Floods kill 16 in Arkansas; dozens missing
Posted by: Dr. Jeff Masters, 4:24 PM GMT on June 11, 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.

Question for 456 or Drakoen,When you think is the timeframe for this to be tagged as a invest?


Invests tagging is subjective, so if I tell you it should be tagged a certain day then this is my thinking which independent of how the wave looks and what the NHC is thinking.

If the models continue to be consistent and we get some support from the EURO along with satellite presentations, then early next week. Otherwise, no invest 92L.

Quoting Weather456:


also I think it's relevant enough to the current wave in the current situation. if we want to connect this to seasonal activity then that will be something else...as for now, we are more concern whether the wave will develop or not.


True enough. The more development that occurs, the greater the moisture impact will be across the Windward and Leeward Islands.

Now I get it. I never use the /-. Only the ! when warranted.

Why anyone would read based on a filter based on the opinion of anonymous individuals is beyond me.

And, really, that should be the default setting.

In the year 2000, even though a tropical depression did form just off the coast of Africa toward the end of June, the first named storm did not form until August 3rd.

Of course, that would be the first of 15 storms to form that year, which is another example that confirms the notion that the season does not need to be active in June or July, in terms of named systems, to be an active season overall.


Yup.

I actually use the +/- option quite a bit.

I mostly use it to + people that are not trolling and for some reason are hidden from view when I am in not signed onto WU.

looking at the wv wave at 30 west does have alot of moisture to work with atm so it could have a chance to become 92l right ?

Most of the time I keep mine on show all and only "ignore" the trolls that aren't entertaining. Come the peek of the season and a couple storms popping I can crank it up pretty high. Cuts out a lot of background noise. I also make it my business to lurk as I know very little that is helpful to anyone else.

Thanks 456 and Drakoen for the answers to the invest question.

I want to say that discussions about different thinking of the tropics is enlighting and educational to those who dont know a lot about the theme of tropical waves / surface troughs that Levi and Drakoen did earlier.

Interesting tidbit. I noticed that some of the hurricane symbols on Kermit are "backwards". I'm assuming these are all storms flown in the southern hemisphere where they turn clockwise? Pretty neat.

Thanks for the insight.

Let's test it :)

A study: The temperature rise has caused the CO2 Increase, not the other way around


It works both ways. The fact that rising temperatures can create a massive release of CO2 from the oceans as it is less able to hold CO2 when warm presents a dangerous positive feedback. If global temperatures didn't warm after CO2 levels rose then this would defy the laws of physics which requires a balance in the net radiation budget that we learned about in the 18th century.

I agree that it is all about radiation for sure :)

I just keep thinking of those bugs and flowers found (DNA verified) at the bottom, in the mud, of the deep ice core samples from Greenland. Then again, the tree remnants on the northern shores of the same, create similar questions.
