Monday, January 15, 2018, 17:49 - The U.S. National Weather Service issued a flood warning along parts of the Delaware River  through late Monday (January 15) saying that an ice jam could cause minor flooding.

At  4:00 p.m. EST Monday the Delaware River at Trenton was 19.8 feet. The flood stage is 20 feet, according to the agency.

The local NBC news affiliate said the warning covers parts of Pennsylvania and New Jersey which straddle either side of the river.

It said the ice jam had already flooded some roads along the river and that the weather service cautioned drivers not to drive through flooded areas because the water may be deeper than they think. 

“It is some pretty impressive icing,” police Capt. Robert Lewis said Monday morning in an interview with the Bucks County Courier Times. “Right now it is pretty stable and the ice continues to flow south. But it is unpredictable at this point as to what exactly is going happen.”

Ice jams to the lower end of the river, where floating chunks of ice pile up on each other during a January thaw or spring melt, and the river flow slowing to a crawl, often turn localized flooding into an extreme situation.



The Delaware River Basin, which spans five states, is a vital water source for more than 15 million people.

The river is forecast to fluctuate near flood stage through Tuesday. As of 7 p.m. EST, 20 U.S. streamguages were reporting water levels above the National Weather Service defined flood stage. A state of emergency has been declared for parts of New England (see videos below).

Over the weekend, flooding due to broken ice jam led to the evacuation of more than 20 homes in Fort Covington, New York.
