Tropical Storm Allison was a weak but devastating tropical cyclone that struck southeast Texas in June 2001. It lasted unusually long for a June storm, remaining tropical and subtropical for 16 days, most of which was when the storm was over land dumping torrential rainfall. The storm developed from a tropical wave in the northern Gulf of Mexico on June 5, and struck the upper Texas coast shortly thereafter. It drifted northward through the state, turned back to the south, and re-entered the Gulf of Mexico. The storm continued to the east-northeast, made landfall on Louisiana, then moved across the southeast United States and Mid-Atlantic. Allison was the first storm since Tropical Storm Frances in 1998 to strike the northern Texas coastline. Tropical Storm: peak winds of 60 mph (50 knots), lowest pressure 1000 mb. June 5 – June 19, 2001. Landfalls: June 5 at 50 mph, 28.9°N 95.3°W; June 11 at 35 mph, 29.6°N 91.6°W. Accumulated cyclone energy: 0.6.
