THE NATIONAL WEATHER SERVICE IN SAN JUAN HAS EXTENDED THE

* URBAN AND SMALL STREAM FLOOD ADVISORY FOR MINOR FLOODING OF POOR
DRAINAGE AREAS IN
FOR THE FOLLOWING MUNICIPALITIES...

IN PUERTO RICO
BAYAMON...COROZAL...NARANJITO...TOA ALTA...TRUJILLO ALTO...VEGA

DOPPLER RADAR SHOWS MODERATE TO LOCALLY HEAVY RAINFALL WILL CONTINUE
OVER THE NEXT FEW HOURS ACROSS THESE AREAS.

MOST FLOOD DEATHS OCCUR IN AUTOMOBILES. NEVER DRIVE YOUR VEHICLE INTO
AREAS WHERE THE WATER COVERS THE ROADWAY. FLOOD WATERS ARE USUALLY
DEEPER THAN THEY APPEAR. JUST ONE FOOT OF FLOWING WATER IS POWERFUL
ENOUGH TO SWEEP VEHICLES OFF THE ROAD. WHEN ENCOUNTERING FLOODED
ROADS MAKE THE SMART CHOICE...TURN AROUND...DONT DROWN.

MONDAY AFTERNOON...COMPUTER MODELS SUGGEST DRIER AIR WILL MOVE
OVER THE LOCAL AREA BEHIND THE COLD FRONT...WHICH WILL ALLOW FOR
SOME CLEARING SKIES AND MAYBE SOME SUNSHINE. HOWEVER...COMPUTER
MODELS SUGGEST THAT A SIGNIFICANT SURGE OF MOISTURE WILL MOVE BACK
TO OUR LOCAL AREA TUESDAY AND WEDNESDAY. GFS COMPUTER MODEL IS THE
MOST AGGRESSIVE ONE...BRINGING THE POTENTIAL FOR HEAVY RAINFALL
ACROSS THE LOCAL AREA. STAY TUNED FOR FURTHER INFORMATION.

Yeah you're right glad to see that for you ... but how lucky you are Cycloneye, you and Msbee compared to us in Guadeloupe . Meteo-France Guadeloupe expect a slight a very weak deteoriation of the weather tommorow morning with numerous clouds with scattered, localized and pretty isolated showers...nothing to stop a catastrophic drought . We continue to HOPE HOPE HOPE fingers crossed! in our desert

[cycloneye]

Here is what Puerto Rico and the Virgin Islands are going thru.

[abajan]

...And 2.2mm at Basse-Terre!!!!...Record of drought. Since december 20th 2009 ,only 40mmm (that's to say in 71 days, more than 2 months)...

We’ve had 26.9 mm (just a tad over an inch) at our airport since January 1. I smelt trouble brewing when I made this post last year but didn’t think it would be this bad.
The $64,000 question is: Will this El Niño be followed by a La Niña, causing just the opposite of what we’re presently experiencing?

Good afternoon or maybe good evening to all. It's seems that it has been a nice day in Puerto Rico today, as long as there is no flood cool and rainy is nice for me. Here in El Salvador the northerly winds have continued to day it's our 5th straight day with northerly winds and this morning was the coolest of those 5 and also today haa been the most windy.

San Salvador registered 17.6 °C (63.7 °F) this morning, and Las Pilas 6.6 °C (43.8 °F)
In the western part of the country gusts up to 50 km/h (31 mph) have been registered.

[HUC]

I don't know,abajan!!!I supposed that the nature will balance itself some time..In 1958,year of a terrible drought in the first three months of the year,the other months,specially may to october saw record of rain each months ( clled that year " an ITCZ year "....
So hope that all this drought will stopedsoon.

New low temperature record in San Juan

Also March being the driest month on average in Puerto Rico has broken rainfall records.See information below.

http://www.srh.noaa.gov/sju/?n=record100307

The cold front that stalled across Puerto Rico and the U.S. Virgin Islands from Friday evening March 5th, 2010 - through early Monday morning March 8th, 2010 - broke several records across both San Juan and Saint Thomas.

