.SYNOPSIS... MID UPPER LEVEL HIGH PRESSURE OVER THE WESTERN
CARIBBEAN WILL BUILD EAST OVER THE WEEKEND. COLD FRONT WILL
APPROACH THE LOCAL AREA WEDNESDAY.

&&

.DISCUSSION...RELATIVELY DRIER CONDITIONS ARE EXPECTED TO PREVAIL
DURING THE WEEKEND AS A HIGH PRESSURE SYSTEM ESTABLISH ACROSS THE
NORTHEAST CARIBBEAN. LATEST SATELITE IMAGES...SURFACE
OBSERVATIONS AND LATEST MIMIC TPW PRODUCT FROM CIMSS INDICATED
MOISTURE HAS DECREASE LAST 24 HOURS ACROSS THE AREA. ONLY SOME
PATCHES OF LOW LEVEL MOISTURE ASSOCIATED WITH THE REMNANT OF AN
OLD FRONTAL BOUNDARY WHICH AFFECTED THE LOCAL AREA THE PAST FEW
DAYS...WERE SEEN IN LATEST IR SATELLITE IMAGES. CONDITIONS ARE
EXPECTED TO GET DRIER AS WE APPROACH THE BEGINNING OF NEXT
WEEK...AS AN AREA OF DRY AIR MOVES ACROSS THE REGION. LATEST PROG
SOUNDINGS INDICATED PW VALUES WILL DROP AS LOW AS 1.2 INCHES
MONDAY AND TUESDAY. THIS WILL OCCUR AS SUBSIDENCE AIR MOVES OVER
THE AREA. AS THE HIGH PRESSURE SHIFT EAST...WINDS WILL SHIFT MORE
TOWARD THE SOUTHEAST...WHICH WILL INDUCE WARMER THAN NORMAL
MAXIMUM TEMPERATURES MAINLY ALONG THE NORTH COAST OF PUERTO RICO
DURING THE NEXT DAY OR TWO. BY WEDNESDAY...A COLD FRONT IS
EXPECTED TO APPROACH THE LOCAL AREA FROM THE
NORTHWEST...INCREASING ONCE AGAIN THE CHANCES FOR PRECIPITATION
ACROSS THE LOCAL REGION. IF THE MODELS ARE RIGHT...LOOKS LIKE THE
WETTEST DAY WILL BE WEDNESDAY..WITH THE COLD FRONT APPROACHING THE
LOCAL AREA FROM THE NORTHWEST...AND MOISTURE AT LOW LEVEL WILL COME
FROM THE SOUTHEAST. HOWEVER...AT THIS TIME...NO WIDESPREAD
RAINFALL IS EXPECTED. IN THE LONG TERM...NO SIGNIFICANT WEATHER
EVENTS ARE FORECAST TO AFFECT THE NORTHEAST CARIBBEAN AT THIS
TIME.

Today has been the warmest morning in San Salvador this month and one of the warmest (if not THE warmest this year). The lowest temperature this morning in San Salvador marked 20.9 °C/69.6 °F and to think that on Tuesday we had less than 16°C/60 °F. Other cities in El Salvador and Central America experienced their warmest night/dawn too, some examples:

Santa Ana, El Salvador 20.6 °C/69.1 °F
San Miguel, El Salvador 24 °C/75.2 °F
Guatemala, Guatemala 17 °C/62.6 °F
Tegucigalpa, Honduras 20 °C/68 °F

.SYNOPSIS...MID UPPER LEVEL HIGH PRESSURE WILL DOMINATE INTO EARLY
NEXT WEEK. COLD FRONT EXPECTED TO MOVE INTO THE AREA TUESDAY NIGHT
AND STALL WEDNESDAY BEFORE RETREATING TO THE NORTH THURSDAY. MID-
UPPER LEVEL RIDGE EXPECTED TO BUILD AGAIN FOR NEXT WEEKEND.

