AREA FORECAST DISCUSSION

302 PM AST SUN APR 11 2010
.SYNOPSIS...
SURFACE HIGH PRESSURE ACROSS THE NORTH CENTRAL ATLANTIC...AND AN
EVEN STRONGER AREA OF HIGH PRESSURE WHICH WILL BUILD AND SPREAD
EAST ACROSS THE WEST ATLANTIC... WILL HELP MAINTAIN A FAIRLY TIGHT
PRESSURE GRADIENT ACROSS THE REGION...AND THUS CREATE A MODERATE
TO STRONG TRADE WIND FLOW ACROSS THE NORTHEAST CARIBBEAN FOR THE
NEXT SEVERAL DAYS. WEAK MID TO UPPER LEVEL RIDGE ACROSS THE REGION
WILL CONTINUE TO ERODE OVER THE NEXT SEVERAL DAYS AS BROAD TROUGH
BECOMES AMPLIFIED AND SPREADS EASTWARD ACROSS THE WEST AND
SOUTHWEST ATLANTIC. THIS WILL RESULT IN SEVERAL SHORT WAVE
PERTURBATIONS AND ASSOCIATED AREAS OF PVA TO BE DRIVEN BY THE
SUBTROPICAL JET STREAM AROUND THE BASE OF TROUGH AND ACROSS THE
REGION THOUGH MUCH OF THE UPCOMING WEEK...AS A SURGE OF DEEP
TROPICAL MOISTURE WILL MOVE ACROSS THE REGION ACCOMPANYING AN
INDUCED SURFACE TROUGH.
&&
.DISCUSSION...
STRONG EASTERLY TRADES WILL CONTINUE TO PUMP INTERVALS OF LOW
LEVEL MOISTURE ACROSS THE REGION THE REST OF THE DAY THROUGH
MONDAY. BASED ON LATEST LOCAL UPPER AIR DATA AND MIMIC PRODUCT
ANALYSIS...PWAT VALUES CONTINUED TO SHOW AN INCREASING TREND WITH
VALUES NOW BETWEEN 1.45-1.60 INCHES ACROSS THE LOCAL AREA. GFS
MODEL GUIDANCE WHICH INITIALIZED WELL TODAY WAS ALSO PERSISTENT IN
INCREASING VALUES ACROSS THE REGION TO AS MUCH AS 2.0 INCHES BY
THE END OF THE UPCOMING WEEK. THEREFORE...EXPECT THE COMBINATION
OF AVAILABLE MOISTURE AND LOCAL AND DIURNAL EFFECTS TO ENHANCE
SHOWERS DEVELOPMENT ACROSS PARTS OF THE CENTRAL INTERIOR AND WEST
SECTIONS PUERTO RICO...AS WELL AS OVER PARTS OF THE VIRGIN ISLANDS
DURING THE REST OF THE AFTERNOON HOURS AND EARLY EVENING HOURS.
EXPECT THE ACTIVITY TO DRIFT TOWARDS THE WEST SOUTHWEST DURING THE
AFTERNOON HOURS THEN GRADUALLY DISSIPATE AFTER SUNSET. SOME OF THE
SHOWERS WILL PRODUCE PERIODS OF LOCALLY HEAVY RAINFALL WILL LEAD
TO SOME MINOR URBAN AND SMALL STREAM FLOODING.
FOR THE UPCOMING WEEK...STILL LOOKS LIKE FAIRLY ACTIVE WEATHER
WEEK AS DEEP TROPICAL MOISTURE AND MID TO UPPER LEVEL INSTABILITY
WILL BE ON THE INCREASE ...RESULTING IN ENHANCED DAILY SHOWER AND
THUNDERSTORM DEVELOPMENT. THE STRONGEST AFTERNOON CONVECTION WILL BE
FOCUSED MAINLY ACROSS THE INTERIOR AND WESTERN SECTIONS OF PUERTO
RICO... WITH PERIODS OF ISOLATED TO SCATTERED SHOWERS EXPECTED
ACROSS THE VIRGIN ISLANDS AND EAST SECTIONS OF PUERTO RICO DURING
THE MORNING HOURS.

