROPICAL STORM FORCE WINDS OUT OF THE SATURDAY FORECAST AT THIS TIME.
A WIDE MARGIN OF ERROR IS POSSIBLE FOR THIS HURRICANE...SO THIS
FORECAST...WHICH NECESSARILY MUST BE SPECIFIC AS TO TIME AND PLACE
OF PASSAGE...DOES NOT RULE OUT THE POSSIBILITY THAT ISABEL COULD
PASS OVER PUERTO RICO SOME TIME AFTER SATURDAY.
IN THE NEAR TERM EXPECT THAT ONLY FAIR MOISTURE WILL CONTINUE TODAY
THROUGH WEDNESDAY MORNING AT LOWER LEVELS AND THAT MOISTURE WILL BE
WEAK AT 700 MB AND ABOVE. ALSO EXPECT THAT THE UPPER LEVEL LOW WILL
NOT SUPPLY MUCH DIVERGENCE ALOFT AT THE SAME TIME. THUS WILL KEEP
POPS TYPICAL FOR DAYTIME PUERTO RICO AND ENVIRONS TODAY AND TOMORROW
AND NO BETTER THAN SCATTERED TONIGHT AND TOMORROW MORNING. ON
THURSDAY WINDS BEGIN TO TURN NORTHERLY WHILE REMAINING LIGHT TO
MODERATE DUE TO THE ADVANCE EFFECTS OF HURRICANE ISABEL. THIS WILL
CHANGE THE NORMAL DISTRIBUTION OF RAINFALL A SECOND TIME THIS MONTH
AND RE-DIRECT DAYTIME SHOWERS MAINLY TOWARD THE SOUTH OF THE
ISLAND...WITH SOME STREAMERS HANGING OFF OF ST THOMAS AND ST CROIX
TOWARD THE SOUTHWEST. FRIDAY THROUGH SUNDAY WILL DEPEND MUCH ON THE
ACTUAL POSITION OF ISABEL BUT HAVE SHOWERS INCREASING IN THE LOWER
LEVEL CONVERGENCE AREA AHEAD OF THE HURRICANE THEN. WILL CONSIDER
THAT ISABEL MAY BE NEAR PUERTO RICO ON MONDAY...OR SOMEWHAT NORTH
WITH A TRAILING TAIL THAT MAY SWEEP THE AREA WITH NUMEROUS SHOWERS.
REGARDLESS OF THE TRACK...SWELL SHOULD BEGIN TO ARRIVE IN OUR MARINE
AREA OF RESPONSIBILITY BY FRIDAY AND BUILD THROUGH SUNDAY...POSSIBLY
TO LEVELS WHICH WILL EXCEED THE WAVE ACTION GENERATED BY FABIAN.
