2. Our Current Status NY, PA & NJ Since the recent precipitation has been in freezing or frozen form over most of Pennsylvania, New Jersey, and New York, little change has been experienced with the river ice. Precipitation tonight and tomorrow should again be mainly freezing or frozen. Without a significant amount of liquid runoff, there is no force to break up the thick river ice and get it moving. We expect ice to remain in the rivers through the week.

3. Our Current Status MD, VA & WV Panhandle For much of Maryland, the West Virginia panhandle, northern Virginia and the higher elevations of central Virginia, we've noticed ice effects diminishing. The river ice has been eroding for several days now. We expect that trend to continue. Flows are high and that, along with the additional rain and "milder" temperatures should be enough to push ice out. Any ice jams that do happen to form should be isolated.

4. Important Monitor http://water.weather.gov for updates As always, please stay alert, monitor http://water.weather.gov, and share river ice observations with your local NWS office. River ice is very difficult to predict and conditions can change rapidly. Ice jams can cause quick rises, and even flooding.

5. Recent River Ice Photos & News Thank you to everyone who continues to share your photos of the river ice with us. We are sharing these photos, plus any news we gather, through our Facebook and Twitter accounts, everyday. Following MARFC on Facebook & Twitter is the best way to stay up to date on the river ice because, as you know, conditions can change rapidly.
