Floods kill 16 in Arkansas; dozens missing
Posted by: Dr. Jeff Masters, 4:24 PM GMT op 11 juni 2010 +2
Heavy rains in excess of seven inches fell over southwestern Arkansas overnight, triggering flash floods that killed at least sixteen people in Caddo Gap, in the rugged Ouachita Mountains. Forty people are missing, with dozens injured. The closest weather station to the disaster is Mount Ida, which recorded 7.16" of rain over the past 48 hours. The USGS is reporting that the Caddo River in Caddo Gap rose from 8.4 feet at 3am CDT to 25.39 feet in just five hours, reaching the 2nd highest flood height on the river since records began in 1989. The Little Missouri River west of Caddo Gap rose 20 feet overnight, from 3 feet to 23.5 feet. The previous highest flood in the 22-year record at this location was just 14.66 feet, set in 2008. You can look at local rainfall amounts and river flood levels in the region using our wundermap with the "USGS River" layer turned on.

Andy Revkin at the New York Times has a blog worth reading on the disaster.


Figure 1. Radar estimated rainfall for June 9 - 11 over Southwest Arkansas. Rainfall amounts in excess of eight inches are indicated for Caddo Gap, where today's flood disaster occurred.

Oil spill update
Southeast to south winds of 10 - 15 knots will blow today through Saturday, according to the latest marine forecast from NOAA. These winds will keep oil near the shores of Louisiana, Alabama, Mississippi, and the extreme western Florida Panhandle, according to the latest trajectory forecasts from NOAA and the State of Louisiana. The winds become light an variable Sunday through Tuesday, which will result in little movement of the spill. The long range 8 - 16 day forecast from the GFS model indicates a continued regime of light winds, mostly out of the south or southeast. This wind regime will likely push oil onto sections of the eastern Louisiana coast during the period 1 - 2 weeks from now.

Quoting atmoaggie:

Okay, so if BP wasn't around in it's current form, who pays for the fix and cleanup next week, next year, and a decade from now when litigation gets somewhere?

Go ahead, destroy BP and then the magical, unseen, infinitely wealthy taxpayers can foot all the bills.

Yes, BP needs to pay. Criminal offenses considered and charged, if warranted, but we actually need that corporation to live on, for now.


You are exactly right. I hate what happened, but rather than boycott, I filled up at BP for these reasons: 1) I need gas. 2) They need to remain in business to pay claims. 3) A govt $11T in debt doesn't need another $100B added to the total.

You know, if you take the total US debt balance and divided by the number of people that file tax returns, we all owe about $150K each just to break even.

The best analog storm I can find for this AOI is Hurricane Florence of 2006, which developed off a ITCZ wave and followed a similar track to what the CMC is predicting.

Florence as a wave:

Actually I read 456's blog and this ITCZ disturbance should make it to the Bahamas, there this should be watched big time. You have low shear and warm SSTs.

Yea based on satellite imagery and ascat...i would assume it's the next best thing to a closed circulation (if it isn't closed already)






Based on the recent ASCAT and satellite imagery, the circulation is elongated west to east.

Quoting JFLORIDA:
BP, Transocean workers argued before blast: witness

Brown said "a skirmish" took place between "the company man" from BP -- whose name he said he did not know -- and three Transocean employees.

"The company man was basically saying,
'Well this is how it's going to be,'" and Transocean rig workers "reluctantly agreed," Brown said.

The argument concerned "displacing the riser," Brown said, a reference to a decision made by rig personnel to remove heavy drilling mud from the drill pipe and replace it with water, in an attempt to wrap up drilling operations and plug the well with cement.

I dont see how anyone can defend BP with a straight face.


Mr. Brown is an employee of Transocean, a company that could be held liable. Mr. Brown may also be a "company man" just with the other company. Let the investigations run the course. The important thing right now is the clean up.

Anticyclonic outflow aloft...those red barbs represent cloud motion between 100mb and 400 mb, the upper levels. No yellow barbs in the vicinity of the wave which would show low level cloud motion. These are obscured by thunderstorms.

Unbelievable.

DO you actually think they wont trying a reorganization or bankruptcy to minimize liability even after paying out dividends.

Keep trusting them - its worked so well to this point.

Do you know how much economic hardship this is going to cause?

Utterly unbelievable and irresponsible.


knowing our government, even if they go under, there will probably be a bail out waiting for them

Any storm that passes through the Bahamas region or Gulf of Mexico should rapidly intensify, if upper level winds are favorable, of course.

30C SSTs do not guarantee development nor rapid intensification. All they do is provide the potential for both of those things, by providing more upward motion and heat supply to sustain thunderstorms which can aid in development. However, at this time of year, wind shear is a big moderating factor, and no matter how hot the SSTs are, a TUTT or subtropical jet will easily kill a disturbance.

FWIW, they are cooperating much better voluntarily paying right now (w/o waiting for judgements) than the Mexicans ever did for Ixtoc. Pemex declared sovereign immunity because they were a foreign company, and avoided paying even a dime in US claims and clean up costs. If Obama continues to be a grand standing idiot, BP could be inclined to pull same stunt based on precedence.

Claudette is an example of a tropical wave that eventually made it to the GOM and developed, Katrina is a tropical wave that eventually made it to the Bahamas.

Quoting JFLORIDA:


Who said anything about not getting every dollar out of their carcasses to cover this spill.

They have been paying out dividends - as the gulf literally dies.

BP directors will meet on Monday to discuss whether to suspend dividends to shareholders, the BBC has learned.

Executives will then meet with US President Barack Obama on Wednesday, but no announcement on the payments is expected in the near future.


THere are many ways to go after those in charge such as prosecution and going after their individual assets by suing them PERSONALLY without the scorched earth method. Many average Americans own shares of BP stock either as an individual holding or in mutual funds.

Would you feel this way if your retired grandmother living on a fixed income was counting on the dividend on her 100 shares? The corporate bigwigs will be fine without the dividend. It is the little people who won't be.

I know I may sound like a BP schill, but I AM NOT. I am just concerned with the unintended consequences of what could happen to regualr people. The middle class is hurting right now and hurting everyday Americans doesn't solve anything.
