BOONE — Urban and small-stream flooding is possible in poor-drainage areas until 11:45 p.m., according to the National Weather Service in Blacksburg, Va.
“A line of slow moving thunderstorms was tracking across Watauga County," the advisory stated. "This will likely result in flooding of low-lying, poor drainage and normally flood prone areas, including such locations as the Boone Mall parking lot and roadways."
Some locations that will experience flooding include Boone, Blowing Rock, Beech Mountain, Foscoe and Sugar Grove.
"In hilly terrain there are hundreds of low water crossings which are potentially dangerous in heavy rain," the advisory stated. "Do not attempt to cross flooded roads. Find an alternate route."
