Is all tranquil now after that. Let's see if there will be some more rainbands moving thru during the rest of the night.

Yep. As soon as I saw the satellite loop, I knew PR was getting some pretty intense weather. Looks like Hispaniola is getting quite a bit too.

Good morning.Lingering moisture after the passage of wave will cause showers to fall today.


AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SAN JUAN PR
512 AM AST SUN JUL 24 2011

.SYNOPSIS...AN ACTIVE TROPICAL WAVE NOW LOCATED OVER THE MONA
PASSAGE WILL CONTINUE TO MOVE WEST AND AWAY FROM OUR LOCAL
FORECAST AREA THIS MORNING. RESIDUAL MOISTURE...LOCAL EFFECTS AND
UNSTABLE UPPER LEVEL CONDITIONS WILL HELP IN THE DEVELOPMENT OF
LATE MORNING-EARLY AFTERNOON CONVECTION. A SURFACE HIGH PRESSURE
WILL CONTINUE TO BUILD OVER THE AREA...TIGHTENING THE PRESSURE
GRADIENT ACROSS THE REGION AND THEREFORE INCREASING THE WIND
VELOCITY ACROSS THE LOCAL FORECAST AREA.

&&

.DISCUSSION...DOPPLER RADAR AND SATELLITES IMAGES HAVE STARTED TO SHOW
A SIGNIFICANT DECREASE ON THE STRONG THUNDERSTORMS AND HEAVY SHOWER
COVERAGE. AT THIS MOMENT THE DOPPLER RADAR SHOWS ONLY ISOLATED TO
LOCALLY SCATTERED SHOWERS MOVING ACROSS THE LOCAL WATERS. ALTHOUGH
PLAYED WITH THE IDEA OF DROPPING THE FLASH FLOOD WATCH BUT DECIDED
NOT TO DUE TO THE INTERACTION BETWEEN THE LINGERING MOISTURE AND
LOCAL EFFECTS FROM MID MORNING THROUGH AFTERNOON HOURS. THE AREA
MOST AFFECTED BY THESE SHOWERS AND THUNDERSTORMS WILL BE THE
WESTERN PORTIONS AND NORTHERN HALF OF PUERTO RICO. ALSO UPPER
LEVEL CONDITIONS REMAIN FAVORABLE THROUGH AT LEAST TONIGHT.

&&

.AVIATION...VFR CONDITIONS WILL PREVAIL ACROSS ALL TAF SITES
THROUGH AT LEAST 24/16Z. BRIEF PERIODS OF MVFR CONDITIONS ARE
POSSIBLE BETWEEN 24/16Z-24/22Z ACROSS..TJSJ..TJMZ...TJBQ. WINDS WILL
BE MAINLY FROM THE EAST AT 10 TO 15 KTS.

THROUGH AT LEAST MONDAY AS THE PRESSURE GRADIENT WILL REMAIN TIGHT
ACROSS THE LOCAL REGION. BORDERLINE SMALL CRAFT ADVISORY CONDITIONS

Hi guys, it seem that El Salvador and other regions on the Pacific coast of Central America are under the period known as canicula or "dog days" (in Central America is a period of 5 days or more with above normal temps and below normal rains). In El Salvador we've had 5 days of above normal temperatures and yesterday was the driest day in the country since June 2, only one station registered rainfall and it was a little amount (3 mm/0.12 inch). It seems that on Tuesday we will return to normal as the models are forecasting more rain for the Pacific coast of the region.

.SYNOPSIS...TROPICAL WAVE NOW LOCATED OVER THE HISPANIOLA WILL
CONTINUE TO MOVE WESTWARD AND AWAY FROM THE LOCAL ISLANDS THIS
AFTERNOON. HOWEVER...AN UNSTABLE WEATHER PATTERN WILL CONTINUE
ACROSS THE FORECAST AREA THROUGH AT LEAST TONIGHT AS A RESULT OF
FAVORABLE UPPER LEVEL DYNAMICS AND LINGERING MOISTURE ASSOCIATED
WITH THIS WAVE.

&&

.DISCUSSION...TOTAL PRECIPITABLE WATER IMAGERY CONTINUES TO SHOW
A MAXIMUM OF DEEP LAYER MOISTURE ACROSS THE LOCAL AREA. THIS
LINGERING MOISTURE ASSOCIATED WITH AFOREMENTIONED TROPICAL WAVE
WILL CONTINUE TO COMBINE WITH FAVORABLE UPPER LEVEL DYNAMICS...
LOCAL EFFECTS AND DIURNAL HEATING TO PRODUCE SHOWERS AND THUNDERSTORMS
ACROSS THE NORTHERN SLOPES AND WESTERN PUERTO RICO THIS AFTERNOON.
HOWEVER...THE FLASH FLOOD WATCH HAS BEEN CANCELLED DUE TO THE LACK
OF ANY PROLONGED HEAVY RAINFALL DURING THE PAST 12 HOURS AND THE
EXPECTED FAIRLY RAPID MOVEMENT OF SHOWERS AND THUNDERSTORMS THIS
AFTERNOON. THESE AFTERNOON SHOWERS AND THUNDERSTORMS SHOULD
DISSIPATE AROUND SUNSET...LEAVING PARTLY CLOUDY SKIES ACROSS THE
LOCAL AREA. FOR TONIGHT...ISOLATED SHOWER ACTIVITY STILL EXPECTED
ACROSS THE EASTERN HALF OF PUERTO RICO AS WELL AS ACROSS THE
REGIONAL WATERS.

