Heavy rain swept across parts of the Northeast on Monday night, inundating sections of New York and New Jersey with flash flooding that stranded vehicles in roadways and closed subway lines.

New Yorkers in basement apartments were told to be ready to leave and New Jersey’s governor declared a state of emergency after heavy rains in the northeast caused flash flooding, officials said

Governor Phil Murphy declared a state of emergency Monday night as flash flooding across the northern section of New Jersey caused severe trouble. Murphy asked residents to stay indoors and avoid unnecessary travel. “I am declaring a State of Emergency given flash flooding and high levels of rainfall in parts of the state,” he said.
