Tropical Storm Agatha one of the top ten deadliest Eastern Pacific storms on record

The Eastern Pacific hurricane season of 2010 is off to a bad start. The mounting death toll from Central America's Tropical Storm Agatha has made that storm one of the top ten deadliest Eastern Pacific tropical cyclones on record. 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 at least 83 people in Guatemala, 13 in neighboring El Salvador, and one in Honduras. Guatemala is also suffering from the Pacaya volcano in Guatemala, which began erupting four 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.

Agatha is the deadliest flooding disaster in Guatemala since Hurricane Stan of 2005, which killed 1,513. In a bizarre coincidence, that storm also featured a major volcanic eruption at the same time, when El Salvador's Santa Ana volcano blew its top during the height of Stan's rains in in that country on October 1. The eruption killed two and injured dozens, and worsened the mud flow damage from Stan's rains. The deadliest Eastern Pacific tropical cyclone on record for Guatemala was Hurricane Paul of 1982, which made landfall in Guatemala as a tropical depression. Flooding from Paul's rains killed 620 people in Guatemala.

Rainfall amounts of 350 mm (14 inches, orange colors) were indicated for portions of Guatemala. The Guatemala government reported that rainfall exceeded 36 inches in some regions.

Oil spill update
Light onshore winds out of the south to southwest are expected to blow over the northern Gulf of Mexico all week, resulting increased threats of oil to the Alabama and Mississippi barrier islands, according to the latest trajectory forecasts from NOAA. These persistent southwesterly winds will likely bring oil very close to the Florida Panhandle by next weekend.

Some SST's! From discussion on TC 03a:

A buoy (23707) 85 nm south-southeast indicated slp near 1002.4 mb and SST exceeding 30c and a buoy (23708) 130 nm north-northwest indicated slp near 1002.6 mb and SST near 31c.

Ok, we have 91E. The NHC gives it a 10% chance over the next couple days... wait, they're naming invests that have a 10% chance? Awesome, more invests to track!


They always classified invests with that chance, it is just this year they are being more specific on the probability of formation

Last year it was yellow circle was less than 30%, now they are more specific

Don't think so... of course, I wasn't into the tropics at the time, I just probably thought it was rain.

Last thing I got was ex-Ida. It dumped a TON of rain. I'm on the Piedmont Plateau, and we flooded! We never flood here! A local school had a bunch of ceiling water damage.



Im on the eastern slopes of the Blue Ridge, about 1,300FT. Never thought Isabel would have brought sustained winds over 40mph here. Ivan closed schools here because of floods. Love the weather here, picked up 3 feet of snow last winter too.
