Western Caribbean disturbance moving over the Yucatan
Posted by: Dr. Jeff Masters, 02:01 PM GMT on Οκτώβριος 04, 2008 +1
Heavy thunderstorm activity in association with a broad area of low pressure over the Western Caribbean remains disorganized today. Visible satellite loops show a modest area of heavy thunderstorms, with no sign of organization or a surface circulation. This morning's QuikSCAT pass showed no signs of a surface circulation, either. Wind shear is moderate, in the 10-15 knot range.

The disturbance is drifting westward, and should move over northern Guatemala, Belize, and Mexico's Yucatan Peninsula today before it can develop into a tropical depression. These areas can expect heavy rains of 2-4 inches today through Sunday from the disturbance. NHC is currently giving it a low (<20% chance) of developing into a tropical depression.

Elsewhere in the tropics, the NOGAPS model is forecasting the possible formation of a tropical depression off the coast of Nicaragua on Thursday, while the GFS model thinks something might develop off the coast of Africa Thursday. It's a little late to be getting an African storms developing, so I doubt the GFS forecast. However, we'll need to watch the Western Caribbean over the coming week.

Hurricane Ike relief efforts
When a major hurricane hits, relief efforts are always confused and don't reach many areas with great needs. Thus, a group of wunderground bloggers mobilized the day after Ike hit to help out. Their goal was to provide immediate help where traditional aid efforts were coming short, with a focus on providing equipment for people with disabilities and a full spectrum of relief supplies to smaller communities often neglected. Traditional, professional relief efforts are weighed down by bureaucracy and cannot respond as nimbly as smaller, grass-roots relief efforts can. I believe our dollars have been well-spent by the relief effort organized by our own Patrap, Presslord, and Stormjunkie, under the banner of Portlight Strategies, Inc. I encourage you to donate to the cause, or the traditional charity organization of your choice.

Here's a breakdown of how much money has been donated, and how much spent. Figures are rounded to the nearest $100. More details can be found on StormJunkie's blog:

Total money donated: $31,200 (about 400 donors)
Total money spent so far: $10,350
Total money in the portlight.org checking account: $21,000
--$9,000 in escrow for legal defense
--$12,000 available for immediate relief operations
Total money in the original Paypal account set up by Patrap: $1000
Total money in the new Paypal account set up by Presslord: $250

Here's how the $10350 has been spent:

WalMart - $2000 - supplies
Costco - $1000 - supplies
Patrick Pearson (Patrap) - $1000 (fuel, rental costs for a truck)
Truck from Charleston - $1500 - fuel
Florida supply truck - $2100 - escort, credentialing, fuel, vehicle repair, lodging
Crew food,lodging, transport home - $1000
Truck rental, gas for truck from Atlanta - $1750

The biggest coup for the effort came when portlight arranged to get about $150,000 worth of medical equipment donated to the cause. Rob Ingham (AKA Rainman32) and Roger Knight (AKA NLimbo) took a rented truck to Atlanta, grabbed the gear, and delivered it to Houston. In the shipment:

Four Gaylord boxes medical supplies
-Soft casts
-various catheter kits
-catheter bags
-oxygen tubing kits
-other misc. medical supplies
13 hospital bed mattresses and pressure pads
2 Gaylord boxes of sanitized walkers (20 per box)
4 Gaylord boxes of unsanitized walkers (20 per box)
2 pallets with two electric wheelchairs each (4)
100 pairs of crutches
30 bedside commodes sanitized
6 gerry chairs

Quoting cchsweatherman:

thanks cchs, I raised the query earlier as I did not see anything on noaa or ecmwf, no ciculation is also bad for the islands as that area of activity will dump lots of rains...suppose heavy rains, flooding.. is not really activity........

Quoting Vortex95:
The GFS model shows a developing TS moving in the middle of the atlantic and a Strong high pressure system that could keep it on a more westerly track for a while.
