The National Weather Service has issued a winter storm warning in Delaware, effective 9 p.m., Sunday night through 4 p.m., Monday, March 3, for what is being characterized by NWS officials as the “most significant winter weather event of the season.” The forecast predicts snow accumulations of more than six inches, with the greatest amounts of 10-14 inches expected in central Delaware.
Precipitation is forecast to begin as rain tonight and convert to snow after midnight. Based on weather forecasts for tonight and tomorrow, it is likely the state of Delaware will issue a State of Emergency with a level 1 driving warning starting tonight.
DelDOT crews will be fully mobilized tonight and throughout the storm, with more than 450 pieces of equipment on the roads statewide.
DelDOT is urging residents to prepare for the storm by obtaining essential items, including medications, food and batteries, in advance of the expected precipitation.
Because the forecast is for snow to fall at a rate of as much as one to two inches per hour, it will be difficult for DelDOT plows to stay ahead of the accumulation on primary roads. For this reason, secondary and minor roads may not be attended to until the snowfall stops some time tomorrow.
With the storm likely to start as a rain event, it will not be effective to pretreat roads with brine today. Brine washes off roads when it rains.
