TRENTON, NJ (MERCER)–Winter weather has officially settled into New Jersey, and with the weather comes opportunities for winter fun. However, full layers of ice have not been able to form due to fluctuations in temperatures. That means ponds, rivers and lakes may not be as frozen as they look and are dangerous for ice skating, ice fishing and snowmobiling. Ice thickness, particularly in lower elevations and coastal areas, can be inconsistent and often unsafe. The best way to stay safe is by paying attention to warning signs and to STAY OFF THE ICE!