Re: Caribbean - CA Weather=Rain falling in parts of E.Carib
TRINIDAD UPDATE
Sun Apr 11, 2010
DAY # 48 of Heatwave 35.5C 96F today
Feb 23-Apr 11 *and counting... daily highs at or over 33.7C 93F, a very rare event in the Eastern Caribbean for such an extended period
No relief in Trinidad as Piarco temperatures shot up to 35.5C 96F on Sunday afternoon. It is now the 48th consecutive day of highs at or over 33.7C 93F.
The trough in the Eastern Caribbean brought substantial rainfall to islands from Barbados north to Guadeloupe this weekend.
The rain continued today on Guadeloupe, providing that island with a further 14mm of rain in the 6 hours to 2pm. Barbados and St Lucia saw very heavy rainfall overnight.
Currently, there is an area of showers in the waters between Trinidad and Grenada and Barbados but not currently affecting any land mass. April rainfall at Piarco remains at a paltry 0.4mm, while over in Barbados, Grantley Adams has now seen near 55mm for the month.
The sun continues to apparently move northward , and will be directly over the latitude of Trinidad-Tobago during the last week of April, on it's apparent journey northward toward the Tropic of Cancer... and the intense heat is likely to continue.

Re: Caribbean - Centralamerica Weather Thread
Barbados now is green again after a fair amount of rain over the last several days. It's truly a beautiful sight and I hope Trinidad & Tobago will soon be able to report similar conditions.cycloneye wrote:I am glad to see that some of the islands are recieving rain.

Looks like that things are turning quickly 
...as Martinica has issued this morning an YELLOW ALERT for a risk of strong showers. 
http://www.meteo.gp/donnees/bulletin/vi ... ilance.php
Martinica also reported good amounts of water in some areas during the last 24h: Sainte-Marie-Pérou: 68 millimeters, Fort de France:55 millimeters.
Seems that this moist and unstable mass should continue to bring good showers and a small risk of tstorms in Guadeloupe tommorow and Wednesday given our Pro mets of Meteo-France Guadeloupe.
Thus an yellow alert is not impossible but pretty possible tommorow always given Meteo-France Guadeloupe. So, very good news for all the E carib islands, seems that the drought could be partially erase with these juicy amounts of water:wink:

YELLOW ALERT have been issued for Guadeloupe at 11 AM due to a risk of strong showers and tstorms... For information here are the:
LATEST MEASUREMENTS from yesterday 8AM to Monday 8AM (in millimeters):
Petit-Bourg (Duclos): 70,5 (not so far from my locality)
Marie-Galante: 64,5
Pointe-A-Pitre: 45,4
Basse-Terre: 31,2
La Désirade: 19,5
Saint-Barthélémy: 14,4
Sainte-Anne: 7,5
Le Moule: 6,4
Moreover, Meteo-France reported today more than 50 millimeters (at Gosier/Sainte-Anne) and 45 millimeters at Baie-Mahault/Petit-Bourg in only 2 hours!!! We should stay in yellow alert at least Tuesday night. Anyway i will try to keep you informed as usual and as possible if the weather conditions allow it.
You understand my friends that we're enjoying ...finally this wet episode, that's a good bath for the trees the plants etc. But in spite of this generous situation for Guadeloupe and some of the islands of the East Carib islands, my thoughts are for Trinidad! Let's hope that some rain will come soon and it's an euphemisma in this beautiful island suffering from an unrealistic and catastrophic drought 
!!!
Regards