The high temperature at the Luis Muñoz Marin International Airport of 75 degrees March 7th, 2010 was the second coolest high temperature ever recorded in San Juan, and the high temperature of 75 degrees at the Cyril E. King Airport on Saint Thomas was the third coolest high temperature ever recorded there (the coolest high temperature ever recorded in San Juan was 73 degrees on January 18, 2000 and 72 degrees in Saint Thomas on October 27, 2007). Both records shattered the previous coolest high temperatures for the date of 80 and 79 degrees respectively. The high temperature of 77 in San Juan on Saturday March 6th, 2010, also broke the previous record for March 6th of 79 degrees, recorded back in 1969.
March is also statistically the driest month of the year across the local islands. Therefore it is of no surprise that several precipitation records also fell over the past weekend. New record precipitation totals for both San Juan and Saint Thomas were recorded on both March 6th and March 7th. A summary of the records set with this event are displayed below.

It looks like a break from the rain on monday before the front moves back northward on tuesday.

851 PM AST SUN MAR 7 2010

.UPDATE...THE COLD FRONT THAT BROUGHT RECORD RAINFALL AND RECORD
COOL TEMPERATURES ACROSS PUERTO RICO AND THE USVI IS FINALLY
MAKING PROGRESS SOUTHEASTWARD ACROSS THE LOCAL ISLANDS WITH
SHOWERS EXPECTED TO TAPER OFF SIGNIFICANTLY OVERNIGHT.

THE PUSH FROM THE MID TO UPPER LEVEL TROUGH ACROSS SOUTHWESTERN
ATLANTIC HELPED TO ACCELERATE THE MOVEMENT OF THIS FRONT THE PAST
FEW HOURS. WHILE AREAS OF LIGHT TO MODERATE RAINFALL WILL REMAIN
POSSIBLE THROUGH EARLY MONDAY MORNING...THERE NO LONGER EXISTS THE
POTENTIAL FOR WIDESPREAD HEAVY RAINFALL AND FLASH FLOODING ACROSS
THE LOCAL ISLANDS. FOR THIS REASON...THE FLASH FLOOD WATCH WAS
ALLOWED TO EXPIRE AT 6 PM AST.

LOTS OF LOW LEVEL STRATUS COULD BE SEEN ON SATELLITE EXTENDING
WELL BEHIND THIS COLD FRONT BEFORE THE SUN SET...AND EXPECT MOSTLY
CLOUDY SKIES TOMORROW AS A RESULT. HOWEVER...RAINFALL IS EXPECTED
TO BECOME MUCH MORE ISOLATED BEHIND THIS FRONT...WITH CONTINUED
UNSEASONABLY COOL TEMPERATURES EXPECTED FOR TOMORROW. COULD SEE A
RELATIVELY UNSTABLE WEEK AHEAD AS THIS FRONT IS EXPECTED TO LIFT
BACK ACROSS THE LOCAL ISLANDS ON TUESDAY AND WEDNESDAY.

&&

.AVIATION...MVFR CONDITIONS WILL CONTINUE AT TJBQ...TJSJ..TIST...AND
POSSIBLY TJMZ UNTIL BAND OF RAIN WITH FRONT MOVES FURTHER SOUTHEAST.
GUST WINDS TO INCREASE DURING PASSAGE AND HAVE ALREADY REACHED 35 KT
AT TIST BUT SHOULD COME DOWN AFT 08/06Z. SKIES REMAIN CLOUDY MUCH OF
UPCOMING DAY...BUT CONDS WILL IMPROVE UNTIL 08/21Z. LATEST 00Z
SOUNDING REVEALS LOW LEVEL WIND SHEAR NO LONGER PRESENT.

Additionally, no measurable rainfall has been recorded since 1.7mm of rain fell on February 3.
Feb 4-Mar 8 ** (and counting) 33 consecutive days
The island has seen sub-normal rainfall since March 2009 ( 12 months), and coming off the driest February ever recorded in the island nation ( total of 2.1mm)

While the other islands to the north (including Tobago) are also dealing with the drought and the very warm temperatures, Trinidad's temperatures have been noticeably more extreme, exacerbating the problem of the ongoing drought.

