COLUMBUS, Ohio (AP) -- Ohioans awoke to below-zero temperatures again Tuesday and many schools throughout the state were closed a second day because of the dangerous cold.
Wind chills were expected to be a hazardous 30- to 40-below zero, which can cause frost bite on exposed skin within minutes. A wind chill warning remained in effect for the entire state.
University Hospitals in Cleveland said one person treated for hypothermia died there on Monday. The person's identity wasn't released. Authorities in northwestern Ohio said a 90-year-old woman died Monday after her car got stuck in the snow and she tried to walk home.
Authorities said Virginia McFeters was found in the snow outside of her retirement community in Wauseon, west of Toledo. They said her body was found about 150 feet from her car, which had gotten stuck in a drift. Neighbors say they don't know where she was trying to go.
Frigid weather hampered crews trying to repair a major water main break that flooded then iced some downtown Columbus streets, and made it more difficult for crews fighting a major fire that destroyed a historic restaurant in Waverly in southern Ohio.
Crews in Lorain County, west of Cleveland, worked overnight to restore natural gas service to about 2,200 customer affected by an outage, and recreation buildings in several cities were again opened as warming centers. Outreach efforts were underway to get homeless people out of the cold.
The coldest temperatures in Ohio in decades -- ushered in by a "polar vortex" affecting a large swath of the county -- also closed Ohio State University and caused the state Legislature to shuffle its schedule.
A warm up is expected after Tuesday. Highs are predicted to be in the 20s statewide on Wednesday, and they're forecast to rise to the 40s near the end of the week.
A sure sign the weather was improving: The Horseshoe Casino in Cleveland -- which had closed because of the weather Monday -- announced it would reopen at 4 p.m. Tuesday.
