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.

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.

Diamond blade, and they don't have to worry about heat. Just hope they don't get it stuck or bound up if the pipe sags on it. BTW, wonder how hard it is to change the blade…


Stuck would be interesting to say the least. (Another robot to cut from the other side...) Changing the blade is probably not that difficult. Pull it up, change the blade, drop it back down. Might take some time for the 1 mile journey each way.

Howver, I bet they are not using your typical Home Depot diamond blade either...

Storm Opens Giant Sinkhole in Guatemala

AOL News (June 1) -- It looks like a gateway to hell. A 200-foot-deep sinkhole in the north of Guatemala City suddenly opened up in the aftermath of Tropical Storm Agatha, pulling a three-story building and a residential home into the bowels of the earth.

The colossal chasm is just the latest sign of the chaos caused by this weekend's wild and violent weather, which killed at least 145 people across Central America. Agatha dumped more than three feet of rain on Guatemala and El Salvador over the weekend, causing rivers to burst their banks and hills to collapse into floods of slurry. The sinkhole, a nearly perfect circular shaft wider than a street intersection, appeared soon after the storm stopped lashing the capital.

Hey there! I asked in an earlier blog about the snake in your avatar - what type is it?

aspectre "Will you guys jut CUT IT OUT? At least think for a minute. [...]"

1995 SiestaCpl "Please understand that the question is out there, not that i endorse it. I have been working in the mining industry internationally for 28 years and I do know well the need for cost recovery and I have witnessed poor decision making based on the cash recovery need. Patrap's comments clarified and dismissed the subject excellently. No vitirol is needed in posts here."

My apologies. I hadn't seen Patrap's response, nor your acquiescence to his answer.

My overly impolitic introductory sentence came from the fact that I do have STRONG feelings that things are BAD enough without (essentially) adding a criminal conspiracy by BP to deliberately prevent the catastrophe from being stopped.
And that things are complicated enough without introducing conspiracy rumors (and politics) into (darn near every) serious discussion about what is occurring.

Reminds me of people finding certain trolling comments on this blog to be highly distasteful... then reposting the comments in full. If ya don't like it, at least don't make the rest of us have to scroll through it again.
So basicly, you wrongly got the brunt of my displeasure with those who insist on echoing trolls, when by this forum rules, they shouldn't even be acknowledging trollish statements.

Once again, I extend my apologies.

Not sure when the A-B high will finnally "set" for the peak of the season but current ridging continues in the vicinity of Bermuda......That will be a major factor in the tracks come the CV portion of the season and we will have to see whether these storms will have a tendancy to plow through the Lesser Antilles in the the Caribbean, or, take a more Northen jog towards the Greater Antilles/North Caribbean on the way towards Florida and the Gulf......The anticipation for this potentially very active season is quite nerveracking......Not looking forward to August and September but all we can do really is to prepare and hope for the best for your particular location.....

The real deal will likely start around the July 4th holiday, as the next strong MJO upward motion pulse will be arriving near the end of June/early July.

No followup explanation necessary. BP regularly suspends drilling in each well individually to cement in the latest casement.

nice shot. i didn't see that, bust must have been on the south end of the massive rainstorm that rolled through Okaloosa county around 8:30


It was. I'm sure this is a common occurrence here in Destin but I had to take a pic. Sometimes I will see these waterspouts when I go fishing back in Louisiana but usually I don't have a camera on me. Believe it or not it briefly touched the water about a minute later but by the time I got my cam out it was dissipating.

I would think the GOM would be much colder due to the cold winter you guys had, that's why many places got snow, Moisture from the GOM cause of no storms in 2009 hurricane season. Which mean's they had a bit of catching up to do, but they have well and truly caught up now.


The gulf surface water is affected by winds and cold northerly fronts dropping through, but latent heat is stored in the deep layers of the gulf that are reached only by the stirring of large tropical systems. This latent heat when, not dissipated, allows a quick rebound of SST's as we have seen this season.

In other news...(from the 8 a.m. NHC Discussion)
TROPICAL WAVE IS ALONG 78W S OF 12N MOVING W 10-15 KT. WAVE IS OVER THE SW CARIBBEAN AND MOVING INTO THE E PACIFIC REGION.
SCATTERED STRONG CONVECTION IS WITHIN1 75/90 NM ALONG THE COAST OF COLOMBIA AND W PANAMA BETWEEN 73W-78W.
Looking at shear, vorticity, upper and lower level divergence/convergence, seems to be a lot going on in that area right now. Would love to hear the technical analyses.


Yeah I've been keeping an eye on that. The front-running wave mentioned in the discussion is starting to interact with a newly-reformed monsoon trough, which just now got reestablished near Panama after being severely disrupted last week. This interaction is causing low-mid level rotation just south of Panama. Because of this most of the action should stay Pacific-side, but the NOGAPS has been consistently bringing the next wave, currently over Venezuela, north of Panama and dragging a low into the southern Caribbean where it strengthens it. Not sure how much I buy into this yet, but I'll be watching it.

It's also worth noting that even if the NOGAPS is correct, such a low would move WNW into central America, not north towards anywhere else.

Diamond blade, and they don't have to worry about heat. Just hope they don't get it stuck or bound up if the pipe sags on it. BTW, wonder how hard it is to change the blade…

Good morning all

Today we have Ex Agatha round two underway. Yesterday the small low drifted to the North and got sheared out.

Today, a slightly different scenario so far. While there are similarities to yesterday, such as a relatively small surface low, no signs of rapid organization and high surface pressures in the general vicinity there is one noticeable difference between the two and that is that today that low is just sitting in one place avoiding the shear to the North.

While 1012 mb is relatively high it wouldn't take much for that to drop a couple of mb by late this evening if it maintains itself.

Overall, the convective pattern is superior to yesterday's attempt and for these reasons this one is more worth watching IMO than the low we saw in the same area on Monday.
