Baltimore tornado rips across harbor, damages warehouse [VIDEO] At least two tornadoes hit the Baltimore area on Monday as part of a severe weather system spreading up and down the east coast. According to the Baltimore Sun, one tornado tore the roof off of a warehouse as it ripped its way across the city's famous harbor. Witnesses watched the tornado -- also known as a spout when it crosses water -- tear part of the roof off a 300,000-square-foot warehouse in Locust Point. "I was about 80 feet up in the air and watched the whole thing from the beginning," a crane operator said. It looked farther away and then it made a turn toward us and that's when it took off that roof. "It looked like birds at first, but then I realized the way they were behaving did not look like birds," attorney Steve Fogleman said. It looked like sheets of vinyl siding. Local news reporters posted images of the tornado on social media:
