BALTIMORE (WUSA9/WJZ/AP) -- A massive storm system is making its way across Maryland, bringing huge hail, heavy rain, and strong winds.
The National Weather Service issued flash flood and severe thunderstorm watches and warnings for much of the region.
In Rising Sun, Cecil County, an 18-year-old female employee of the Plumpton Park Zoo was struck by lightning. She was out on the grounds working at the zoo when the storms rolled through around 9:10 a.m.
The victim was transported to a local hospital. No other injuries have been reported.
In Westminster, a 380-year-old White Oak came toppling down after being struck by an apparent burst of heavy wind.
The tree hit a car when it landed, barely missing a house that is about 50 feet away.
Officials are reporting trees down, roads closed and tens of thousands of power outages across Maryland and Delaware after a line of heavy thunderstorms moved through.
Carroll County Emergency Management Director James Weed says large hail fell near the communities of Union Bridge and New Windsor west of Westminster Thursday morning. He says it piled up "to the point that it looked like snow on the ground."
Baltimore Gas and Electric reports about 8,300 customers without power, mostly in Carroll and Baltimore counties. Potomac Edison reports another 4,600 customers without power in Carroll, Frederick and Allegany counties.
The damage comes from a complex of storms that left tens of thousands without power in the Midwest.
