June 1, 2012 Flash Flooding

The intense thunderstorms that caused tornadoes and wind damage across portions of the area Friday afternoon and evening also contained very heavy rainfall rates. As thunderstorms trained repeatedly over the same locations of the Washington and Baltimore metropolitan areas and north-central Maryland, rainfall amounts of 2 to 4 inches were common, in as little as one hour. Numerous creeks and streams flooded out of their banks, forcing road closures. Several high water rescues were performed and the National Weather Service has obtained several dozen reports of Flash Flooding. Floodwaters gradually subsided Friday night as rain ended. Below is some photos of the flash flooding.
