Gulf Of Panama

[Sanibel]

Whoa! Where did this suddenly come from?

Looks to me as if it will be in the Pacific soon, trucking west.

[Sanibel]

1) Agreed, EPAC-bound.

2) Think it is an Atlantic entity that suddenly formed all the way over here west at Panama.

TROPICAL WEATHER DISCUSSION
NWS TPC/NATIONAL HURRICANE CENTER MIAMI FL
205 PM EDT MON AUG 24 2009

A TROPICAL WAVE IS ALONG 74W S OF 20N MOVING W 15-20 KT. THIS
WAVE LIES IN A BROAD AREA OF DEEP LAYER MOISTURE THAT RANGES
FROM THE COAST OF VENEZUELA TO ERN PANAMA. LOW-LEVEL CYCLONIC
FLOW IS ALSO BROAD OVER THIS SAME AREA. DUE TO THE BROAD SURFACE
FLOW...CONFIDENCE IN THE EXACT LOCATION OF THE WAVE IS LOW AND
THE WAVE MAY BE FARTHER WEST. SCATTERED MODERATE CONVECTION IS
FROM 13N-15N BETWEEN 69W-72W. SCATTERED MODERATE/ISOLATED STRONG
CONVECTION IS FROM 9N-15N BETWEEN 76W-82W.

THE CARIBBEAN SEA...
ISOLATED SHOWERS/THUNDERSTORMS ARE N OF HONDURAS FROM 16N-18N
BETWEEN 82W-89W. THIS ACTIVITY MAY BE ENHANCED BY THE BROAD
CYCLONIC FLOW AROUND THE TROPICAL WAVE ALONG 74W. THE TROPICAL
WAVE IS ALSO ENHANCING SHOWERS/THUNDERSTORMS ACROSS THE SW AND S
CENTRAL CARIBBEAN...SEE ABOVE. THIS ACTIVITY IS ALSO ENHANCED BY
SURFACE CONVERGENCE NEAR THE E PACIFIC ITCZ AND A 1007 MB LOW
OVER PANAMA NEAR 8N78W. DRY AIR AND SUBSIDENCE ALOFT AROUND THE
UPPER LEVEL HIGH OVER CUBA NEAR 23N80W IS BRINGING GENERALLY
FAIR WEATHER ACROSS THE REMAINDER OF THE CENTRAL CARIBBEAN. A
FEW ISOLATED SHOWERS/POSSIBLE THUNDERSTORMS ARE ACROSS PUERTO
RICO AND THE LESSER ANTILLES DUE TO UPPER LEVEL DIFFLUENCE
BETWEEN AN UPPER LEVEL LOW IN THE ATLC NEAR 26N63W AND AN UPPER
LEVEL HIGH TO E NEAR 19N45W. EXPECT A TROPICAL WAVE CURRENTLY
ALONG 56W TO REACH THE NE CARIBBEAN LATER TONIGHT.

No one is paying attention to this system but it appears to be quietly trying to do something

[srainhoutx]

This is the area that the NOGAPS wanted to bring toward the Yucatan a few days ago.

[KWT]

Sure looks like its wrapping up rapidly but its probably only going to have time to become a TD, still it looks like it might be a quickfire system, should be a system in the EPAC though if it keeps this up.

The GFS is forecasting that it will bring some moderate to heavy rainfall to Central America, I hope it won't be too heavy but certainly we need that rain because this year we've had below average rainfall (Typical of an El Niño year).

Whoa! Where did this suddenly come from?

This wave flared up pretty good as it was passing over Trinadad a couple of days ago and the Nam has been bringing it a little NW, sort of up the spine of Central America for 3 or 4 days now. looks like it has it a little more on the Caribbean side this run.

I thought this was the thread for that area? Looks EPAC but who knows

[tailgater]

A little more 850 vorticity than 92L

[Sanibel]

This is a cool lesson in Panamanian correolis being too weak to spin it up unless it heads north.


Even if it doesn't form it makes you wonder about SW Caribbean favorability in a northward track trough year.

[HURAKAN]

Nothing at the surface and moving quite fast to the west. See ya in the EPAC!

SPECIAL TROPICAL WEATHER OUTLOOK
NWS TPC/NATIONAL HURRICANE CENTER MIAMI FL
555 PM EDT MON AUG 24 2009

FOR THE NORTH ATLANTIC...CARIBBEAN SEA AND THE GULF OF MEXICO...

SPECIAL OUTLOOK ISSUED TO ADD DISCUSSION OF AREA IN THE SOUTHWESTERN
CARIBBEAN.

UPDATED...A BROAD AREA OF LOW PRESSURE LOCATED OVER THE SOUTHWESTERN
CARIBBEAN SEA IS PRODUCING SCATTERED SHOWER AND THUNDERSTORM
ACTIVITY. ANY FURTHER DEVELOPMENT OF THIS SYSTEM SHOULD BE SLOW TO
OCCUR DUE TO PROXIMITY TO LAND. REGARDLESS OF DEVELOPMENT...HEAVY
RAINFALL IS POSSIBLE OVER NICARAGUA...COSTA RICA...AND PANAMA
TONIGHT AND TUESDAY AS THE LOW MOVES WESTWARD AT 20 TO 25 MPH.
THERE IS A LOW CHANCE...LESS THAN 30 PERCENT...OF THIS SYSTEM
BECOMING A TROPICAL CYCLONE DURING THE NEXT 48 HOURS.
