.UPDATE...SATELLITE IMAGES SHOW A DRAMATIC INCREASE IN CLOUD
COVERAGE TO THE NORTH OF THE AREA AFTER 15/20Z. RADAR ALSO SHOWED
SOME SHOWERS MOVING IN ON THE NORTHEAST FLOW. TWO HUNDREDTHS OF AN
INCH WERE MEASURED AT THE AIRPORT IN SAN JUAN BETWEEN
14/21-22Z...A FEW MORE MAY BE MEASURED LATER TONIGHT WITH SIMILAR AMOUNTS.
16/00Z SOUNDING SHOWED SATURATED LAYER FROM ABOUT 3200 FEET TO
ALMOST 7000 FEET...JUST ENOUGH TO GENERATE SHALLOW SHOWERS. TOPS
OVER WATER WERE MEASURING 12-14 KFT.

&&

.DISCUSSION...MOST GRIDS WERE IN GOOD SHAPE...INCLUDING WAVE
HEIGHTS...SHOWING 8 TO 9 FEET EVEN AS CLOSE AS BUOY 41053. HIGH
SURF ADVISORY MUST THEREFORE BE CONTINUED AND MAY NEED TO BE
EXTENDED LATER TONIGHT TO INCLUDE THE MORNING HOURS ON MONDAY.
VERY ROUGH SEAS AND STRONG RIP CURRENTS ARE EXPECTED TO CONTINUE. WINDS
ALSO WILL BE SLOW TO SUBSIDE AS HIGH PRESSURE NORTH OF THE MONA
CHANNEL AND EAST OF GEORGIA HAS MAINTAINED A CENTRAL PRESSURE OF
1028 MB. WINDS GUSTS ARE LESS THAN YESTERDAY HOWEVER...WITH THE
MOST VULNERABLE AREAS RUNNING 20 TO 30 KNOTS. SHALLOW MOISTURE
TONIGHT IS INTERRUPTED DURING THE DAY TOMORROW ONLY TO RETURN
MONDAY NIGHT AGAIN WITH A FEW SHOWERS. EXPECT VERY FEW SHOWERS
DURING THE DAY MONDAY AND MOSTLY SUNNY SKIES AFTER MORNING BURN
OFF. TUESDAY MORNING APPEARS A LITTLE WETTER AND HAVE ADJUSTED
POPS UP SLIGHTLY THEN.

THESE SHALLOW PATCHES OF MOISTURE WITH MOSTLY LIGHT PRECIPITATION ACROSS
PARTS OF THE NORTH AND NORTHEAST COASTAL SECTIONS OF PUERTO RICO
AND MOSTLY THE NORTHERN VIRGIN ISLANDS DURING THE EARLY MORNING
HOURS. THIS WILL BE FOLLOWED BY GRADUAL DIMINISHING OF CLOUDS AND
AND PRECIPITATION THE REST MORNING AND EARLY AFTERNOON. THEREAFTER
MOSTLY FAIR WEATHER SKIES WILL PREVAIL. HOWEVER...THE LIMITED
MOISTURE AVAILABLE MAY BE AIDED BY SOME OROGRAPHIC FORCING TO
GIVE WAY TO ISOLATED AFTERNOON CONVECTION IN SOME SPOTS ACROSS
PARTS OF THE INTERIOR SECTIONS OF PUERTO RICO. THE REMAINDER OF
THE FORECAST AREA IS EXPECTED TO EXPERIENCE RELATIVELY DRY AND
BREEZY CONDITIONS OVER THE NEXT FEW DAYS AT LEAST UNTIL TUESDAY.
THEREAFTER...LOCAL WIND WILL GRADUALLY DIMINISH AS THE SURFACE
HIGH PRESSURE NORTH OF THE AREA RELAXES...AND A LOW PRESSURE SYSTEM
ACROSS THE CENTRAL ATLANTIC RETROGRADES WEST NORTHWEST AS PREVIOUSLY
MENTIONED. A SLIGHT INCREASE IN TROPICAL MOISTURE IS EXPECTED ONCE
AGAIN BY THE END OF THE WEEK.

Good morning
The high winds that have been plaguing us since the cold front passed through have died down this morning.
As you can see from the article linked below, the winds caused our Sea rescue to be quite busy rescuing some boats that broke loose from their anchors.

Good afternoon. Good weather for the next three days and then increasing showers with some thunderstorms during next weekend.

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SAN JUAN PR
249 PM AST TUE APR 17 2012

.SYNOPSIS...SURFACE HIGH PRESSURE TO THE NORTHWEST OF THE LOCAL
AREA AND A SURFACE LOW PRESSURE ACROSS THE CENTRAL ATLANTIC IS
CAUSING A TIGHT PRESSURE GRADIENT THAT WILL MAINTAIN MODERATE TO
LOCALLY FRESH WINDS ACROSS THE LOCAL AREA UNTIL WEDNESDAY. THIS
WILL ALSO MAINTAIN A STABLE AIR MASS ACROSS THE AREA...KEEPING THE
WEATHER FAIRLY DRY UNTIL FRIDAY.