MODEL GUIDANCE INDICATES TOTAL PRECIPITABLE WATER DROPPING BELOW
2.0 INCHES THROUGH MID WEEK. HOWEVER...AVAILABLE MOISTURE WILL
COMBINE WITH LOCAL EFFECTS AND DIURNAL HEATING TO PRODUCE SHOWERS
AND ISOLATED THUNDERSTORMS EACH AFTERNOON. NEXT MOISTURE SURGE IS
EXPECTED TO REACH THE LOCAL AREA THURSDAY THROUGH SATURDAY...
BRINGING ONCE AGAIN BETTER CHANCE OF SHOWER AND THUNDERSTORM
ACTIVITY ACROSS THE LOCAL ISLANDS.

517 AM AST MON JUL 25 2011

.SYNOPSIS...HIGH PRESSURE ACROSS THE CENTRAL ATLANTIC WILL DOMINATE
THE LOCAL WEATHER TODAY. THE NEXT TROPICAL WAVE IS FORECAST TO
REACH OUR LOCAL WATERS ON FRIDAY.

&&

.DISCUSSION...THE DOPPLER RADAR IS ONLY SHOWING A FEW PASSING
SHOWERS ACROSS THE LOCAL WATERS. A FEW OF THESE SHOWERS BRUSHED
THE NORTHERN COAST OF PUERTO RICO...WITHOUT PRODUCING ANY
SIGNIFICANT RAINFALL ACCUMULATIONS.

A SURFACE HIGH PRESSURE WILL CONTINUE TO BUILD OVER THE LOCAL
REGION BRINGING A DRYER AIR MASS OVER THE LOCAL REGION. THIS WILL BE
THE LIMITING FACTOR FOR SHOWER AND THUNDERSTORMS DEVELOPMENT.
ENOUGH MOISTURE WILL BE AVAILABLE FOR ISOLATED TO SCATTERED
SHOWERS AND PROBABLY ONE OR TWO THUNDERSTORMS TO DEVELOP MAINLY
OVER THE WESTERN PORTIONS OF PUERTO RICO. SATELLITES IMAGES ARE
SHOWING A SLIGHT INCREASE ON MOISTURE MOVING TOWARD THE LOCAL
FORECAST AREA THIS EVENING. THIS WILL SLIGHTLY INCREASE THE CHANCE
OF SHOWERS ACROSS THE LOCAL WATERS AND EASTERN PORTIONS OF PUERTO
RICO AND ADJACENT ISLANDS.

THERE ARE TWO FEATURES THAT COULD INCREASE THE CHANCES OF SHOWERS
AND THUNDERSTORMS THIS WEEK. ON TUESDAY NIGHT A SURFACE TROUGH
ASSOCIATED TO A MID LEVEL LOW NORTHEAST OF THE REGION...WILL MOVE
ACROSS THE REGION. THE SECOND WEATHER FEATURE WILL A TROPICAL WAVE
THAT IS FORECAST TO REACH OR LOCAL FORECAST AREA ON FRIDAY

Caribbean and Central American friends,we have to prepare if you have not done so already,because it looks like things will be very active for this part of the Atlantic Basin during the peak of the season.Here is what Crown Weather says about what to expect.

http://www.crownweather.com/?page_id=4557

The latest indications continue to point to the potential for a very busy August, September and October across the Atlantic Basin. The latest European seasonal model continues to point to significantly lower than average pressures across the western Atlantic, Caribbean and eastern Gulf of Mexico. This lower than average pressure signal seems to point to numerous tropical cyclones tracking into the western half of the Atlantic Basin during August, September and October. For what it’s worth, the CFS model for Friday, August 26th is forecasting three significant tropical cyclones going at once across the Atlantic. The exact details of the model shouldn’t be trusted, however, the overall trend of a significant increase in tropical cyclone activity should be heeded.

So, today would be a very good day to go over your hurricane preparedness kit and if you need supplies and can afford it, go to your local supermarket, your local Target, Wal-Mart or Lowe’s and purchase what you need. If you are looking for lists of what should be in your hurricane preparedness kit, go to http://www.onestorm.org. This is a really good reference website and I highly recommend it!! Also, go over your homeowners or renter’s insurance and make sure you are properly covered. If you do not have flood insurance, get it!! Most homeowners/renter’s insurance policies do not

Strong showers and isolated tstorms are spreading on Guadeloupe during the last 3 hours. Yellow alert has been requiered for Guadeloupe and Martinica fos a risk of strong showers and tsorms. Seems that numerous cells of tstorms near Barbados are moving near the northern Windwards and also the Leewards islands. I will keep you informed as usual. Be safe and dry.

Yes Gusty, hard rain here in St Lucia. It's as if someone just switched the lights off, it has gone so dark. Had more rain this evening than we had from Invest 90.
