Flash floods are the number one weather disaster in the U.S. and are common in Maryland. Flooding after a storm (sometimes long afterward) can cause flash flooding of streams, marshes and other low-lying areas, even in densely populated areas. If you get caught in a flash flood, don’t drive or walk through the water - get to higher ground. Learn more about flash flooding at the National Weather Service website.
