FLAGSTAFF, Ariz. (AP) - A late winter storm dropped snow on parts of Arizona's high country Wednesday, slowing traffic and delaying school openings in Flagstaff.

Flagstaff had 8 inches of snow by 5 a.m. and forecasters said up to 3 inches of additional snow were expected by midday.

The Flagstaff Unified School District delayed schools openings by two hours due to the current and anticipated weather conditions.

The Arizona Department of Transportation reported slow travel on Interstates 17 and 40 in the Flagstaff area due to snow and wet pavement.

A winter weather advisory citing continued snowfall remained in effect until 11 a.m. for areas above 6,000 feet for a region stretching from the Grand Canyon on the north to Prescott on the south.
