The U.S. National Weather Service in Mt. Holly, N.J., has issued a gale warning and wind chill advisory for the state of Delaware, due to the impending blast of Arctic weather expected beginning Monday afternoon.
The gale warning remains in effect through 6 p.m. Tuesday, while the wind chill advisory runs through noon Tuesday.
A gale warning means that winds will be shifting to the west and increasing in intensity to 20 to 30 knots, with gusts up to 40 knots (46 mph). Seas will range from three to five feet in height.
The combination of cold air and high winds also means the wind chill factor could reach between -10 and -15 degrees F.
In addition, those living on or near the water should be aware of a freezing spray advisory, which will be in effect until 6 p.m. Wednesday. The combination of high winds and cold air near bodies of water could result in light to moderate accumulations of ice on boats and ships.
Accuweather is predicting partly cloudy to clear skies beginning at 5 p.m., with temperatures dropping from 34 degrees (20 degrees wind chill) at 5 p.m. to 17 degrees (-4 degrees wind chill) by midnight.
Chances of precipitation remain less than 15 percent.
Temperatures will continue to drop through the night, reaching 6 degrees (-18 degrees wind chill) by 6 a.m. Tuesday, and rising only to 11 degrees (-10 degrees wind chill) by noon.
Temperatures will remain in the teens until at least 10 a.m. Wednesday, and will not reach freezing, 32 degrees, until approximately 11 a.m. Thursday.
Roadways will become treacherous as a result of rain and melting weekend snow that will freeze over.
DelDOT spokesman Jim Westhoff said primary and secondary roads in Kent County will be treated with salt and local roads also will be treated, with attention paid to intersections and known problem areas. DelDOT crews will continue to inspect roads and will treat them as needed, Westhoff said.