&&

.DISCUSSION...NO MUCH TO TALK ABOUT THIS MORNING IN TERMS OF
WEATHER ACROSS THE LOCAL AREA. CLEAR SKIES HAVE PREVAILED
OVERNIGHT...WITH NO SHOWER ACTIVITY OBSERVED OVER PUERTO RICO.
SOME VERY LIGHT SHOWERS WERE DETECTED BY THE DOPPLER WEATHER RADAR
OVER THE CARIBBEAN WATERS. FEW OF THESE SHOWERS MOVED OVER SAINT
THOMAS BETWEEN 0400-0430Z...BUT VERY LITTLE RAINFALL WAS DETECTED.
THIS DRY WEATHER PATTERN IS IN RESPONSE DUE TO A HIGH PRESSURE SYSTEM
WHICH IS IN TOTAL CONTROL ON OUR WEATHER LOCALLY...AND NO CHANGES
ARE EXPECTED TO OCCUR IN THE SHORT TERM...AS THIS MID TO UPPER
LEVEL HIGH ESTABLISH OVER THE AREA. LOCAL WRF MODEL INDICATED VERY
DRY CONDITIONS WILL PREVAIL TODAY...WITH THE MODEL ONLY INDICATING
THE POSSIBILITY OF SOME SHOWERS ACROSS THE NORTHWEST SECTION OF
PUERTO RICO. TAKING IN CONSIDERATION LAST DAY WE DIDN'T RECEIVED
RAIN AT ALL...NO SIGNIFICANT RAINFALL IS EXPECTED TODAY
ALSO...SINCE DRIER CONDITIONS ARE EXPECTED. LATEST 00Z TJSJ SOUNDING
SHOWED PW VALUES WERE 1.46 IN. NAM12 AND GFS COMPUTER MODELS
AGREED THAT THESE VALUES WILL DROP EVEN MORE TONIGHT AND
MONDAY...AS AN AREA OF DRIER AIR MOVES OVER THE NORTHEAST
CARIBBEAN. MAIN MOISTURE WILL BE CONFINE AT LOW LEVEL..BUT MID TO
UPPER LEVEL OF THE ATMOSPHERE WILL BE VERY DRY.

FOR TUESDAY NIGHT AND WEDNESDAY...THE HIGH PRESSURE WILL SHIFT
EAST...AND THIS WILL ALLOW A COLD FRONT TO APPROACH THE LOCAL AREA
FROM THE NORTHWEST. ALSO...COMPUTER MODELS SUGGEST THAT AN AREA OF
MOISTURE WILL APPROACH THE LOCAL AREA FROM THE SOUTHEAST. ALTHOUGH
NO SIGNIFICANT RAINFALL IS EXPECTED WITH THE COMBINATION OF THESE
FEATURES...DEFINITELY WE WILL SEE A SIGNIFICANT INCREASE IN CLOUD
COVERAGE ACROSS THE REGION...STARTING TUESDAY NIGHT...AND
CONTINUING UNTIL AT LEAST THURSDAY...WHEN THE COLD FRONT OR ITS
REMNANTS MOVE NORTH...AND AN UPPER LEVEL RIDGE BUILDS AGAIN. AFTER
THURSDAY...CONDITIONS LOOKS VERY DRY FOR NEXT WEEKEND. HOWEVER...
AT THIS TIME IS TOO EARLY TO KNOW IF THE COMPUTER MODELS ARE RIGHT
ON THIS.

WINDS ARE EXPECTED TO CONTINUE MAINLY FROM THE SOUTHEAST AT LEAST
UNTIL THE COLD FRONT APPROACH THE LOCAL AREA. THEREFORE...WARMER
THAN NORMAL MAXIMUM TEMPERATURES ARE LIKELY TO OCCUR MAINLY ALONG
THE NORTHERN COAST OF PUERTO RICO AT LEAST THROUGH TUESDAY.

&&

.AVIATION...SHOWERS OVER LOCAL WATERS WILL DISSIPATE FOR THE MOST
PART DURING THE DAY AND BRIEF MVFR CONDITIONS IN TIST AND TISX WILL
GIVE WAY TO VFR AT ALL LOCATIONS BY 14/14Z. PERIODS OF MVFR WILL BE
POSSIBLE IN THE MID AND LATE AFTERNOON IN NORTHWEST PUERTO RICO

It continues to be very dry in Barbados. There have been reports of drizzles, but so far, I haven't heard, seen or felt any rain in a while! Farmers are complaining that they have difficulty growing some produce, and the birds might be looking for more food too!

