Severe weather and heavy rainfall are possible in the Princeton region Wednesday afternoon and evening.
A flash flood watch is in effect until 2 a.m. Thursday, Sept. 9, for Mercer, Somerset, Hunterdon, Middlesex, Warren, and Sussex counties in New Jersey and Bucks County in Pennsylvania.
Thunderstorms with heavy rain are expected to move through the region Wednesday evening. The ground is already saturated due to the heavy rain last week. Additional heavy rainfall of one to two inches is possible in a short period of time, and could quickly lead to flooding in areas that are flood-prone and other low-lying areas.
Isolated tornadoes are possible Wednesday evening over Southeastern Pennsylvania and New Jersey north of Interstate 95. Localized flash flooding is possible in Southeastern Pennsylvania and Northern New Jersey. Damaging winds are also possible.
Police are recommending that residents check storm drains on their streets and clear them if the drains are covered in debris.
Don’t drive through flooded waters. Turn around. Stay home if you can.
