Winter Storm Gandolf caused several accidents and slideoffs throughout Summit County Thursday afternoon and evening.

While Summit County Sgt. Ron Bridge said there were no county road accidents or storm-related incidents, Summit County deputies did assist the Utah Highway Patrol with numerous accidents and slideoffs within the county.

Utah Highway Patrol Corp. Todd Johnson said there were six accidents and 16 slideoffs on state highways throughout Summit County between 4 p.m. and midnight. However, there were no reported injuries.

The Park City Police Department reported the Mine Road was also closed during the afternoon rush hour.

As of noon Friday, Summit County snowfall numbers had not yet been reported, but Heber reported receiving 7.5 inches, Deer Creek Reservoir 4 inches and Morgan 1.7 inches, according to the National Weather Service.

A winter storm warning for heavy snow and strong winds is in effect in the area until 6 p.m. Saturday, with anticipated snow accumulations of one to two feet.

Northwest winds are expected to create blowing and drifting snow, particularly through mountain passes and higher terrain.
