Heavy Rain and Possible Flash Flooding in the Northeast and Northern Mid-Atlantic
A strong cold front will push through the Eastern U.S. today with strong thunderstorms, heavy rain and possible flooding. The main zone for these hazards will be from portions of the Mid-Atlantic into parts of the Northeast, as a tremendous amount of moisture interacts with the cold front. This includes a portion of the I-95 corridor from Baltimore to Philadelphia and New York City.