Re: Caribbean - CA Weather=Rain falling in parts of E.Carib
Afternoon discussion by NWS San Juan
As forecast,a wet week ahead for the Eastern Caribbean.Hopefully,Trinidad & Tobago gets some of this weather to aliviate the drought conditions there.
AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SAN JUAN PR
344 PM AST MON APR 12 2010
.SYNOPSIS...AT MID AND UPPER LEVELS...WINDS OVER THE AREA ARE WEST
SOUTHWESTERLY DUE TO HIGH PRESSURE SOUTHEAST OF THE WINDWARD
ISLANDS AND A PASSING TROUGH TO THE NORTH. THERE IS A STRONG JET
BETWEEN 22 AND 25 NORTH AT UPPER LEVELS THAT WILL HAVE SOME
INFLUENCE ON THE WEATHER TUESDAY THROUGH FRIDAY.
AT LOWER LEVELS...MOISTURE IN THE LOCAL AREA WILL CONTINUE TO
PRODUCE SHOWERS THAT WILL EVENTUALLY ALLOW A LOW TO FORM OVER OR
JUST NORTH OF THE U.S. VIRGIN ISLANDS. THIS WILL LOWER LOCAL WIND
SPEEDS...PUT PUERTO RICO IN NORTHERLY FLOW WEDNESDAY THROUGH FRIDAY AND
KEEP CONVERGENCE AND MOISTURE AROUND. MODELS SHOW UNUSUAL WIND
FLOW AND UNSETTLED WEATHER FOR MUCH OF NEXT WEEK AS WELL
&&
.DISCUSSION...A PERSISTENT AREA OF MOISTURE AROUND THE LOCAL AREA
IS CREATING WEAK LOW PRESSURE SYSTEMS THAT WILL PRODUCE UNUSUAL
WIND FLOWS AROUND THE AREA AND MAINTAIN CONVERGENCE AND SHOWERS
THROUGHOUT THE NEXT 7 TO 10 DAYS. CONFIDENCE IN THE MODELS AS TO
SPECIFIC DETAILS IS LOW...WINDS MAY SHIFT TO ANY DIRECTION
DEPENDING ON THE EXACT LOCATIONS THESE LOWS FORM AND THEREFORE
RAIN PATTERNS OVER THE MAIN ISLAND OF PUERTO RICO WILL BE HIGHLY
UNCERTAIN. EASTERLY FLOW TODAY WILL TURN SOUTHEAST LATER TONIGHT
AT 850 MB AND AN AREA OF WEAKNESS LOOKS LIKE IT WILL DEVELOP NORTH
OR NORTHEAST OF PUERTO RICO AND THE LEEWARD ISLANDS...HEAVIER RAIN
WILL OCCUR THERE. NORTHERLY FLOW FROM A HIGH TO OUR
NORTHWEST WILL SHIFT THIS AREA EAST...BUT WILL LIKELY LEAVE THE
ISLANDS IN A TRAILING TAIL OF CONVERGENCE. AFTER A BRIEFLY DRIER
PERIOD SATURDAY...THE GFS FORMS ANOTHER LOW OVER THE BAHAMAS
PULLING SOUTH WINDS OVER THE LOCAL AREA WITH ANOTHER BAND OF
MOISTURE. THIS FLOW TURNS SOUTHWEST AND CREATES A VERY UNUSUAL
WIND FLOW FOR THE SEASON. FOR THIS REASON POPS CLOSE TO 50 PERCENT
HAVE BEEN SPREAD ACROSS MUCH OF THE AREA...AND THE WINDS FORECAST
IS LIKELY TO CHANGE SEVERAL TIMES OVER THE NEXT 3 TO 5 DAYS.
&&
.AVIATION...
MOSTLY VFR CONDS EXPECTED AT ALL TAF SITES WITH A PREVAILING
EASTERLY LLVL WIND FLOW AT 15 TO 20 KTS. MVFR CONDITIONS AND LOCAL
MOUNTAIN OBSCURATIONS ARE POSSIBLE MAINLY OVER THE
CENTRAL...WESTERN INTERIOR...AND WEST SECTIONS OF PUERTO RICO
THROUGH ABOUT 12/23Z.
ALSO VCSH OR PASSING SHRA EXPECTED ACROSS TNCM AND TKPK RESULTING IN
BRIEF PERIODS OF MVFR.
&&
.MARINE...SEAS HAVE MOSTLY BEEN RESPONDING TO LOCAL WINDS WITH
CHOP AND NEAR SMALL CRAFT CONDITIONS ALMOST EVERY WHERE EXCEPT IN
VERY PROTECTED AREAS IN THE WEST. THIS SHOULD DIMINISH BY
WEDNESDAY...BUT SEAS OF BETTER THAN 7 FEET RETURN TO THE NORTHERN
WATERS OVER THE WEEKEND.
As forecast,a wet week ahead for the Eastern Caribbean.Hopefully,Trinidad & Tobago gets some of this weather to aliviate the drought conditions there.

MOISTURE. THIS FLOW TURNS SOUTHWEST AND CREATES A VERY UNUSUAL
WIND FLOW FOR THE SEASON. FOR THIS REASON POPS CLOSE TO 50 PERCENT
HAVE BEEN SPREAD ACROSS MUCH OF THE AREA...AND THE WINDS FORECAST
IS LIKELY TO CHANGE SEVERAL TIMES OVER THE NEXT 3 TO 5 DAYS.
&&
.AVIATION...
MOSTLY VFR CONDS EXPECTED AT ALL TAF SITES WITH A PREVAILING
EASTERLY LLVL WIND FLOW AT 15 TO 20 KTS. MVFR CONDITIONS AND LOCAL
MOUNTAIN OBSCURATIONS ARE POSSIBLE MAINLY OVER THE
CENTRAL...WESTERN INTERIOR...AND WEST SECTIONS OF PUERTO RICO
THROUGH ABOUT 12/23Z.
ALSO VCSH OR PASSING SHRA EXPECTED ACROSS TNCM AND TKPK RESULTING IN
BRIEF PERIODS OF MVFR.
&&
.MARINE...SEAS HAVE MOSTLY BEEN RESPONDING TO LOCAL WINDS WITH
CHOP AND NEAR SMALL CRAFT CONDITIONS ALMOST EVERY WHERE EXCEPT IN
VERY PROTECTED AREAS IN THE WEST. THIS SHOULD DIMINISH BY
WEDNESDAY...BUT SEAS OF BETTER THAN 7 FEET RETURN TO THE NORTHERN
WATERS OVER THE WEEKEND.

