The snow started in the Illinois Quad-Cities shortly before 11 a.m., and a blizzard warning is in effect for the area until midnight, according to the National Weather Service Quad Cities.
The snow is expected to be heavy and wet and continue through late afternoon, with a total accumulation of four to eight inches, according to the NWS' winter warning online at crh.noaa.gov/dvn/.
Many minor accidents have been reported. Because of the initial warm pavement temperatures, roads may become icy, according to the NWS.
Heavy snow and high winds could reduce visibility to zero at times, and travel in rural areas could become very dangerous, the NWS states.
Winds are picking up and were expected to be 30 to 40 mph by mid-morning. Gusts up to 55 mph are possible from late morning through the afternoon. Winds are expected to be about 30 to 35 mph through late evening, according to the NWS.
Temperatures will fall into the 20s and wind chills will drop it into the single digits this evening.
The NWS encourages people to stay home. If an emergency requires driving, the NWS recommends taking a winter survival kit and staying with your vehicle until help arrives if you become stranded.
