Little change to Caribbean disturbance 94L
Posted by: Dr. Jeff Masters, 2:54 PM GMT en Noviembre 15, 2010 +3
An area of disturbed weather (Invest 94L) in the southern Caribbean between Colombia and Nicaragua has seen a modest increase in thunderstorm activity this morning, but is battling dry air, and the odds are against the system becoming Tropical Storm Virginie. Satellite images show that 94L has a limited amount of heavy thunderstorms, but the activity is increasing, and a low-level circulation is getting better defined. Water vapor satellite images show a large amount of dry air lies to the north over the northern Caribbean, and this dry air is slowing development. 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. Morning 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, for the next five days. The modest shear and warm SSTs may allow for some slow organization of 94L over the next few days, if the storm can wall off the dry air at mid-levels that has been interfering with development. The models predict that the steering currents in the southern Caribbean will keep 94L moving generally west-northwestward at about 5 - 10 mph for the next three days, which would bring the storm ashore over Nicaragua or northeast Honduras on Wednesday. The models are not showing much development of 94L, and NHC is giving the system just a 20% chance of developing into a tropical depression by Wednesday. I'd put the odds higher, at 30%. The Hurricane Hunter mission into 94L scheduled for today has been canceled, but is slated to go on Tuesday afternoon. At this time, it appears that 94L will stay confined to the Caribbean, and will not be drawn northwards across Cuba towards Florida and the Bahamas.

I'll have an update Tuesday.

Summary

Westerly winds of 60 to 80 km/h will develop over southern sections of Greater Victoria, the Southern Gulf Islands and metro Vancouver tonight. Northwest winds up to 90 km/h will develop over west coast Vancouver Island this evening. This is a warning that potentially damaging winds are expected or occurring in these regions. Monitor weather conditions..Listen for updated statements.

Details

A deepening low pressure system is forecast to move from the north coast this evening and track across the southern interior tonight. In the wake of the low strong northwest winds reaching 90 km/h are expected over west coast Vancouver Island this evening and westerlies of 60 to 80 km/h are forecast to develop over Victoria, the Southern Gulf Islands and Vancouver tonight. Winds will abate early Tuesday morning as the low exits the interior.

well any way this is what they said in our forcast last bit

OUTLOOK:(An increase in cloudiness and shower activity from Wednesday morning as cloudiness associated with a broad area of low pressure system over the southwest Caribbean drifts west to northwest) this is important anyway I am going to work tomorrow so by then we should have an idea of what's going on

18W & 98S are gone.. Model performance on 94L is very similar to Tomas. CMC is out preforming with 21nm error. Was a little farther off yesterday. GFS ~72, has shown some skill (if we throw out yesterday). I still think Belize might bear the brunt. Roatan should see some rain from it too. HWRF is doing well so far on intensity (current 8kt error in the last 24hrs), it's leaning for a fairly weak storm.

Not getting popups on other sites I go to. One time I got 14 pop up pages when opening a blog here.

Not sure if the extra features are worth 10 bucks or not, to be honest.


I have adblockplus already. I'll try the spywareblaster.

A nasty bit of rogue software "Windows Security Essentials 2011" has been making the rounds in my circle. It's one of those fake programs that turns off your security software and flashes fake security alerts on your computer. Malwarebytes was the only security software I have that took care of it.
Even if you don't run it, I think it is good to update your security software daily. And if you get that rogue software, run the malwarebytes immediately.


I got this one. If you have windows, restart your computer in basic mode (F8 when booting), then go to start\user\whatever you are\AppData\local\temp\ and then eliminate the *.exe that starts with numbers. Then run your security software to get the rest of the files.

I think 94L will not make it to TD status. Conditions are only marginally favorable and convection is almost all gone. Pressures have risen in that region as well. I believe the 2010 season has come to an end imo.

Whether or not it forms into a TS, a lot of rain will fall and can be just as destructive.

The Mosquito Coast will be full of newly hatched ones very soon.

I have a reason for why the NHC kept 94L at 20% is because the T storm and showers have increased over the center although minimal and it is also organising it self slowly

well sorry IKE I thought that is what you intended when you posted that
