Extreme flooding caused major damage Sunday in Ellicott City, Maryland, washing away vehicles and even some buildings less than 24 months after another catastrophic flood struck the town.

In the wake of the floods, one man was found dead. Eddison Hermond, 39, was reportedly assisting with water rescues when he was swept away. Hermond was an active member of the Army National Guard, officials said.

The city faces its second major flooding crisis in just two years. Many had just finished recovering and rebuilding from the previous disaster in 2016.

According to weather.com meteorologist Jonathan Belles, a line of stagnant thunderstorms dropped more than 6 inches of water in just under two hours between Ellicott City and Baltimore. Some spots may have received 10 inches of rain in a three-hour span. The Patapsco River, located southeast of Ellicott City, experienced a 17-foot-climb in water levels over those two hours.
