Wider weather episode

A large thunderstorm complex moved east from the Ohio and Tennessee Valleys across southwest Virginia. The system caused dozens of trees to be toppled across the region. Heavy rainfall from these storms also caused localized flooding in the City of Roanoke, where rainfall rates were in excess of 4 inches per hour at one point, between a 5-year and 10-year rainfall event per NOAA Atlas 14 Point Frequency Estimates. Rainfall amounts across the City of Roanoke ranged from 1.50 to 1.75 inches, not unusual for thunderstorm activity, but still enough to cause localized flooding given the more urbanized nature of the impacted area.
