NATIONAL WEATHER SERVICE SAN JUAN PR
1016 PM AST TUE MAY 25 2010
.UPDATE...SCATTERED SHOWERS AND ISOLATED THUNDERSTORMS PERSISTED
DURING THE EVENING HOURS ACROSS SOUTHEASTERN AND SOUTH SECTIONS OF
PUERTO RICO AS WELL AS ACROSS VIEQUES...CULEBRA AND THE SURROUNDING
COASTAL WATERS. ABUNDANT LOW LEVEL MOISTURE WILL CONTINUE TO STREAM
NORTHWARD ACROSS THE LOCAL ISLANDS FOR THE NEXT SEVERAL DAYS TO
ENHANCE THE AFTERNOON CONVECTION ACROSS PUERTO RICO AND THE U.S.
VIRGIN ISLANDS. NUMERICAL MODELS CONTINUE TO SUGGEST A VERY WET
WEATHER PATTERN FOR THE NEXT FEW DAYS...ESPECIALLY THURSDAY AND
FRIDAY. THE PROXIMITY OF A LOW PRESSURE SYSTEM WILL INCREASE THE
MOISTURE AND THE INSTABILITY ACROSS THE REGION...ENHANCING THE
DIURNAL CONVECTION TO RESULT IN LOCALIZED HEAVY RAINFALL AMOUNTS
OVER THE LOCAL ISLANDS. THEREFORE...URBAN AND SMALL STREAM FLOODING
WILL BE LIKELY. DUE TO ALREADY SATURATED SOILS...LOCAL RESIDENTS AND
EMERGENCY MANAGEMENT OFFICIALS ARE ENCOURAGED TO MONITOR THIS
DEVELOPING WEATHER SITUATION FOR THE END OF THE WEEK. ONLY MINOR
CHANGES WERE DONE TO THE PREVIOUS FORECAST PACKAGE.
.AVIATION...SHRA WILL CONTINUE TO AFFECT TIST...TISX...TJPS AND TJSJ
DURING THE REST OD THE EVENING HOURS. THEREFORE...MVFR CONDS AND
BRIEF MTN OBSCURATIONS ARE EXPECTED AT LEAST UNTIL 26/03Z IN THOSE
TAF SITES. PREVAILING VFR CONDS WITH PASSING SHRA ARE EXPECTED FOR
THE REST OF THE TAF SITES. LOW LEVEL WINDS WILL CONTINUE FROM
THE SOUTHEAST BTW 5-10 KTS...WITH HIGHER GUSTS IN PASSING SHRA.

Re: Caribbean - CA Weather=A wet week for most of Caribbean-CA
Hey Cycloneye, I see you're still online. I'm awake trying to decide if to block up my gate to keep out flood waters during the night. It;s been raining steadily for about an hour though not heavy in my location yet. The convection between Trinidad and Tobago is really bursting up right now. Trying to figure out whether this will move NW as it usually does, and give me a little ease up tonight. Judging from the lack of winds, it might just continue due West. 
Gonna be a long night....

Re: Caribbean - CA Weather=A wet week for most of Caribbean-CA
It's another cloudy morning in San Salvador and it's also windy, at this time it is not raining in here but there are other places (especially in the east part of the country) that have begun the day with heavy rains. Take a look at this picture, this was taken from my window and look how foggy it was:

Re: Caribbean - CA Weather=A wet week for most of Caribbean-CA
The SNET issued today a special advisory because of very significant wave heights in the salvadorian coast enhanced by the low in the Pacific, this waves are expected to peak on Thursday. This is the expected wave heights and speed in the different sections of El Salvador coast:
Ahuachapan and Sonsonate (first fifth of the coast from west to east): 4.9 m (16 ft) and 46 km/h (29 mph)
La Libertad (second fifth from west to east): 5.6 m (18 ft) and 62 km/h (39 mph)
La Paz and San Vicente (central fifth of the coast): 5.3 m (17 ft) and 50 km/h (31 mph)
Usulutan (fourth fifth from west to east): 4.8 m (15 ft) 42 km/h (26 mph)
San Miguel and La Union (last fifth of the coast): 4 m (13 ft) 32 km/h (20 mph)
The NHC mentions these wave on the TWD too but they are forecasting shorter waves:
ANOTHER TRAIN OF LONG PERIOD...17-19 SECOND...SWELLS WITH DEEP
WATER WAVE HEIGHTS OF 7-9 FT HAS ARRIVED ALONG THE COAST OF
CENTRAL AMERICA AND MEXICO AND WILL PUSH FURTHER N...IMPACTING
THE SRN GULF OF CALIFORNIA AND NORTHERN BAJA CALIFORNIA LATER
TODAY. S TO SW WIND WAVES ON TOP OF THE EXISTING LONG PERIOD
SWELL IS PUSHING SIGNIFICANT WAVE HEIGHTS TO 12 FT TO THE SOUTH

SPECIAL FEATURE ABOVE.

