Western Caribbean disturbance unlikely to develop this week
Posted by: Dr. Jeff Masters, 4:57 PM GMT on June 07, 2009 +2
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.

Thats is part of the SW Car. system it looks like is trying to develop. If shear still decending, still have a chance to develop, but right now is too much shear over it.


shear decreasing 5 to 10 over area with further slow decreasing over time

Funny...

Some real strong T-storms earlier, huh? Had hail and a lot of gusty winds.

Ah, thanks. I left the room for two minutes and missed that part.

I still think we're a few days at the very least from good enough conditions for any real development but watch me be wrong, lol

I was at work in West Palm when the storms passed through...didn't know we had hail in our area.

Guys, did y'all know that the NHC has labled our SW Carib disturbance as a test region? Doesn't that typically lead to an invest declaration soon eough? Somebody on here told me a short while ago that it will. :)


Who knows. I'm really interested to see if some of this strong convection that has recently fired up, will persist overnight.

A Blog fav..

A hurricane's "hot towers" can increase its intensity by adding power to boost the storm's heat engine. For the first time, research meteorologists have run complex simulations of these phenomena using a very fine temporal resolution. They have combined this new simulation data with satellite observations to study the innerworking of the "hot towers" in never-before-seen detail.

Despite our recent convection burst I still say that this wont develop. Its just a temporary convective complex. Should be gone by tomorrow.