Good morning.Rain falling here as I am typing this.There is plenty of moisture around as the radar picks up.
AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SAN JUAN PR
522 AM AST TUE APR 13 2010
.SYNOPSIS...AT MID AND UPPER LEVELS...WINDS OVER THE AREA ARE WEST
DUE TO HIGH PRESSURE SOUTHEAST OF THE WINDWARD ISLANDS AND A
PASSING TROUGH TO THE NORTH. THERE IS A STRONG JET BETWEEN 20 NORTH
AT UPPER LEVELS THAT WILL HAVE A DIRECT INFLUENCE ON THE WEATHER
THROUGH FRIDAY.
&&
.DISCUSSION...SCATTERD TO NUMEROUS SHOWERS AND ISOLATED THUNDERSTORMS
CONTINUED TO AFFECT THE LOCAL ATLANTIC OFF SHORE WATERS. ALSO SCATTERED
SHOWERS AFFECTED THE EASTERN PORTION OF PUERTO RICO...CULEBRA...VIEQUES
AND THE USVI. THESE SHOWERS HAVE REMAIN CONSISTENT THROUGH THE
OVERNIGHT HOURS...THEREFORE EXPECT MORE SHOWERS TO MOVE ON SHORE
AND AFFECT THE EASTERN AND SOUTHERN PORTIONS OF PUERTO RICO.
SIGNIFICANT CHANGES ON THE WEATHER PATTERN HAVE ALREADY STARTED AS
THE SUB TROPICAL JET IS NOW SITUATED NORTH OF OUR LOCAL FORECAST
AREA. THIS FEATURE WILL BRING MID LEVEL SHORT WAVES ACROSS THE
AREA THROUGH THE INCOMING WEEKEND. THESE SHORT WAVES WILL HELP IN
THE ENHANCEMENT OF AFTERNOON CONVECTION AND OVERNIGHT SHOWERS.
THE LOCATION OF THESE SHOWERS AND THUNDERSTORMS WILL BE TRICKY AS
MODELS SUGGEST THE DEVELOPMENT OF A LOW LEVEL LOW PRESSURE
SOMEWHERE IN OUR LOCAL REGION. WIND PATTERNS GENERATED BY THESE
LOW WILL DICTATE WHERE SHOWERS WILL BE CONCENTRATED. WE BASED
THESE FORECAST ON THE LATEST RUN OF THE GFS MODEL...WERE THE LOW
LEVEL LOW PRESSURE DEVELOPS NORTHEAST OF PUERTO RICO.
&&
.AVIATION...GENERALLY VFR CONDITIONS SHOULD PREVAIL ACROSS ALL TAF
SITES DURING THE MORNING HOURS. HOWEVER...BRIEF PERIODS OF MVFR
CONDITIONS ARE POSSIBLE ACROSS TJSJ...TISX...TIST...AND TJPS IN
PASSING SHOWERS. DURING THE AFTERNOON HOURS...MVFR CONDITIONS AND
LOCAL MOUNTAIN OBSCURATIONS ARE POSSIBLE ACROSS TJMZ...AND TJBQ
THROUGH 13/23Z.
&&
.MARINE...WINDS WILL CONTINUE TO SLIGHTLY DECREASE TODAY AND
THEREFORE SEAS SUBSIDING TO BELOW SCA CRITERIA ACROSS ALL LOCAL
WATERS. MARINER SHOULD MONITOR OUR FORECAST AS DANGEROUS MARINE
CONDITIONS COULD DEVELOP AFTER THURSDAY AS A HIGH PRESSURE BUILDS
ACROSS THE REGION INCREASING THE WINDS AND SEAS ACROSS THE ALL
LOCAL WATERS. THESE FRESH TO STRONG WINDS ARE EXPECTED TO GENERATE
CONFUSE SEAS THROUGH THE WEEKEND. THESE MARINE FORECAST IS BASED
IN THE DEVELOPMENT OF THE LOW LEVEL PRESSURE DEVELOPING NE OF THE
LOCAL REGION.
