The National Weather Service has issued a flood warning for nine southern and central New Jersey counties, warning that the night's heavy rainfall could cause rivers and small streams to overflow. 

Burlington, Camden, Gloucester, Atlantic, Cape May, Salem, Cumberland, Monmouth, and Ocean counties are included in the flood warning, set to expire at 4:15 a.m. Thursday. 

“Given the already saturated conditions from precipitation earlier today, these bands will produce runoff sufficient enough for small streams to exceed their banks,” the warning reads. “In addition, rainfall rates will produce urban and poor drainage flooding in the heavier rain bands.”

A flood warning means the National Weather Service predicts flooding is imminent or has been reported.

The National Weather Service offered advice on flooding:

“Be especially cautious at night when it is harder to recognize the dangers of flooding. If flooding is observed, act quickly. Move up to higher ground to escape floodwaters. Do not stay in areas subject to flooding when water begins rising.”
