New Jersey is under a state of emergency after a flash flood caused at least two deaths in Plainfield and damage across Union County.

Two people died when flash floods struck New Jersey on Monday, submerging cars, flooding roadways and canceling flights. The victims were killed when their car was swept into Cedar Brook in Plainfield, city officials said. This comes days after two others were killed in severe storms in Plainfield on July 3.

A state of emergency was declared in New Jersey after slow-moving thunderstorms unloaded a significant amount of rain, resulting in dangerous flash flooding across the Northeast into Monday night. At least 2 were killed.
