The severe weather poses significant risks to urban areas, including flash flooding that could disrupt commutes and inundate roads and subways. Damaging winds capable of knocking down trees are the primary threat, with tornadoes possible in regions like western New York and eastern Pennsylvania. Heavy rainfall rates of up to 2.5 inches per hour could exacerbate flooding, especially in areas already saturated from previous storms. The Mid-Atlantic states are particularly vulnerable to widespread impacts.
