The National Weather Service in Mount Holly has issued a * Flood Watch for portions of northern New Jersey and Pennsylvania, including the following areas, in northern New Jersey, Warren. In Pennsylvania, Monroe and Northampton. * Through Thursday afternoon * Flooding from ice jams is possible near and along the Delaware River below Bushkill. * Areas that are most susceptible to ice jam flooding include, but are not limited to Shawnee on Delaware, Smithfield Township Pennsylvania, and locations upstream to near Bushkill. River ice currently exists just downstream from Smithfield Township upstream to about Bushkill. The ice is mostly bank to bank and is causing restrictions. These restrictions can be seen at the Tocks Island USGS River Gauge. Although Tocks Island is measuring higher water, because there is ice present, exact water levels may not be representative. Keep in mind that flooding impacts that are normally seen with freshwater moving downstream can vary with water backing up. As the river ice fractures and releases, additional restrictions or ice jams could develop further downstream. PRECAUTIONARY/PREPAREDNESS ACTIONS... A Flood Watch means there is a potential for flooding based on current forecasts. You should monitor later forecasts and be alert for possible Flood Warnings. Those living in areas prone to flooding should be prepared to take action should flooding develop. && $$ Kruzdlo

The Flood Watch for portions of northern New Jersey and Pennsylvania has been cancelled. There remains considerable river ice along four miles of the Delaware River from the Smithfield Beach National Recreation Area downstream to the confluence of Brodhead Creek. However, colder air will be in place through mid week, temporarily limiting ice break up and minimizing the risk of ice jam flooding. By Thursday, a warm up could once again increase the potential for ice break up. We will continue to monitor this situation through the week. $$
