Flash flood warning in effect for Princeton region until early Sunday

The National Weather Service in Mount Holly has issued a flash flood warning for northeastern Mercer County, southeastern Somerset County, Middlesex County, and Monmouth County until 2:45 a.m. on Sunday.

More than an inch of rain has fallen already, and another inch of rain is possible in some areas. The ground was already saturated from the rain in recent days. Flash flooding is expected to begin soon or has already begun in some areas in the Central New Jersey region. Flooding of small creeks and streams, urban areas, highways, streets, and underpasses as well as other low-lying areas is possible.

Turn around, don’t drown when encountering flooded roads. Most flood deaths occur in vehicles. It is harder to recognize the dangers of flooding at night. Stay home if you can. Turn around if a road is flooded, and do not ignore road barricades.
