What the reports say
Written by National Weather Service staff at the time of the event · public domain
Heavy thunderstorm rains produced over 3 inches of rainfall at several locations across Garrett County. This heavy rain forced creeks out of their banks in the Gorman area, forcing the temporary closure of several roads. Motorists were stranded in several feet of water in both Gorman and Pleasant Valley, and a few needed to be rescued from their cars by local fire companies. Several reports of flooded basements were also received in the Oakland and Gorman areas.
Only hours after one round of thunderstorms dropped up to 2 inches of rain across the county, another round of strong thunderstorms passed over the area and produced widespread flash flooding problems. Just north of the Friendsville area, a campground was evacuated due to flooding from Mill Run Creek. More than 20 county roads, mostly in the northern portion of the county, were either damaged or temporarily closed due to flooding. In addition, flooding forced the temporary closure of State Route 42 in the Friendsville area and State Route 135 in Bloomington.
Strong, slow-moving thunderstorms produced torrential rainfall of up to 3 inches in just over an hour over portions of Garrett County. In the Keysers Ridge area, minor road flooding was reported on SR 40. Mudslides were also reported along Interstate 68, where nearly half a foot of water and debris covered the roadway. Several other roads in the county reported flooding, including Devils Half Acre Road, which was partially washed away. In the Grantsville area, Mill Camp Road was also flooded.