[tropicana]

UPDATE: Sun March 14, 2010

DAY # 39

Feb 4 -March 14 **and counting ... no measurable rainfall across trinidad and tobago
##the existing record appears to be 41 days March 28- May 7 1986 (re-calculated) for western Trinidad.
We are now within 2 days of this record.
NOTE: This record is for western Trinidad.
While this period was a dry period islandwide as well, Piarco Airport, located in Central Trinidad did recieve 8mm of rain on Apr 18, 1986, while western Trinidad remained dry.
The international Airport has never gone more than 30 days consecutively without rainfall, prior to 2010.


Sunny, hazy skies continued to be the order of things, with temperatures reaching a high of 34.8C 95F at Piarco International Airport on Sunday afternoon.
Since Feb 23, the temperature has reached or exceeded 33.7C 93F every day ( a string of 20 days consecutively) and most of those days, reached 94F and 95F..unprecedented in all the available data.

It has been a warm day in El Salvador too, the cold front that extends from North America was not strong enoguh to affect the country and it only had effects in northern Guatemala and Honduras. The temperatures this morning were the warmest so far this year, some low temperatures this morning:

Acajutla (west coast): 25.1 °C/77.2 °F
San Salvador: 22.1 °C/71.8 °F
San Miguel: 25.4 °C/77.7 °F

Those minimum temperatures are more likely too occur in April wich is the month that has the warmest nights/dawns.

The maximum temperatures yesterday were one of the highest this year as well (something normal for March), some examples:

Santa Ana 33.4 °C/92.1 °F
San Salvador 32°C/89.6 °F
San Miguel 37.5 °C/99.5 °F

[cycloneye]

Good morning to all.

A mostly dry week ahead as the next front will not be a wet one.

.SYNOPSIS...AT UPPER LEVELS...HIGH PRESSURE REMAINS OVER NORTHERN
SOUTH AMERICA. FLOW IS WESTERLY BUT TURNS SOUTHWEST ONLY AFTER A
TROUGH DIGS INTO THE GULF OF MEXICO LATE IN THE 10 DAY PERIOD.

AT MID LEVELS...LOW PRESSURE OVER THE ATLANTIC OPPOSITE THE
NORTHEASTERN UNITED STATES WILL MOVE INTO THE CENTRAL ATLANTIC BY
WEDNESDAY AND OPEN UP INTO A TROUGH. LOW PRESSURE IS SET TO CROSS
FLORIDA ON THURSDAY. HIGH PRESSURE WILL STRENGTHEN OVER THE
TROPICAL ATLANTIC THROUGH SATURDAY. MID LEVELS WILL REMAIN MOSTLY
DRY.

AT LOWER LEVELS...A COLD FRONT WILL CONTINUE TO SAG TOWARD PUERTO
RICO AND THE U.S. VIRGIN ISLANDS FROM A POSITION OVER EASTERN
CUBA. THE FRONT SHOULD MOVE OVER THE LOCAL AREA ON WEDNESDAY AND
THEN BACK OUT ON THURSDAY...LEAVING THE LOCAL AREA DRY FOR MUCH OF
THE REST OF THE WEEK.

&&

.DISCUSSION...A FEW LIGHT SHOWERS HAVE BEEN SEEN OVER THE LOCAL
WATERS AND SOME OF THE SHOWERS OVER THE CARIBBEAN MOVED ONSHORE IN
THE SOUTHEAST PART OF PUERTO RICO...AMOUNTS WERE LIGHT IF MEASURABLE. THE
NAM AND THE GFS BRING MOISTURE OVER THE AREA TUESDAY AFTERNOON
THROUGH WEDNESDAY AND THE NAM ALSO FORMS A BAND OF CLOUDS AND
SHOWERS TO THE SOUTHEAST OF PUERTO RICO IN THE WATERS BETWEEN
SAINT CROIX AND PUERTO RICO. MOISTURE LINGERS ON THURSDAY BUT
DRIER WEATHER IS EXPECTED FRIDAY THROUGH SUNDAY. THE NEXT BAND OF
MOISTURE ARRIVES SUNDAY NIGHT.

