In northern Arizona, Flagstaff Unified School District schools are closed Tuesday due to icy road conditions, while freezing conditions are forecast in parts of central and southern Arizona.

Freeze warnings will be in effect Wednesday morning in the Tucson area and southern Gila County, including Globe and Miami.