&&

.DISCUSSION...WE ARE STILL UNDER THE SAME DRY AND STABLE AIR MASS
THAT IS KEEPING US UNDER FAIR WEATHER PATTERN WITH A MODERATE
BREEZE. 12Z SOUNDING INDICATED ONLY 0.78 INCHES OF PRECIPITABLE
WATER AND FORECAST SOUNDINGS INDICATE THAT THE PRECIPITABLE WATER
OVER THE AREA SHOULD REMAIN AT AROUND 1 INCH OR LOWER UNTIL
FRIDAY. THIS IS DUE BECAUSE THE LOW PRESSURE OVER THE CENTRAL
ATLANTIC IS FORECAST TO WEAKEN AND THEN MOVE NORTHEAST...AT THE SAME
TIME THAT A SURFACE LOW DEVELOPS OVER THE EASTERN UNITED
STATES...BRINGING IN MOISTURE FROM THE SOUTH TO OUR LOCAL AREA.
THERE IS ALSO AN UPPER TROUGH THAT THE GFS MODEL DEVELOPS TO THE
NORTH OF THE AREA FOR THE WEEKEND...WHICH WILL CREATE A BETTER
ENVIRONMENT FOR THE DEVELOPMENT OF SHOWERS AND ISOLATED
THUNDERSTORMS.


&&

.AVIATION...PREVAILING VFR CONDITIONS WILL CONTINUE ACROSS THE LOCAL
ISLANDS AND AT ALL TAF SITES THROUGH THE NEXT 24 HOURS. HOWEVER...
VERY BRIEF MVFR CONDITIONS AND LOCAL MOUNTAIN OBSCURATIONS ARE

SLIGHTLY AFTER THAT.

THE SURFACE HIGH ACROSS THE THE WESTERN ATLANTIC IS EXPECTED TO
WEAKENS WHILE MOVES TO THE NORTHEAST. A LOW PRESSURE AREA WILL THEN
DEVELOP ACROSS THE EASTERN UNITED STATES SEABOARD. AS THIS HAPPENS
THE LOW LEVEL WINDS ACROSS THE REGION WILL SHIFT FROM THE EAST BY
THE UPCOMING WEEKEND AND FROM THE SOUTHEAST BY MONDAY NEXT WEEK.
THIS WILL BRING DEEP TROPICAL MOISTURE ACROSS THE LOCAL ISLANDS FROM
THE SOUTHEAST...INDUCING AN INCREASE IN CLOUDINESS...SHOWERS

METEO. Guadeloupe in yellow for heavy rains and thunderstorms

franceantilles.fr18.04.2012
http://www.microsofttranslator.com/bv.a ... 166762.php

Low time, accompanied locally by storm-storm episodes, will persist until at least tomorrow.

The presence on our region of a cold front and the ascent to the South of a moist air create a sullen and storm-storm episodes time locally. This type of often cloudy weather will persist until at least tomorrow. The rains are not continuous and widespread, but they can be stormy and so intense. Where risk of spillovers of gullies, local floods and lightning strikes.

AND CONTINUING THROUGH THE END OF THE WEEK.

&&

.DISCUSSION...SHOWERS HAVE JUST BEGUN TO FORM IN PARTLY CLOUDY
SKIES THIS AFTERNOON. INTENSE HEATING HAS GENERATED REPORTS OF FIRES IN
MAYAGUEZ AND WHIRLWINDS IN GUAYAMA. FIRES MAY HAVE ALSO BEEN SEEN
IN SALINAS IN SATELLITE IMAGERY. WITH MODEST EAST NORTHEAST
FLOW...SEA BREEZES HAVE BEEN PREDOMINANT OVER MOST COASTAL AREAS.

DRY AIR WILL CONTINUE OVER THE AREA UNTIL FRIDAY WHEN MOISTURE
RETURNS FROM THE SOUTHEAST. FROM FRIDAY TO TUESDAY FLOW CONTINUES
TO HAVE A SOUTHERLY COMPONENT THAT BRINGS INCREASING MOISTURE AND
SHOWERS IN FROM THE SOUTHEAST. AS MOISTURE FILLS IN AT MID AND
UPPER LEVELS SHOWERS WILL BECOME MORE WIDESPREAD AND
STRONGER...ESPECIALLY IN THE WEST AND NORTHWEST PARTS OF PUERTO
RICO DURING THE WEEK NEXT WEEK. AT PRESENT IT LOOKS LIKE MOST OF NEXT
WEEK WILL BE SHOWERY. WITH BETTER DIURNAL HEATING...EXPECT A
GREATER FREQUENCY OF THUNDERSTORMS AS WELL. IT IS TOO EARLY TO SAY
MUCH ABOUT POSSIBLE FLOODING...BUT EXPECT THE BEST MOISTURE TO BE
OVER THE DOMINICAN REPUBLIC RATHER THAN PUERTO RICO OR THE U.S.
VIRGIN ISLANDS.

&&

.AVIATION...VERY BRIEF MVFR CONDITIONS WILL REMAIN POSSIBLE THROUGH
ABOUT 18/22Z OVER SOUTHWEST PUERTO RICO INCLUDING THE VICINITY OF
TJMZ AND TJPS DUE TO ISOLATED TO LOCALLY SCATTERED SHOWERS.ELSEWHERE...
VFR CONDITIONS EXPECTED NEXT 24 HOURS. LOW LEVEL WINDS FROM THE EAST
NORTHEAST AT 10 TO 15 KT.

&&

.MARINE...WINDS AND SEAS WILL DIMINISH...ALTHOUGH WINDS REMAIN
ABOVE 15 KNOTS IN THE SOUTHERN-MOST WATERS SOUTH OF PUERTO RICO
UNTIL FRIDAY. SEAS INCREASE SUNDAY INTO MONDAY BUT SMALL CRAFT
ADVISORIES ARE NOT EXPECTED DURING THE NEXT 7 DAYS.

Back to green alert here . Whereas, Meteo-France Guadeloupe continue to think that we have another high probability to deal with another episodes of strong showers and tstorms during the next 48H to 72h. Thus, a comeback to yellow alert is not impossible always given our Pro Mets... so let's follow what could happens during the next couple of days.
