A quick-hitting storm that dropped up to a foot and a half of new snow on the Wasatch Mountains by Monday (Feb. 9) afternoon prompted the Utah Avalanche Center to issue an Avalanche Warning for backcountry users.
"This vigorous storm has produced one and a half feet of snow since this morning in many areas of the Wasatch Mountains," Avalanche Center Director Bruce Tremper wrote Monday afternoon. "Natural avalanches are occurring on many steep slopes. An avalanche warning has been issued for the Wasatch Mountains from the Utah-Idaho border to Mt. Nebo."
Tremper added that while the Provo and Ogden area mountains received a foot of snow early Monday morning, the Salt Lake area mountains only had a few inches, but since Monday morning snowfall in the Salt Lake area mountains piled up another 18 inches within just a few hours during the day. The Center anticipated another eight to 10 inches of snow to fall overnight into Tuesday morning as the next wave of this storm was expected to hit Monday evening.
Avalanche conditions are rated as "High" on all aspects above 10,000 feet, and "Considerable" on all aspects above 8,000 feet.
