Another round of thunderstorms with very heavy rainfall moved through Allegany and Montgomery Counties during the afternoon of the 27th. In Allegany County, significant flooding occurred just east of Cumberland along the west slope of Martin Mountain after Elk Lick Run overflowed its banks. Flood waters damaged property in a 2.5 mile area along Baltimore Pike (Route 144) from Rocky Gap Road to Hinkle Road near Interstate 68. An apartment complex on Baltimore Pike was surrounded by flood waters. Twenty people had to be evacuated and were eventually displaced after 12 rental units sustained major flood damage. Twenty homes nearby were significantly damaged by flooding, including one which was moved off its foundation by the rushing water. An additional 50 to 75 homes sustained minor flood damage. Up to 15 private driveway bridges across Elk Lick Run were damaged and a parking lot was washed away. Three feet of creek water spilled onto Interstate 68 which forced officials to shut down the road for over an hour. Four to five inches of rain was believed to have fallen in this area in only 2 hours. In Montgomery County, dime sized hail fell in Germantown. Small creek flooding was reported in Damascus after 2.69 inches of rain fell. A few cars were stalled in high water on Clopper Road in Gaithersburg where 3.05 inches of rain was recorded. Water rushed through a home along Buck Lodge Road in Boyds. Several people were trapped in a pickup truck on West Old Baltimore Road when Ten Mile Creek overflowed in Clarksburg. Rushing water also left debris on several roads across the county.
