The city of Royal Oak has declared a snow emergency effective at 4:45 a.m. Wednesday.
The winter weather advisory extends into the morning, according to the National Weather Service. The snow is expected to lighten up early and temperatures will hover just above freezing, which means the snow that does accumulate will be heavy and wet.
According to the city, "snow emergency conditions are generally defined as a snowfall of four inches or more and will remain in effect until your street has been plowed." City officials said all vehicles parked on residential streets are to be removed or will be towed. It takes about 24-36 hours to plow all city streets, depending on how much snow has fallen.
