I was gone,but found the updated discussion from the San Juan NWS so here it is.

AREA FORECAST DISCUSSION...UPDATED
NATIONAL WEATHER SERVICE SAN JUAN PR
935 PM AST WED JUL 29 2009

.SYNOPSIS...SUBTROPICAL RIDGE WILL CONTINUE TO SUPPORT MODERATE TO FRESH
TRADE WINDS ACROSS THE REGION. TROPICAL WAVE ALONG 61W WILL MOVE
ACROSS THE LOCAL CARIBBEAN WATERS TOMORROW. ANOTHER TROPICAL WAVE
IS EXPECTED FOR SUNDAY.

&&

.DISCUSSION...ALTHOUGH BULK OF THE MOISTURE ASSOCIATED WITH
TROPICAL WAVE IS EXPECTED TO REMAIN ACROSS CARIBBEAN WATERS...SCT
TO NMRS SHOWERS SHOULD DEVELOP ACROSS THE ISLANDS TOMORROW IN THE
EAST IN THE MORNING AND THEN IN THE WEST IN THE AFTERNOON. LOCALIZED
FLOODING IS POSSIBLE IN AREAS OF HEAVIER RAIN. HAVE ADJUSTED
POPS/SKY CVR/QPF UPWARD FROM PREVIOUS FCST.

A SHARP DROP IN PWAT VALUES AND A STRONG CAP/SUBSIDENCE INVERSION IS
FCST BY THE GFS ON SAT AHEAD OF NEXT TROPICAL WAVE ANALYZED ALONG
30W WITH THE WAVE PASSAGE FCST ON SUN. SO IT LOOKS LIKE SAT WILL
BE THE DRIEST DAY OF THE NEXT SEVERAL AND SUN THE WETTEST.
OTHERWISE...THE EXTENDED FCST WILL BE DOMINATED BY EASTERLY FLOW
WITH MODEST MOISTURE AND NO SIGNIFICANT WEATHER FEATURES. A
CLIMATOLOGICAL FCST SHOULD WORK BEST DURING MOST OF THE EXTENDED
PERIODS. HOWEVER...ADJUSMENTS WERE MADE TO THE FIRST AND SECOND
PERIODS ONLY.

&&

.AVIATION...PREVAILING VFR CONDITIONS WILL CONTINUE ACROSS ALL LOCAL
TAF SITES UNTIL 30/1000Z. TROPICAL WAVE WILL PASS MAINLY SOUTH OF
THE REGION LATE TONIGHT AND TOMORROW PRODUCING BRIEF PERIODS OF MVFR
CONDITIONS IN PASSING SHRA ACROSS TKPK...TNCM...TISX AND TIST AFTER
30/1000Z. AFTER 30/1600Z...SCATTERED SHOWERS AND ISOLATED
THUNDERSTORMS WITH MOUNTAIN OBSCURATIONS WILL BEGIN TO DEVELOP
ACROSS CENTRAL AND WESTERN PUERTO RICO WITH PERIODS OF MVFR
CONDITIONS ACROSS TJPS... TJMZ AND TJBQ UNTIL AT LEAST 30/2200Z.

&&

.MARINE...A WIND SURGE BEHIND A TROPICAL WAVE ALONG 60W THIS
EVENING WILL CAUSE E WINDS TO GUST UP TO 30KT ACROSS LOCAL
CARIBBEAN WATERS TOMORROW. SEAS OF 7-8 FEET ARE EXPECTED AS A
RESULT ESPECIALLY ACROSS UNPROTECTED WATERS. SEE MARINE WEATHER
MESSAGE/MWWSJU/ FOR MORE DETAILS.

Now I say good night to all.

[cycloneye]

Good morning to my fellow Caribbean friends.Scattered showers for today as a wave moves thru the area.

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SAN JUAN PR
411 AM AST THU JUL 30 2009

.SYNOPSIS...
TROPICAL WAVE OVER THE EASTERN CARIBBEAN THIS MORNING WILL MOVE
ACROSS THE LOCAL CARIBBEAN WATERS LATER TODAY. THIS WAVE IS
EXPECTED TO MOVE WEST AND AWAY FROM THE LOCAL AREA BETWEEN TONIGHT
AND FRIDAY. AFTER THIS WAVE MOVE AWAY FROM THE REGION A HIGH
PRESSURE WILL BUILD OVER THE LOCAL AREA.

