Plows are clearing roads on parts of northern Arizona on the first day of spring after a storm dropped heavy snow that created traffic backups Thursday morning.
The Arizona Department of Transportation said roads across the region were snowy and icy Thursday morning and officials urged drivers to postpone travel.
The National Weather Service reported 12 inches of snow in Flagstaff at 5 a.m. and said light snow showers would continue through Thursday.
ADOT said Interstate 40 was open near Williams but that it'd take time to clear miles of traffic backup.
Isolated rain showers were forecast in south-central Arizona. A flood warning was issued for Tonto Creek in Gila County where flowing water closed unbridged crossings.
