The river level was just over 18 feet on Tuesday morning. Flood stage is at 20 feet.
Officials say that minor flooding is expected along several roads, including Route 29 in Trenton.
Authorities say that drivers should be cautious and not drive through flooded areas.
The flood warning expires at 1:00 p.m. EST on Tuesday.
