Heavy downpours led to flash flooding across parts of the region Monday, some areas getting more than 3 inches of rain in less than an hour.
The storms washed out roads, leaving drivers stranded and emergency crews called in to rescue dozens of people. Roads turned to rivers and parking lots to lakes. Flash flooding hit parts of Maryland and the DC area of Monday morning, causing Amtrak to suspend train service.
Flood waters washed away Belfast Road in Potomac, a place where about 75 homes are located. The road is the only way to get to those homes, and officials say it could take weeks to fix.
In Frederick, the flood waters of Carroll Creek spilled over into Baker Park and emergency crews had to close as many as 15 streets, and more than a dozen vehicles became swamped.
City residents credited flood prevention improvements in recent years with turning the park into a virtual holding pond that kept homes from flooding.
