TRINIDAD UPDATE: Fri Mar 26 2010

DAY # 32 of Heatwave
Feb 23-Mar 26 *and counting... daily highs at or over 33.7C 93F, an unprecedented hot spell unusual even for the tropics

Continued hot with temperatures at Piarco Airport in Central Trinidad reaching 34.1C 94F on Friday.
While there may be an odd spot shower on Saturday, the trend is certainly a drying one after a week of isolated showers.
This means more sunshine and with the very high late March sun angle, it means more heat

Since Feb 23, the temperature at Piarco Airport has reached or exceeded 33.7C 93F everyday, a period of 32 days, unprecedented even for the tropics.

.SYNOPSIS...MID LEVEL HIGH PRES WILL DOMINATE THE REGION WELL INTO
NEXT WEEK AND MAINTAIN A GENERALLY DRY PATTERN. RIDGE IS EXPECTED
TO BREAK DOWN NEXT WEEKEND AS A LONGWAVE TROUGH DEVELOPS ACROSS
THE WRN ATLC BRINGING A CDFNT CLOSE TO OUR AREA NEXT SAT.

AREA THROUGH THE MIDDLE OF NEXT WEEK AND MAINTAIN A DRY STABLE
ATMS WITH ONLY ISOLD AFTERNOON CONVECTION EXPECTED AT BEST OVR
WRN PR AND NOCTURNAL SHOWERS ACROSS THE WATERS. AM IGNORING THE NAM12
SOLUTION WHICH BRINGS SIG MOISTURE TO OUR AREA SUN. THE 00Z ECMWF HAS
TRENDED DRIER FOR SUN AND MORE IN LINE WITH THE MORE CONSISTENT
GFS SOLUTION WHICH SHOWS PWAT VALUES HOVERING AROUND AN INCH
THROUGH THE MIDDLE OF NEXT WEEK WHICH IS PRETTY DRY FOR THIS TIME
OF THE YEAR.

SIG CHANGES STILL APPEAR ON TRACK FOR NEXT WEEKEND AS OPERATIONAL
MODELS/ENSEMBLES SHOW RIDGE BREAKING DOWN WITH A DEEP CUTOFF LOW
DEVELOPING NORTH OF 30N AND ASSOCIATED TROF AXIS EXTENDING DOWN
INTO THE CNTRL CARIBBEAN. THIS WILL LIKELY BRING A SHEARLINE
THROUGH THE AREA FRI WITH ACTUAL CDFNT GETTING CLOSE TO PR NEXT
SAT. SO MUCH WETTER CONDITIONS APPEAR TO BE IN STORE FOR NEXT
SAT.

OR BETTER PROB OF 2-METER SEAS. A LONG FETCH DURATION EVENT LOOKS
TO SET UP ACROSS THE NCNTRL ATLC BETWEEN A SLOW MOVING LOW PRES

hi everyone
I've been traveling which is why I have not posted recently.
i am in Florida now, soon to come home.
I have stopped recently in Trinidad and St. Lucia and I cannot believe how dry and brown everything there is.
We saw many bush fires in the hills in Trinidad





and most of beautiful green St. Lucia is brown.
I have never seen the Caribbean so dry.

[cycloneye]

Wow Barbara,its really dry down there and I suppose in the whole Eastern Caribbean as our friends in the islands report how dry it has been apart from what our friend Justin (tropicana) reports.We can blame it to El Nino.Lets hope that the tropical waves start marching earlier than normal and dump the necessary rain to aliviate what the Eastern Caribbean is enduring.

[vbhoutex]

Maybe I need to change my predictions so the islands get some rain soon. I new there had been less rainfall than normal, but not as bad as it apparently is. Hard to think of the islands being in a drought situation.

45,000 people visit Hurricane Hunter in Puerto Rico

As part of the tour that they were doing thru the Caribbean and Centralamerica the final stop came to Roosvelt Roads airport in eastern Puerto Rico on Saturday.Is a new record for any tour of this kind to have this many people to visit the plane.There were other activities to the children as part of the stop here.The director and co director of the National Hurricane Center William Read and Ed Rappaport are part of this tour and answered questions from the public.

It seems like the weather is gradually changing back to a normal pattern here in Barbados. We have been getting a few showers lately and we just had a pretty decent one a few minutes ago. I actually think we're going to have a very wet rainy season. It's just a hunch.

LATER TONIGHT PER TRENDS OBSERVED IN RECENT SATELLITE IMAGERY AND
LATEST MODEL DATA. STILL COULD SEE A FEW SHOWERS POP UP OVER
SOUTHWEST PR LATER THIS AFTERNOON IN COMBINATION WITH INTENSE
HEATING AND SEA BREEZE CONVERGENCE. MOISTURE OVER THE LEEWARDS
SHOULD PASS OVER CARIBBEAN WATERS TONIGHT BRINGING SCT-BKN CLOUDS
AND A BIT MORE SHRA ACTIVITY BUT NOT EXPECTING MUCH OVER LAND
AREAS.

IT REMAINS RELATIVELY DRY THROUGH TUE WITH ANOTHER SMALL SURGE IN

SHOW LARGE DISCREPANCIES WITH THE TIMING OF THIS MOISTURE SURGE
WITH THE GFS THE FASTEST OF THE MODELS AND THE EUROPEAN THE
SLOWEST AND THE NAM IN BETWEEN. UNDER A STRONG SUBSIDENT PATTERN
ASSOCIATED WITH H7-H5 HIGH NO MORE THAN ISOLD POPS CAN BE

LARGE CUTOFF LOW DEVELOPING NORTH OF 30N WITH TROF AXIS EXTENDING
