In Baltimore City, the fire department said damage to the Amazon warehouse involved a section of an outer wall measuring about 50 feet by 50 feet that collapsed. He adds that a second person was unaccounted for. "The safety of our employees and contractors is our top priority and at this time the building remains closed", Rachel Lighty, a company spokeswoman, told the Sun. "Our thoughts go out to all families impacted by this evening's severe weather". No other injuries were reported by Amazon.
The National Weather Service is surveying the area to determine whether a tornado touched down.
The tornado briefly lifted before touching down again at an apartment complex in Dundalk.
The Baltimore Sun reports that it was the first fatal tornado - described as a "low-level EF-1 tornado with winds up to 105 miles per hour - to hit Maryland since 2002".