WEATHER SUMMARY FOR THE U.S. VIRGIN ISLANDS
NATIONAL WEATHER SERVICE SAN JUAN PR
500 AM AST MON MAR 8 2010

MOSTLY CLOUDY SKIES PREVAILED ACROSS THE U.S. VIRGIN ISLANDS DURING
THE OVERNIGHT HOURS. PERIODS OF LIGHT TO LOCALLY MODERATE RAINFALL
OCCURRED. LOW TEMPERATURES WERE IN THE LOWER TO MID 70S. IT WAS
BREEZY TO LOCALLY WINDY...WITH A GUSTY NORTH TO NORTHEAST WIND OF 15
TO 30 MPH.

SKIES WILL BE VARIABLY TO MOSTLY CLOUDY ACROSS THE LOCAL ISLANDS
TODAY. SCATTERED PASSING SHOWERS WILL OCCUR IN A FEW LOCATIONS. HIGH
TEMPERATURES WILL GENERALLY RANGE FROM THE MID 70S TO THE LOWER 80S.
IT WILL REMAIN BREEZY TO LOCALLY WINDY...WITH A GUSTY NORTH TO
NORTHEAST WIND OF 15 TO 30 MPH.

A COLD FRONT EXTENDING FROM THE NORTHERN LEEWARD ISLANDS WEST
SOUTHWEST ACROSS THE U.S. VIRGIN ISLANDS AND THEN CONTINUING
SOUTHWEST ACROSS THE CARIBBEAN EARLY THIS MORNING...WILL CONTINUE TO
SINK SOUTHEAST THROUGH TODAY...BEFORE BECOMING NEARLY STATIONARY
ACROSS THE SOUTHERN LEEWARD ISLANDS TONIGHT. THE REMNANTS OF THIS
BOUNDARY ARE THEN EXPECTED TO LIFT BACK TO THE WEST NORTHWEST
BEGINNING LATE TUESDAY. THE PROXIMITY OF THIS FEATURE AND ITS
ASSOCIATED MOISTURE TO THE LOCAL AREA WILL RESULT IN A GOOD DEAL OF
CLOUDINESS AND SOME SHOWERS OVER PARTS OF THE LOCAL ISLANDS DURING
THE NEXT FEW DAYS.

LONG PERIOD...NORTH SWELLS WILL CONTINUE TO AFFECT THE ATLANTIC
WATERS AND THE CARIBBEAN PASSAGES THROUGH AT LEAST TONIGHT AND WILL
COMBINE WITH MODERATE TO STRONG TRADE WINDS...TO PRODUCE HAZARDOUS
MARINE CONDITIONS...LOCALLY ROUGH SURF AND AREAS OF RIP CURRENTS. A
SMALL CRAFT ADVISORY REMAINS IN EFFECT FOR MOST OF THE LOCAL
ATLANTIC AND CARIBBEAN WATERS AND THE CARIBBEAN PASSAGES TODAY.

Off topic looks like another quake (6.0) has been felt in Turkey... unhopefully made 51 death.

[cycloneye]

Good morning to all.I am happy that at least some rain has reached Guadeloupe.But not satisfied that this front wont make it more southward towards the Southern Windwards.

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SAN JUAN PR
558 AM AST MON MAR 8 2010

.SYNOPSIS...
MID TO UPPER LEVEL SHORT WAVE TROUGH SWEEPING ACROSS THE LOCAL AREA
EARLY THIS MORNING WILL CONTINUE EASTWARD INTO THE WEST CENTRAL ATLANTIC
TODAY...RESULTING IN AN INCREASING WESTERLY UPPER LEVEL WIND FLOW ACROSS
THE REGION. A COLD FRONT EXTENDING FROM THE NORTHERN LEEWARDS ACROSS
PUERTO RICO AND THE VIRGIN ISLANDS...THEN INTO THE SOUTHERN CARIBBEAN
THIS MORNING... WILL CONTINUE TO SINK FURTHER SOUTHEAST THROUGH TODAY...
BEFORE STALLING ACROSS THE SOUTHERN LEEWARDS WHILE DISSIPATING. HOWEVER...
EXPECT THE FRONTAL REMNANTS TO RETROGRESS TO THE NORTHWEST BY LATE TUESDAY
AND INTO THE MIDDLE OF THE WEEK... THEN LINGER ACROSS PUERTO RICO AND
THE VIRGIN ISLANDS ONCE AGAIN DURING THE REMAINDER OF THE WEEK.

