Caribbean disturbance 94L may develop early next week
Posted by: Dr. Jeff Masters, 20:11 GMT le 12 novembre 2010 +3
An area of disturbed weather (Invest 94L) has developed in the southern Caribbean off the coast of Colombia, and has the potential to develop into a tropical depression early next week. Satellite images show that 94L has a limited amount of heavy thunderstorms, but the activity is showing signs of organization, with several curved bands developing on the west side of 94L's center. Water vapor satellite images show a large amount of dry air lies to the north over the northern Caribbean, and this dry air may slow down development to a small degree. SSTs are warm, 29°C, and wind shear as analyzed by the University of Wisconsin CIMSS group is a moderate 10 - 15 knots.


Figure 1. Afternoon satellite image of 94L.

Forecast for 94L
The latest SHIPS model forecast predicts that wind shear will remain in the moderate range, 10 - 20 knots, through Sunday, then rise to the high range, 20 - 30 knots, Monday through Wednesday next week. The modest shear, warm SSTs, and relatively moist atmosphere should allow for some slow organization of 94L as it moves slowly westwards at 5 mph over the next two days. The models predict that the steering currents in the southern Caribbean will keep 94L moving generally westwards at about 5 mph for the next five days, which would bring the storm ashore over Nicaragua or northeast Honduras on Wednesday. Both the GFS and NOGAPS models show some modest development of 94L, and NHC is giving the system a 30% chance of developing into a tropical depression by Sunday. The Hurricane Hunters are on call to investigate 94L on Monday afternoon. At this time, it appears that 94L will only be a concern for Central America. I give 94L a 50% chance of eventually becoming Tropical Storm Virginie.

I'll have an update Saturday by 1pm EDT.

ANOTHER storm that doesn't affect the USA. Amazing. I was hoping this could go NNW and bring some rain to drought-stricken florida.

No, no, no, no, no!!!! I realize mid November is still technically Hurricane Season. But usually it is a pretty safe to book your cruise at this time!!

Good for you guys bad for us. I have to check but I think this is a record for Belize to have 3 named storms making landfall here in one year.

Do you think 94 will barely go over Honduras or go N of it?

Very rough surf off of DBS today and a lot the waves are breaking far from shore. Supposed to be even rougher tomorrow thanks to the low in the Atlantic.

well if you look at surface map i posted for 72 hr mark shows a cold front swing down into GOM that may become an important player also that said front should move down to yuc in a line ne ward up over fla but stall and become occulted so we have to watch a few things to be sure after the next 24 we will know more

No. It will be third, behind the 21 of 1933.
And still amazing to me that not one hurricane hit the USA Conus!

If 94L becomes Virginie we'd still be 3rd place, but we'd break the named storm tie with 1995 and 1887.

Still, its pretty extreme that 2 of the top 3 most active hurricane seasons have happened in the last 5 years.

Its possible that 2010 will end up with a final toll of 21-13-5. I think Walter will form at the very end of this month.

FWIW. While there has not been a 'Landfalling' US hurricane this year, Earl made a Direct hit on the Outer banks.

Still, we shouldn't mainly focus on how the US wasn't hit this year. Somehow the news finds it right to do that though. How about the fact out of the 19 storms we have had this year.. 12 of them made a landfall? Alex, Bonnie, Earl, Fiona, Hermine, Igor, Karl, Matthew, Nicole, Paula, Richard, and Tomas.

Did Tomas's eye hit St. Lucia or not?

He made landfall at Barbados and the Turks and Caicos. His eyewall grazed the island, but just a direct hit, no landfall.
