Tropical Storm Agatha, Pacaya volcano kill 15 in Guatemala; oil spill update
Posted by: Dr. Jeff Masters, 2:39 PM GMT en Mayo 30, 2010 +2
Tropical Storm Agatha, the first Eastern Pacific named storm of 2010, was short lived but deadly. Agatha was a tropical storm for just 12 hours, making landfall Saturday on the Pacific coast of Guatemala as a 45 mph tropical storm. However, the storm brought huge amounts of moisture inland that continue to be wrung out as heavy rains by the high mountains of Guatemala and the surrounding nations of Central America. So far, flooding and landslides have killed twelve people in Guatemala, and one person in neighboring El Salvador. According to the excellent Guatemala weather site, climaya.com, rainfall amounts of up to 152 mm (six inches) in 24 hours have occurred in some regions of Guatemala. The National Hurricane Center is warning that rainfall amounts of up to 30 inches may fall the next few days in some mountainous regions near where the storm has dissipated. Adding to the mayhem is fallout from the Pacaya volcano in Guatemala, which began erupting three days ago. At least three people have been killed by the volcano, located about 25 miles south of the capital, Guatemala City. The volcano has destroyed 800 homes with lava and brought moderate ash falls to the capital.

Oil spill update
Light onshore winds out of the south are expected to blow over the northern Gulf of Mexico today through Tuesday, resulting increased threats of oil to the Alabama and Mississippi barrier islands, according to the latest trajectory forecasts from NOAA. Winds are expected to shift to southwesterly on Wednesday and continue through Friday, increasing in force to 10 - 20 knots late in the week as a cold front approaches the Gulf. These persistent and strengthening southwesterly winds will likely bring oil very close to shore from Mississippi to the Florida Panhandle by next weekend.

Join the "Hurricane Haven" with Dr. Jeff Masters: a new Internet radio show
Beginning next week, I'll be experimenting with a live 1-hour Internet radio show called "Hurricane Haven." The show will be aired at 4pm EDT on Tuesdays, with the first show June 1. Listeners will be able to call in and ask questions. Some topics I'll cover on the first show:

1) What's going on in the tropics right now
2) Preview of the coming hurricane season
3) How a hurricane might affect the oil spill
4) How the oil spill might affect a hurricane
5) New advancements in hurricane science presented at this month's AMS Conference on Hurricanes and Tropical Meteorology
6) Haiti's vulnerability to a hurricane this season

I hope you can tune in to the broadcast, which will be at http://www.wunderground.com/wxradio/wubroadcast.h tml. If not, the show will be recorded and stored as a podcast.

I'll probably be back Monday with a quick update. Have a great holiday weekend!

I'm positive it lost it's low level circulation, the mid/upper level circulation might still be there. If you look on satellite animation it looks as if it's moving towards the Caribbean, this could also be the attributed to the thunderstorms diminishing.

Any chnace it could redevelop in the Caribbean?

Remember 2005? The season started on June 8th and there was a total of 28 named storms. Although one might think that because it's going to be a "hyperactive" season doesn't mean it has to start early, heck even I expected it to start early, but I was wrong.

If ex-Agatha can make it to the Caribbean, which I doubt it will do, and still maintains a mid/upper level circulation it shouldn't have any problem developing a lower level circulation. We'll see...

The mid/upper level circulation is moving ENE/E towards more land.. what I'm watching is the low at the surface, sure the core may have fallen apart, but there is still a broad spin moving towards the NNE.. I think a low will reform near the yucatan tonight/tomorrow

I don't want to be unable to access this blog if something really dangerous is approaching. Even though one should always listen to their local media for information, it is nice to know this blog is still here to pass messages, etc.

Nice Post, Dr. Masters.

If a severe hurricane makes landfall this year, there will be FEMA money for immediate relief.... but communities shouldn't expect much federal help rebuilding this time.

FEMA has already run out of their official budget and available supplies this year due to the number of disasters.

The earthquake in Haiti, snowstorms in the North-East and the flooding in Tennessee have FEMA seeing red. They have about $1 Billion in projects outstanding due to past disasters including Katrina rebuilding efforts that they don't have adequate funding for.

FEMA this year has said they will be able to provide immediate relief for a disaster, but probably won't be able to help with the rebuilding or long-term costs. During an election year, FEMA can get an emergency spending budget approved to assist. We can't expect a vote to cover funding for long-term rebuilding or relocation assistance this time, unlike 2005.

For 3-years after Katrina, evacuees were receiving relocation benefits in Houston. We all know about the FEMA trailers, the evacuation reimbursement checks and of course all of the federal housing and rebuilding assistance in New Orleans. 2005 may have been the pinnacle of federal help for a disaster.

This year will be different. Funding will be available for short term relief, but not for long term. The shrimpers, fishers and oyster-men on the Gulf Coast can't expect much FEMA help for the oil spill damage. Likewise, communities damaged by a severe hurricane can expect political visits, national guard troops handing out water and MRE rations... but don't expect a lot more help after the storm than that.

That was my point -- 2010 may not eclipse 2005 because it will ahve at least a normal start. I would be REALLY worried if it started out early...

Anything that can stay below 20˚N of longitude has a decent chance of surviving. I've been hearing a lot of questions about Ex-Agatha surviving in the BOC, and the answer is no. Ex-Agatha can not survive in the BOC and this is why:

I believe that would depend on how far south the dust would be. There was plenty of SAL during 2005 but, if I remember, it was farther to the North and did not affect the storms which formed closer to the ITZ. Anyone have info on what the SAL was during 2005?
