Tropical Storm Allison [SEP] Impact
Tropical Storm Allison was a major flood disaster throughout its path from Texas to the Mid-Atlantic. The worst of the flooding occurred in Houston, Texas, where over 35 inches (890 mm) of rain fell. Allison caused approximately $8.5 billion in damage (2001 USD), making it the costliest tropical cyclone that was never a major hurricane on record in the Atlantic basin. The storm also killed 41 people directly, including 27 who drowned. This ties Allison with a tropical storm in 1917 as the second-deadliest tropical storm to affect the contiguous United States, surpassed only by the 1925 Florida tropical storm which killed 73 people.