&&

.DISCUSSION...
LATEST SATELLITE IMAGERY SHOWED SIGNIFICANT AMOUNTS LOW TO MID
LEVEL CLOUDINESS BEING PUSHED SOUTHWARDS BY THE FAIRLY STRONG
AND COOL NORTHERLY WINDS ACROSS THE LOCAL ATLANTIC WATERS. THE
COLD FRONT AND ASSOCIATED BAND OF MOISTURE CONTINUED TO QUICKLY
SINK FURTHER SOUTHWARDS ACROSS PUERTO RICO AND THE VIRGIN ISLANDS
DURING THE EARLY MORNING HOURS. THIS WILL RESULT IN DECREASING
RAINFALL ACROSS THE ISLANDS AND SURROUNDING WATERS. EXPECT THIS
TREND TO CONTINUE DURING THE REST OF THE DAY...WITH GOOD COLD AIR
ADVECTION AND DECREASING DEW POINTS EXPECTED TO DROP TO NEAR 59
DEGREES DURING THE MORNING HOURS. EXPECT CONTINUED CLOUDINESS
ACROSS THE REGION DUE TO COLD AIR STRATIFORM CLOUDS...BUT RAINFALL
AMOUNTS WILL BE LESSER RAINFALL DURING THE DAY. THEREFORE EXPECT
ISOLATED TO SCATTERED SHOWERS ACROSS PARTS OF THE ISLANDS DURING
THE AFTERNOON... BUT NO WIDESPREAD RAINFALL...A A SLIGHT DRYING
TREND WILL OCCUR WITH THE COOL AIR ADVECTING FROM THE NORTH. SOME
EARLY MORNING FOG AND LOW STRATUS CLOUDS WILL BE APPARENT...IN HIGHER
ELEVATIONS AND VALLEYS OF PUERTO RICO DURING THE EARLY MORNING. AS
FOR THE REST OF THE WEEK EXPECT FRAGMENTS OF MOISTURE FROM THE FRONTAL
BOUNDARY TO RETURN TO THE LOCAL AREA BY THE LATTER PART OF THE WEEK.
THIS ALONG WITH LOCAL AND DIURNAL EFFECT SHOULD BE ENOUGH TO HELP
PRODUCE EARLY MORNING AND DIURNAL CONVECTION. DO NOT HOWEVER EXPECT
WIDESPREAD AMOUNTS OF RAINFALL ACROSS THE REGION AS WE HAVE HAD IN
RECENT DAYS WITH THE PASSAGE OF THIS FRONTAL SYSTEM.

&&

.AVIATION...EXPECT MVFR CONDITIONS TO PREVAIL ACROSS TKPK TODAY...
WITH BRIEF IFR CONDITIONS POSSIBLE IN AREAS OF RAIN AND SOME FOG
ASSOCIATED WITH THE FRONTAL BOUNDARY. OTHERWISE...EXPECT PREVAILING
VFR CONDITIONS ACROSS THE REST OF THE LOCAL ISLANDS AND TAF SITES...
BUT WITH BRIEF MVFR CONDITIONS AND LOCAL MOUNTAIN OBSCURATIONS POSSIBLE
IN PASSING SHRA. NORTHEAST SURFACE WINDS OF 15 TO 25 KNOTS SHOULD
CONTINUE IN SOME LOCATIONS...AT LEAST THROUGH THIS MORNING... PARTICULARLY
OVER TJBQ AND TISX...AS WELL AS TIST WHERE GUSTS TO 30+ KNOTS ARE STILL
POSSIBLE. THE MONTSERRAT VOLCANO REMAINS MAINLY QUIET AT THIS TIME.


&&

.CLIMATE...A RECORD DAILY MAXIMUM RAINFALL OF 1.05 INCH(ES) WAS SET AT
LUIS MUNOZ MARIN AIRPORT IN SAN JUAN/P.R. YESTERDAY MARCH 7 2010. THIS
BROKE THE OLD RECORD OF 0.28 THAT WAS SET IN 1985.
