A month's worth of rain fell in the DMV in less than two hours Monday

Three to six inches of rain fell Monday morning, washing away roads and bringing down trees

WASHINGTON — July's average rainfall fell in less than two hours Monday morning. We received nearly 10 percent of our yearly average precipitation in less than two hours. It is not possible for a winter atmosphere to hold the amount of moisture that today's atmosphere held, but for perspective sake, our morning rainfall would have been three and half feet of snow.

Last May, Ellicott City received six to nine inches of rain over a six hour period. And in some ways, our Monday deluge was just as impressive. Ellicott City's topography makes flooding more frequent and dangerous.
