At least 46 million people were under a winter storm warning as of Thursday as the storm spreads along the Gulf Coast Friday, according to the weather service. The storm should weaken by Saturday, bringing lighter snow between 1 and 3 inches to parts of the Northeast, the Mid-Atlantic and the Ohio Valley before exiting off the Carolinas.

The National Weather Service warned on Friday evening that a winter mix could still cause dangerous road conditions and an increased risk for power outages for parts of north Alabama.

The Triangle is likely to see snow and ice as part of a winter storm that is expected to reach the area Friday afternoon. A winter storm warning, issued by the National Weather Service in Raleigh, is in effect from 1 p.m. Friday to 10 a.m. Saturday.