Re: Caribbean - CA Weather=A wet week for most of Caribbean-CA
Important discussion by HPC about this rain event.
TROPICAL DISCUSSION - INTERNATIONAL DESKS
NWS HYDROMETEOROLOGICAL PREDICTION CENTER CAMP SPRINGS MD
637 AM EDT WED MAY 26 2010
PRELIMINARY DISCUSSION FOR PUERTO RICO AND THE USVI. AT MID/UPPER
LEVELS A BROAD/LOW AMPLITUDE TROUGH REMAINS NORTH OF THE
ISLANDS...WHILE A RIDGE EXTENDS ACROSS THE ISLAND CHAIN TO THE
EASTERN CARIBBEAN...FAVORING A MID/UPPER LEVEL SOUTHWESTERLY FLOW
ACROSS HISPANIOLA-PUERTO RICO-USVI. A SHORT WAVE TROUGH TO THE
WEST IS ROUNDING THE BASE OF THE LONG WAVE AXIS...MOVING ACROSS
THE CAYMAN ISLANDS/JAMAICA INTO THE SOUTHERN CARIBBEAN. MODELS
CONTINUE TO SHOW THIS PERTURBATION LIFTING ACROSS HISPANIOLA TO
PUERTO RICO DURING THE NEXT 36-42 HRS. AS THE WAVE LIFTS...THEY
CONTINUE TO SHOW REPOSITIONING OF THE SUBTROPICAL JET
CORE...BRINGING BETTER UPPER LEVEL DYNAMICS TO THE FORECAST AREA.
AT LOW LEVELS THE FLOW WILL START FROM THE SOUTH-SOUTHEAST...BUT
THROUGH FRIDAY MORNING THEY ARE EXPECTED TO VEER TO THE
SOUTH-SOUTHWEST. A HIGH DIRECTIONAL SHEAR ENVIRONMENT IS EXPECTED
THROUGH THURSDAY AFTERNOON...WHILE ON FRIDAY TO SATURDAY THE
MODELS SHOW WEAK SPEED SHEAR AS WINDS BECOME SOMEWHAT MORE UNIFORM
WITH HEIGHT. PWS REMAIN HIGH...AND ARE FORECAST TO SURGE THROUGH
FRIDAY-SATURDAY BEFORE A DRY SLOT ENTERS THE ISLAND CHAIN/VIRGIN
ISLES-PUERTO RICO EARLY NEXT WEEK. THIS WILL COINCIDE WITH A
DECREASE IN MJO ACTIVITY.
THE EVOLVING PATTERN IS FORECAST TO SUSTAIN A GRADUAL SURGE IN
CONVECTION ACROSS PUERTO RICO AND THE USVI. MODELS ARE NOW IN
BETTER AGREEMENT ON THE TIMING OF THIS EVENT... MAINTAINING
CYCLE-TO-CYCLE CONTINUITY. ALTHOUGH THE MODELS SEEM TO AGREE ON
THE WHEN...THEY DIVERGE ON THE WHERE. THE GFS SHOWS CONVECTION
DEVELOPING TO THE NORTH OF THE FORECAST AREA BY
FRIDAY-SATURDAY...WHILE THE ECMWF DEVELOPS A PRECIP BOMB TO THE
SOUTH OVER CARIBBEAN WATERS. BUT WE MIGHT BE SPLITTING HAIRS...AND
A COMPROMISE BETWEEN THESE MODELS WILL PUT THE CONVECTION RIGHT ON
TOP OF THE ISLANDS. RAINFALL AMOUNTS ARE EXPECTED IN THE RANGE OF
2-3 INCHES (50-75MM)...WITH LOCALIZED MAXIMA OF 6-8 (150-200MM).
AS THE FLOW TAKES A MORE SOUTHWESTERLY COMPONENT BY FRIDAY...THIS
IS LIKELY TO PUT THE SAN JUAN METRO AREA AT RISK OF HEAVY AMOUNTS.

EASTWARDS FROM HISPANIOLA TOWARD THE MONA PASSAGE THIS EVENING. THIS
MOISTURE IS ASSOCIATED WITH A BROAD TROUGH ACROSS THE CENTRAL
CARIBBEAN...AND ALSO WITH AN AREA OF LOW PRESSURE OVER THE WEST
ATLANTIC. THESE FEATURES WILL CONTINUE TO CREATE A FAIRLY LIGHT BUT
PERSISTENT MOIST SOUTHERLY FLOW ACROSS THE REGION OVER THE NEXT FEW
DAYS. FOR THURSDAY AFTERNOON THROUGH SATURDAY...THE TROUGH ACROSS
THE CENTRAL CARIBBEAN WILL EXTEND TO NORTH OF THE U.S. VIRGIN
ISLANDS PULLING COPIOUS MOISTURE WITH IT INTO THE LOCAL ISLANDS.
THIS WILL ACT TO ENHANCE RAINFALL ACROSS THE REGION...ESPECIALLY
THURSDAY AND FRIDAY. THERE IS CONSIDERABLE POTENTIAL FOR TORRENTIAL
RAINFALL...WIDESPREAD URBAN AND SMALL STREAM FLOODING...MAIN STREAM
RIVER RISES AND MUDSLIDES IN SATURATED SOILS. DUE TO ALREADY
SATURATED SOILS...LOCAL RESIDENTS AND EMERGENCY MANAGEMENT
OFFICIALS ARE ENCOURAGED TO MONITOR THIS DEVELOPING WEATHER
SITUATION FOR THE NEXT FEW DAYS. A FLASH FLOOD WATCH WILL BE IN
EFFECT FOR ALL OF PUERTO RICO AND THE U.S. VIRGIN ISLANDS

that's awfull Cycloneye...meanwhile the Leewards Islands especially the Northern Leewards islands should be on yellow alert during the next couple of hours today given Meteo-France Guadeloupe as a strong deterioration of the weather is expected An area of showers and thunderstorms will provide a very good deal of rain and tstorms especially tommorow and during the weekend! Guadeloupe is concerned too (and should be in yellow alert tommrow) with this episode but seems that the main activity will be foccus on the Northern Leewards. Let's follow closely as usual what could happen from this possible event.Gustywind
