HOUSTON (AP) — Hurricane Harvey slammed into Texas last August as a powerful Category 4 storm, killing dozens of people and causing billions of dollars in damage.

Its fiercest winds quickly dissipated, but Harvey hovered for days as it trudged inland, dumping several feet of rain on many Gulf Coast communities and the Houston area.

A National Hurricane Center report says Harvey killed 68 people, making it the deadliest U.S. storm since Superstorm Sandy in 2012.

Federal statistics show all but three of the Harvey deaths were directly attributed to freshwater flooding, which damaged more than 300,000 structures and caused an estimated $125 billion in damage. Adjusting for inflation, Harvey was the second costliest tropical cyclone in U.S. history, trailing only Hurricane Katrina in 2005.
