The Severe Weather Outbreak of May 2nd-3rd, 2009

The period between the afternoon of Saturday, May 2nd 2009 through Sunday morning of May 3rd marked another major weather event for the four-state region. Some locations across the region experienced severe thunderstorm activity and tornadoes, while other locations received up to 6 inches of rain. And a few locations saw it all.

The National Weather Service in Shreveport is still in the process of fact-gathering as no part of the forecast region was spared from intense thunderstorm activity, which is unusual for such a large area. Storm surveys will be conducted across portions of northeast Texas, southwest Arkansas, and north central Louisiana over the next few days to document as many occurances of storm damage as possible. However, here is a quick look of the information we have already gathered:

Wind Damage:
Media and Emergency management reporting that the town of Dodson LA in Winn Parish was completely destroyed. Widespread wind damage is being reported from the early Sunday morning Derecho from Lufkin in Angelina County across Sabine and Shelby County Texas through Sabine, Red River, Natchitoches, Winn (where Dodson is located), Grant, LaSalle, and Ouachita Parishes in LA. Widespread power outages and trees down on homes are being reported across the region. In Northeast Texas, several lines of storms moved across northeast Texas late Saturday evening causing widespread tree and power line damages. Several tornado warnings were also issued. Several injuries were reported across this region from falling trees and power lines. The NWS will conduct a survey all across the region Sunday and Monday to assess damages.


Flooding:
Numerous homes and cars have been reported flooded across the Arkatex. Late Saturday night across east Texas, several counties (Bowie, Camp, Cass, Wood, Gilmer, Upshur, Titus, Franklin, and Red River) reported numerous road closures in each of the counties. In Texarkana, several cars were flooded out in intersections with several underpasses flooded. Early Sunday morning, numerous road closures were reported in Shreveport. Several CoCoRAHs sites have reported up to 6 inches of rain within a few hours. Some homes have also reported water on the south side of the city.
