Caribbean - Central America Weather

[abajan]

Earlier I rang our weather hotline and discovered that a flash flood watch was issued at Noon and was to remain in effect until 4:00 p.m. The statement said that the duration of the watch would be extended if conditions were to warrant it. Anyway, right now there's just a light drizzle but it's still overcast.

Btw, the phone number is (Area Code: 246) 976-2376. Unless you have some vested interest here, please avoid calling it when a serious system like a tropical storm is threatening Barbados because (unless they have recently increased that line's carrying capacity, which I doubt) it tends to give a busy tone on such occasions.

EDIT: I subsequently learned that the flash flood watch was indeed discontinued at 4:00 p.m.

[expat2carib]

Dominica is getting a bad one right now. Gusty winds and heavy rain.

[expat2carib]

Off again. Nobody can tell me this is a organized -or organizing- system. It's short periods of on and off. I guess that what they call a disorganized system. Scattered.

[Gustywind]

Yellow alert has been required in Guadeloupe and Martinica too!
This feature is coming with its gustywinds and heavy rains. I was near Jarry (Baie-Mahault) there's just a moment...experiencing a first solid line of showers :eek. Hopefully things have calm down, but for info a gust has been reported at 40kts or 75km/h at Sainte-Anne (Guadeloupe). Given what my eyes have seen, i do not want to imagine Barbados under these squall line or line of showers. Disorganized system but very windy for sure. Looks like sheared but always there to bring a moderate convective activity.
I will keep you informed tonight as i'm leaving for a moment...

[caribsue]

All quiet here in Barbados nice cool breeze blowing and no shower for quite sometime now. Maybe I can get some work done tomorrow.... To my caribbean neighbours have a safe night.

[cycloneye]

Is quiet in San Juan in terms of no rain but the fresh breeze has mantained in the night hours.But tommorow it will be a variable day with scattered showers mixed with some strong gusty winds as the bulk of the system passes to our south.

[Gustywind]

How tenacious this thing is in spite of the shear... Nothern part has been seriously sheared but convective activity is trying to make a difficult comeback. Martinica is maybe experiencing a bit of this moderate bulk of convection.

Good morning fellow Caribbean friends.The sun has not peaked out this morning as the clouds are prevalent.The big mass of showers and thunderstorms will remain south of PR,but some bands may arrive later today.

WEATHER SUMMARY FOR THE U.S. VIRGIN ISLANDS
NATIONAL WEATHER SERVICE SAN JUAN PR
507 AM AST TUE JUL 21 2009

THE NWS DOPPLER RADAR DETECTED SCATTERED TO NUMEROUS SHOWERS AND
ISOLATED THUNDERSTORMS RACING ACROSS THE COASTAL WATERS OVERNIGHT
AND EARLY IN THE MORNING. FEW OF THEM MOVED INLAND ACROSS ST THOMAS
AND ST JOHN...BUT DUE TO THE RAPID MOVEMENT OF THE SHOWERS THE TOTAL
RAINFALL AMOUNTS WERE GENERALLY MINIMAL. THE WINDS WERE MOSTLY FROM
THE EAST SOUTHEAST AT 10 TO 15 MPH WITH STRONG GUSTY WINDS NEAR
SHOWERS AND THUNDERSTORMS. THE LOCAL TEMPERATURES EARLY IN THE
MORNING RANGED FROM THE UPPER 70S TO THE LOWER 80S.

THE OVERNIGHT AND EARLY MORNING SHOWER AND THUNDERSTORM ACTIVITY
WAS ASSOCIATED WITH A TROPICAL WAVE...LOCATED JUST ACROSS THE LOCAL
ISLANDS. THE WAVE AXIS WAS JUST ACROSS EASTERN PUERTO RICO EARLY IN
THE MORNING. A CLUSTER OF THUNDERSTORMS ASSOCIATED WITH THE LOW
LEVEL CIRCULATION WAS OBSERVED EARLY IN THE MORNING WELL SOUTH
SOUTHWEST OF ST CROIX. FAST MOVING SCATTERED TO NUMEROUS SHOWERS AND
ISOLATED THUNDERSTORMS WITH STRONG GUSTY WINDS...WILL CONTINUE
ACROSS THE SURROUNDING WATERS THIS MORNING. FOR THIS AFTERNOON...THE
MOISTURE ASSOCIATED WITH THIS WAVE IN COMBINATION WITH LOCAL ISLANDS
EFFECTS WILL INDUCE THE DEVELOPMENT OF SCATTERED SHOWERS AND
ISOLATED THUNDERSTORMS ACROSS THE REGION. THE TROPICAL WAVE WILL
CONTINUE TO TRACK RAPIDLY WESTWARD AND AWAY FROM THE LOCAL REGION
TONIGHT. WEATHER CONDITIONS WILL IMPROVE RAPIDLY LATE WEDNESDAY AS
DRIER AIR MOVES ACROSS THE LOCAL ISLANDS FROM THE EAST.

SUSTAINED WINDS UP TO 24 KNOTS WITH OCCASIONAL HIGHER GUSTS NEAR
STRONG THUNDERSTORMS AND SEAS UP TO 8 FEET WILL PREVAIL ACROSS THE
REGIONAL COASTAL WATERS UNTIL AT LEAST TONIGHT. SMALL CRAFT
ADVISORIES ARE IN EFFECT FOR ALL OF THE LOCAL COASTAL WATERS EXCEPT
FOR THE NEAR SHORE WATERS OF WESTERN PUERTO RICO.

Hi everbody and you Cycloneye . Us in Guadeloupe, are always under an yellow alert for strong showers and tstorms in spite of the decreasing activity of the twave. I was speaking in my last post about a gust reported at 40 kts yesterday night, but moreover the sea was rough and a strong wave has reached 5meters 20 . Otherwise, amounts of 60 to 65 millimeters have been measured by Meteo-France on the whole island.
Things are improving steadily on my area, wind is calm, the sun is trying to make a little apparition but the risk of showers and locally tstorms is a bit possible, so we stay on our guard for this morning.
Hey Luis, seems that you will experience some rain and gusty wind from this feature, be safe

[cycloneye]

It looks like we will get more rain than expected as it is climbing in latitud.

They should not ignore E Puerto Rico or the Virgins. Entire mass of clouds has moved north LOTS more than west in the last 4hours. Here is proof, a picture worth a million words:

[HUC]

Huge mass of showers,with SE flow,strong enough to push the clouds against the mountains..I don't know exactly orographics mechanisms of PRico,but seems a potential flood situation Luis?

[bvigal]

Oh, and I can still see circulation on the long-range radar loop, it's been obvious since 6:30 this morning. I don't care if a buoy at 15N 67W didn't measure W winds ... this is at about 16.3N 67W. So this thing is a low pressure, as far as I'm concerned, and is going to make some strong tstorms, lightning, damaging winds, flash flooding, etc. at least for parts of PR/DR, and whether it's "tropical" or not, doesn't really matter, does it?

You are correct about that.No matter what it is,we will see abundant precipitation.

whether it's "tropical" or not, doesn't really matter, does it?

I absolutely agree BVIGAL. The fact remains that the people on the ground will be experiencing conditions that could present a threat - if not to life - then to limb.
I think sometimes that those in larger countries may not appreciate the real challenges that we face in small nations. Our infrastructure is severely put to the test by extreme weather. It doesn't have to be a TC to cause loss of life and millions of dollars worth in damages.
So to my friends in Puerto Rico and surrounding territories, our thoughts and concerns are with you.
