Severe winter weather affects all parts of Ohio. A winter storm occurs when precipitation (snow or sleet) forms at cold temperatures or when the ground temperature is cold enough where ice forms (freezing rain). Accumulations of snow and ice often make conditions hazardous to motorists and pedestrians. Ice storms and heavy snow fall may cause power and telecommunication outages, disrupting activities for days. While Ohio residents and governments are accustomed to handling winter storm events, occasional extreme events can make conditions dangerous and disruptive.
