Will Ice Jam Cause Flash Flooding on the Delaware?
A massive, one-mile-long ice jam near Trenton is clogging up the Delaware River, meaning communities along the river should watch out for flash flooding. (Coast Guard ice-breakers are currently breaking ice to try to prevent this.)
The [flood] watch covers Philadelphia, lower Bucks County, northwest Burlington County and Mercer County, and is now in effect through 10 p.m. today, the National Weather Service said this morning.
And a flood warning is in place through 4 a.m. Friday for parts of Bucks and Mercer counties near the jam. The weather service said the river at Trenton was at 19.9 feet this morning, just below the flood stage of 20 feet.
Meanwhile, in Easton, that’s exactly what’s happened along the Lehigh River, which experienced a similar ice-jam.
