ATLANTA - Ice-slicked roads prompted warnings of treacherous driving conditions Thursday and delayed school openings across a swath of the country, mainly in the South.
In metro Atlanta and north Georgia, icy conditions prompted road closures a day after slick surfaces caused hundreds of car crashes in the area. Ice also covered streets as dawn broke Thursday in Louisville, Ky.
Schools in states including Georgia, Ohio, North Carolina and South Carolina either closed for the day or planned to open late.
In Ohio, plows were out in counties near the Ohio River. And a spokeswoman for Cincinnati/Northern Kentucky International Airport said airlines were experiencing weather delays and cancellations.
Workers were clearing snow to keep two primary runways open.