MODELS ARE OPTIMISTIC ABOUT THE RAIN...ESPECIALLY THE GFS...WHICH
DID WELL DURING THE LAST FRONTAL EVENT...BUT NEITHER MODEL IS AS
STRONG ON SHOWERS AS LAST TIME...THEREFORE HAVE NOT BOOSTED POPS
FOR WEDNESDAY AND THURSDAY AT THIS TIME. ONSHORE FLOW SHOULD BEGIN
ON WEDNESDAY AND ENHANCE THE RAINFALL FOR THE NORTH COAST
AGAIN...BUT FRONT LOOKS LIKE IT MAY BE FARTHER EAST OF THE AREA
WHEN IT ARRIVES...LEAVING THE BOUNDARY PASSAGE WEAKER. DRIER
WEATHER STILL FORECAST FOR THE WEEKEND...BUT MAY END ABRUPTLY ON
SUNDAY WHEN A PATCH OF MOISTURE FROM A FRONTAL ZONE NORTHEAST OF
THE AREA RETURNS.

TODAY WILL BE WARMER THAN USUAL AGAIN ON THE NORTH COAST...BUT
WITH THE RECORD AT 93 DEGREES...IT SEEMS UNLIKELY THAT SAN JUAN WILL
BREAK THROUGH THAT TEMPERATURE...NEVERTHELESS EXPECT LOWER 90S IN
THE SAN JUAN METRO AREA AGAIN THIS AFTERNOON WITH SOUTHEAST WINDS
THAT WILL PERHAPS GIVE WAY TO A SEA BREEZE LATE IN THE DAY.

&&

.AVIATION...
EXPECT PREVAILING VFR CONDITIONS TO CONTINUE ACROSS THE
LOCAL ISLANDS AND AT ALL LOCAL TAF SITES FOR AT LEAST THE NEXT 24
HOURS. WINDS WILL CONTINUE MAINLY SOUTHEAST AT 10 TO 15
KNOTS...EXCEPT FOR SEA BREEZE VARIATIONS AT COASTAL AREAS.

&&

.MARINE...SEAS WILL REMAIN RELATIVELY TRANQUIL FOR NOW...BUT WHEN
NORTHWEST WINDS AROUND THE LOW OFF THE EASTERN SEABOARD REACH
WATER IT WILL SEND SWELL TOWARD THE AREA AND RAISE SEAS TO SMALL
CRAFT ADVISORY CRITERIA BY WEDNESDAY. SMALL CRAFT WILL HAVE TO
EXERCISE CAUTION IN THE ATLANTIC WATERS AND PASSAGES FOR A
CONSIDERABLE AMOUNT OF TIME AFTER THE SWELL DIE DOWN.

GO SAN JUAN GO! we want another record! haha

just kidding cyclone! well, no im not!


Some slight relief for some of the Windward Islands, Grantley Adams B'dos has seen 5mm of rain overnight, 1.3mm at Rockley, Christchurch on the south coast.
Crown Point, Tobago got 0.3mm not a lot, but at least some.
Poor Trinidad, just a trace of rain reported at the airport there on this, the 40th day of the dry spell. Point Salines, Grenada also got just a trace.

waouw Trinidad in route for another awesome record let's hope hat things will change quickly during the next couple of days...

[abajan]

Well, we’re finally getting lots of much needed rain here!
It began last night with a short but heavy shower and now today has been quite rainy so far with frequent showers - some of them heavy. Hopefully, it continues like this for the rest of the day and into the night. (For obvious reasons, there’s very little chance of flooding.)

308 PM AST MON MAR 15 2010

.SYNOPSIS...GENERALLY FAIR WEATHER AND UNSEASONABLY WARM WEATHER
IS EXPECTED ACROSS THE LOCAL ISLANDS FOR THE NEXT WEEK. THE BEST
CHANCE FOR ANY SHOWERS WILL BE LATE TOMORROW AFTERNOON THROUGH
WEDNESDAY AFTERNOON...AS THE COMBINATION OF AN OLD FRONTAL BOUNDARY
TO OUR NORTHWEST AND MOISTURE FROM THE SOUTHEAST WILL BRING SOME
CLOUDS...AND A FEW SHOWERS...ACROSS THE LOCAL ISLANDS.

