Snow Emergency Levels in Miami County
Ohio law puts the declaration in the hands of each county sheriff, who may declare a snow emergency and temporarily close the state roads and municipal streets in the county when that is reasonably necessary to preserve the public peace. A level declared for Miami County applies to that county and stops at its line — the county next door can be at a different level, or at none. ORC § 311.07 and § 311.08
- Level 1 Advisory
- Roadways are hazardous. Motorists are urged to drive very cautiously.
- Level 2 Advisory
- Roadways are hazardous with blowing and/or drifting snow and possible icy conditions. Only those who feel it is necessary to drive should be out on the roadways. Employees should contact their employers with regards to questions about reporting to work.
- Level 3 Snow Emergency
- Road conditions are extremely poor and should only be utilized by emergency personnel. No one should be out during these conditions unless it is absolutely necessary to travel.
Quoted from the Miami County Sheriff, who declares them, at miamicountyohio.gov. That page is also where the level in force right now is posted; this one does not carry it. How snow emergency levels work across Ohio.
