Remnants of Tropical Storm Allison


The 2001 Hurricane Season had barely been proclaimed on June 1, when Tropical Storm Allison formed in the western Gulf. While Allison was never strong enough reach hurricane force and weakened to below tropical storm strength early in its life, the low pressure center that remained after Allison menaced residents from Houston to New Orleans with catastrophic flooding. The storm remained parked over eastern Texas for several days, then moved eastward along the Gulf Coast, bringing welcome relief to residents of eastern Texas and southern Louisiana. However, this movement brought flooding and severe weather to Mobile and Pensacola and inland counties on June 11.

The rainbands brought an average of around 5-7 inches to some areas. Although the coastal counties of Alabama and northwest Florida Panhandle had been suffering from a moderate drought in previous few weeks, the heavy rains caused some localized flooding.

Allison brought damaging winds to much of the area, including at least 2 weak tornadoes. Most damage occurred in George County in MS and across Mobile and Covington Counties in AL.