&&

.DISCUSSION...ANOTHER WARM AND DRY DAY ACROSS NORTHERN PUERTO RICO
TODAY. A VERY LIGHT PRESSURE GRADIENT AHEAD OF THE FRONT ACROSS
HISPANIOLA ALLOWED THE DEVELOPMENT OF A SEA BREEZE THROUGH THE
MORNING HOURS...BUT BY EARLY AFTERNOON...THE SYNOPTIC SCALE
SOUTHEASTERLY WINDS PREVAILED AND TEMPERATURES SPIKED ACROSS
NORTHERN PUERTO RICO.

THE WEAK FRONTAL BOUNDARY TO OUR NORTHWEST IS EXPECTED TO BRING A
FEW CLOUDS AS IT APPROACHES LATE TOMORROW AFTERNOON...BUT BETTER
MOISTURE AND CLOUD COVER IS EXPECTED WITH BAND OF MOISTURE
CURRENTLY ADVECTING NORTHWESTWARD ACROSS GUADELOUPE. THIS BAND OF
MOISTURE WILL LIKELY BRING VARIABLY TO MOSTLY CLOUDY SKIES AND
SCATTERED SHOWERS ACROSS THE LOCAL ISLANDS LATE TOMORROW THROUGH
WEDNESDAY. WHILE OVERALL NOT A LOT OF PRECIPITATION IS
EXPECTED...IT WILL BE A CHANGE FROM CURRENT SUNNY CONDITIONS.
HOWEVER...THIS BREAK IS EXPECTED TO BE BRIEF AS HIGH
PRESSURE...LIMITED MOISTURE...AND A GENERAL SOUTHEASTERLY WIND
FLOW WILL THEN PREVAIL FROM THURSDAY THROUGH THE UPCOMING WEEKEND...
WITH LITTLE TO NO SHOWER ACTIVITY EXPECTED THOSE DAYS.

&&

.AVIATION...VFR CONDITIONS NEXT 18 HRS. SHIFTING WINDS EXPECTED
MIDDAY TOMORROW ASSOCIATED WITH A SHEARLINE. ANTICIPATING SCT

Regional Weather Round-up Mon Mar 15 2010


Piarco Airport, Trinidad 34.8C 95F TRACE
Crown Point, Tobago 31.5C 2mm
Point Salines, Grenada 30.6C 87F
Grantley Adams, Barbados 30.6C 87F 10mm ( 31.0mm at Rockley, Christchurch)
Arnos Vale , St Vincent 30.6C 87F 21.2mm
Hewannora, St Lucia 31.6C 89F 0.4mm
Vigie, St Lucia 31.2C 88F 5.0mm
Le Lamentin, Martinique 32.7C 91F 0.2mm
Le Raizet, Guadeloupe 32.4C 90F trace
Melville Hall, Dominica 30.0C 86F 1.1mm
Canefield Airport, Dominica 32.2C 90F trace
San Juan, Puerto Rico 33.3C 92F

Unstable conditions produced the first widespread outbreak of showers in over 6 weeks across the Southern portion of the island chain. Some areas got quite a lot of rainfall, while other spots remained unscathed. Portions of Barbados were swamped with very heavy downpours, including the south coast where Rockley got over 1 1/4 inches of welcome rain and also reliable reports of rain from the Northern part of the island.
Arnos Vale also saw close to 1 inch of rain.
While Piarco Airport, Central Trinidad did not receive appreciable rainfall from this event, reliable reports of briefly heavy showers over central west areas of the island, and along the hills of the Northern Range, but the North-west suburb of Maraval saw just 0.5mm. Still, that was enough to break a consecutive dry spell in this area since Feb 4, a 39 day spell.

Piarco Airport continued dry trend, with just a trace of rain, now in its 40th day of no appreciable rainfall.
The heat was not tempered either, with top temperatures to 34.8C 95F again, the 21st consecutive day at or over 33.7C 93F.
