TROPICAL WEATHER DISCUSSION FOR NORTH AMERICA...CENTRAL
AMERICA...GULF OF MEXICO...CARIBBEAN SEA...NORTHERN SECTIONS
OF SOUTH AMERICA...AND ATLANTIC OCEAN TO THE AFRICAN COAST
FROM THE EQUATOR TO 32N. THE FOLLOWING INFORMATION IS BASED
ON SATELLITE IMAGERY...METEOROLOGICAL ANALYSIS...WEATHER
OBSERVATIONS...AND RADAR.

BASED ON 0600 UTC SURFACE ANALYSIS AND SATELLITE IMAGERY THROUGH
WWWW UTC.

...TROPICAL WAVES...

TROPICAL WAVE IS FROM ALONG 60W/61W S OF 18N MOVING W NEAR 10
KT. THE AXIS OF THE WAVE IS ORIENTED WITHIN A MOISTURE MAXIMUM
OBSERVED IN TOTAL PRECIPITABLE WATER IMAGERY. A WEAK AND ILL
DEFINED LOW/MID LEVEL CIRCULATION IS ALONG THE WAVE NEAR 13N. SCATTERED SHOWERS/ISOLATED THUNDERSTORMS ARE FROM 12N-15N BETWEEN 60W-64W INCLUDING THE WINDWARD ISLANDS MOVING W AWAY
FROM BARBADOS.

Shear is abating in vicinity of the twave...

Another view of the two twaves near the Lesser Antilles...

[wxman57]

The one in the Caribbean is dying now. It's past its chance of development. The one to the east has diminishing convection. Development chances look very low. The east Atlantic is the place to watch for development.

[Sanibel]

The west basin has gone negative. Even the convection by Central America. Funny how it all turns off at once.


This is a rough hobby. Carribbean wave toast.

[Gustywind]

Decreasing trend... Looks like convection has fairly diminished.

[wxman57]

Perhaps the thread title could be changed to "Disturbance in Eastern Caribbean" so as not to confuse it with the other disturbance east of the Caribbean? This one's toast, though.

I agree. 50W or Central Atlantic (Disturbance E of The Caribbean), Wave of Africa... It's getting confusing with all this activity.

TORNADO IN WEST CENTRAL TRINIDAD
Sun Aug 9 2009

this is a video shot on Sun August 9/2009 near noon ... im not sure if the "tornado" actually did touch the ground since its not clear with this footage, but it was a large funnel cloud for certain. There were reports of hail in parts of Central Trinidad as well.
Tornadoes are fairly rare events on trinidad due to its small size, but have been increasing in their appearances over the last number of years. Of all the Eastern Caribbean Islands, (apart from puerto rico) trinidad is the most likely for a tornado to form since its a relatively larger island to the others.
They normally form on the west central parts of the island, since this part is the flattest area of the island .
Generally, the "tornado season" in trinidad is the months of september and october since these are the hottest and most humid times of the year when trade winds are at their weakest, allowing temperatures to sky-rocket into the mid 90s (locally higher) on the west coast.

But this is great footage,

[Gustywind]

Does not looking healthy but its neighbour just east of the islands is gaining a better sat appareance with expanding convection...

[drezee]

grenada looks to be getting poured on...that is deep convection right over the island

[Sanibel]

I think the central Atlantic wave stole the energy from this one.

Another tropical wave and an associated weak low pressure is passing through the Windward Islands. No development is imminent, however showers and clouds will continue to impact the islands.

THE NATIONAL HURRICANE CENTER IS ISSUING ADVISORIES ON TROPICAL
DEPRESSION TWO...LOCATED ABOUT 400 MILES WEST OF THE SOUTHERNMOST
CAPE VERDE ISLANDS.

A SMALL AREA OF LOW PRESSURE ASSOCIATED WITH A TROPICAL WAVE IS
PRODUCING DISORGANIZED SHOWERS AND THUNDERSTORMS OVER THE
SOUTHEASTERN CARIBBEAN SEA. DEVELOPMENT OF THIS SYSTEM...IF
ANY...IS EXPECTED TO BE SLOW TO OCCUR AS IT MOVES GENERALLY
WESTWARD AT 10 TO 15 MPH OVER THE SOUTHERN CARIBBEAN SEA DURING THE
NEXT COUPLE OF DAYS. THERE IS A LOW CHANCE...LESS THAN 30
PERCENT...OF THIS SYSTEM BECOMING A TROPICAL CYCLONE DURING THE
NEXT 48 HOURS.

SHOWER AND THUNDERSTORM ACTIVITY ASSOCIATED WITH A TROPICAL WAVE
LOCATED ABOUT 500 MILES EAST OF THE LESSER ANTILLES HAS DECREASED
THIS AFTERNOON AND EVENING. ANY DEVELOPMENT OF THIS SYSTEM IS
EXPECTED TO BE SLOW TO OCCUR AS IT MOVES WEST TO WEST-NORTHWESTWARD
AT 10 TO 15 MPH. THERE IS A LOW CHANCE...LESS THAN 30 PERCENT...OF
THIS SYSTEM BECOMING A TROPICAL CYCLONE DURING THE NEXT 48 HOURS.

I can't believe this little dude is still hanging in there. Still looks like has a small circulation and little burst is starting to pop. Wxman, I thought this thing was suppose to die? Are the wind currents going to keep it to close to S America for developement? Shear dosent look all that bad, just wrong direction I think.
