The East Coast will be plagued with severe thunderstorms Wednesday evening that could lead to tornadoes, according to the National Weather Service. Damaging wind gusts and large hailstones are possible in the eastern states. 

Tornado watches have been issued until 11 p.m. EST for Washington, D.C., Philadelphia and Baltimore. Parts of New Jersey, Virginia and North Carolina also have watches in effect. The tornadoes are expected to be isolated, but intense. "Scattered severe storms with tornadoes, a few of which should be strong, and damaging winds are expected across parts of the Mid-Atlantic States into the Carolinas this afternoon and evening," the National Weather Service Storm Prediction Center said in a statement.



The thunderstorms may reach as far north as New England on Wednesday evening. Many areas will experience extreme flooding. In New Jersey and Washington, D.C., flash-flood warnings were issued until 10:15 p.m. EST and 11 p.m. EST, respectively.



In some East Coast states, people had already taken to social media to share their storm, flood and tornado photos and videos.