&&

.DISCUSSION...A TROPICAL WAVE NOW LOCATED OVER THE EASTERN
CARIBBEAN WATERS WILL CONTINUE TO MOVE WEST TODAY...INCREASING THE
LOW LEVEL MOISTURE ACROSS THE LOCAL FORECAST AREA. THE BULK OF THE
MOISTURE WILL COINCIDE WITH THE PEAK OF DIURNAL HEATING...
THEREFORE SHOWERS AND THUNDERSTORMS ARE EXPECTED TO DEVELOP OVER
THE WESTERN AND INTERIOR SECTIONS OF PUERTO RICO. ALSO THE EXTREME
SOUTHWEST PORTIONS OF PUERTO RICO COULD EXPERIENCE SOME SHOWERS AS
STEERING WINDS WILL BE FROM THE EAST NORTHEAST. THIS WAVE IS
EXPECTED TO MOVE AWAY FROM THE LOCAL AREA LATER TONIGHT. ASSOCIATED
MOISTURE TO THIS WAVE WILL LINGER FOR THE NEXT FEW DAYS TO PRODUCE
AFTERNOON SHOWERS OVER THE INTERIOR AND WESTERN PORTIONS OF PUERTO
RICO ON FRIDAY AND SATURDAY.

&&

.AVIATION...EXPECT PREVAILING VFR CONDITIONS ACROSS THE LOCAL
ISLANDS AND AT ALL LOCAL TAF SITES THROUGH TONIGHT. HOWEVER...BRIEF
MVFR CONDITIONS AND LOCAL MOUNTAIN OBSCURATIONS ARE EXPECTED IN
SCATTERED SHRA AND ISOLATED TSRA...ESPECIALLY OVER THE CENTRAL AND
WESTERN INTERIOR AND WEST SECTIONS OF PUERTO RICO BETWEEN 16Z AND
21Z. IN ADDITION...SURFACE WIND GUSTS OF 25 TO 30 KNOTS ARE
POSSIBLE...ESPECIALLY NEAR ANY SHRA OR TSRA.

&&

.MARINE...MODERATE TO FRESH WINDS WITH HIGHER GUSTS WILL PREVAIL
TODAY AS A TROPICAL WAVE MOVE ACROSS THE CARIBBEAN WATERS. THIS
WILL GENERATE CHOPPY SEAS ACROSS THE ATLANTIC AND CARIBBEAN
WATERS. THEREFORE SMALL CRAFT ADVISORIES WERE ISSUED FOR THE OFF
SHORE ATLANTIC AND CARIBBEAN WATERS.

[Gustywind]

Hi everybody, hope the very best for you enjoying the holidays! As Cycloneye mentionned it before scattered showers are in store for today in most of the islands...

.UPDATE...A BAND OF SHOWERS NORTH OF THE APEX OF THE TROPICAL WAVE
NICKED THE NORTH CENTRAL AND NORTHEAST COASTAL SECTIONS OF PUERTO
RICO AFTER SUNRISE THIS MORNING AFTER LEAVING FOUR ONE HUNDREDTHS
OF AN INCH OF RAIN IN SAINT THOMAS. THE BAND THEN MOVED WEST
NORTHWEST INTO THE ATLANTIC WHERE...AS OF 11 AM...IT WAS BREAKING
UP. ALTHOUGH STREAMERS HAVE DEVELOPED DOWNWIND FROM ALL OF THE

EXCEPT IN THE SOUTHWEST...THE REST OF THE FORECAST AREA IS MOSTLY
SUNNY. SHOWERS AND ISOLATED THUNDERSTORMS ARE EXPECTED TO DEVELOP

...IF ANY...SHOWERS WILL BE OBSERVED IN THE U.S. VIRGIN

WARM AND A NUMBER OF STATIONS ARE APPROACHING OR HAVE ALREADY
