PHOTOS: Raging floodwaters rip through Ellicott City, Maryland
Rain and thunderstorms moved through the mid-Atlantic on Saturday with downpours leading to major flooding in some communities.
Baltimore was one of the hardest hit areas with radar-estimated rainfall of 4 inches just west of the city. Numerous water rescues were reported.
At least two people have been found dead in the aftermath of the flooding, according to WJZ-TV.
Roads turned to rivers in Ellicott City, Maryland, after 6.50 inches of rain fell in the area.
A report from the National Weather Service indicated that nearly 6 inches of rain fell in just two hours. Statistically, there is a less than 0.1 percent chance of that occurring in any given year in this area.
Maryland Gov. Larry Hogan declared a state of emergency in Howard County, home to Ellicott City, on Sunday.
"The thunderstorms caused extensive damage to property and infrastructure in the central part of [Maryland], including intense flooding in the historic town of Ellicott City," according to the Maryland Emergency Management Agency.
Flooding destroyed at least four structures and up to 30 sustained substantial damage. The majority of the damage was concentrated on Main Street.
Police towed more than 180 vehicles off the ravaged street and from the Patapsco River.
After the threat of additional storms later on Monday, conditions should stay primarily dry for the rest of the week, AccuWeather Meteorologist Joe Lundberg said.
"There will be some sunshine each day to aid in the drying and clean up," he said.
The deluge was not limited to the Baltimore area as flooding also occurred in New Jersey and Pennsylvania.
