Western Caribbean disturbance unlikely to develop this week

An area of disturbed weather is bringing some heavy rains to Nicaragua and Honduras and the adjacent waters of the Western Caribbean. This disturbance has generated 2 - 3 inches of rain over these countries over the past two days, and is likely to bring an additional 2 - 3 inches of rain to northeastern Honduras and Nicaragua over the next two days. The disturbance is expected to gradually drift northwards, bringing heavy rain to the Cayman Islands, Jamaica, and Cuba by Monday or Tuesday. The disturbance is under prohibitively high wind shear of 30 - 40 knots, and is not a threat to develop today or Monday. Some of the computer models are predicting wind shear may fall low enough to allow development of this system 4 - 7 days from now, but the models have been rather inconsistent in the location and timing of any such development. For now, the chances of a tropical depression forming from this disturbance within the next week appear low, less than 30%.

I'll have an update Monday.

Convection always does this during the day you know that very well because of the Durinal cycles. This always happens with weak systems.

Greetings again,

I just got an email from Barometer Bob. I send him copies of my updates as well.

He wants to have me on as a call in guest sometime when we have the good chance of a developing system.

Gotta call and work out the details though.



Congrats StormW! Be sure and let us know when so we can tune in.

Strongly disagree. 2004 was an El Nino year and so was 1992. 2004 had late season cold fronts as well.



Thanks

Shear is about 30 kts and is not changed over the past 24 hours.

still to much shear in the area,my guess for the first named TC is june 22,around the 120-168hr period shear over the west carib and GOM should be much lower and the chances of a disturbance in the area w/be rising,IMO

Energy / Cyclonic turning in the lower levels that was not present yesterday. Vorticity / Energy in the lower atmosphere is what spawns surface lows.

Looks like the trough is breaking free from the blob...we should know soon huh?


I think the only reason right now there is a blob is because of the trough,its whats causing the wx in that area.....not a surface low

I think at some point this system will move into the gulf and give plenty of rain to the gulf coast just where.


I sure hope so, have it come into Central Texas as a weak tropical system and dump a ton of rain. We are at the highest drought level you can be at...and it's getting worse.

This is why the AOI has been able to maintain a large area of cold cloudtops in the face of the shear. The amount precipitable water in the SW Carribean jumps off the charts in the last 24 hours of this loop.


And it's soon to have the wave.
