Good morning, this is Evelyn Lees with the
In Provo Canyon, the county road and bikepath are closed from Bridalveil/Nunns parking lot to Frasier Park due to avalanche danger.
A colder, moist west to northwest flow kept snow falling, with the mountains picking up another 5 to 12 overnight. This brings upper elevation storm totals since Tuesday afternoon into the 1 ½ to 3 foot range, with 2 to 3 of water equivalent. The winds finally decreased, and are now 10 to 15 mph from the west northwest, with speeds across the highest peaks in the 20 to 30 mph range. Temperatures have cooled into the low 20s to upper teens at 10,000.
Natural avalanche activity from the backcountry yesterday consisted mostly of shallow new snow soft slabs, up to 100 wide, with wind loaded areas and north through east facing slopes the most active. Some slides initiated mid-slope due to wind loading well off the ridges. Ski cuts in the backcountry were easily releasing similar new snow slides, with results from control work at ski areas a bit larger, 1 to 3 deep and up to 400 wide. The largest natural reported was
While its winter up high, there are spring conditions at the lower elevations. There were both natural and easily triggered wet loose sluffs yesterday below about 8,000 that gouged down and resulted in impressive debris piles. If the clouds thin or the sun peeks out today, the snow may rapidly heat on many elevations and aspects, resulting in more widespread wet avalanche activity. Particularly avoid terrain traps such as gullies, where the cement like wet snow could pile up deeply.
(Salt Lake and Park City mountains)
The avalanche danger is CONSIDERABLE on slopes approaching 35 degrees in steepness with recent deposits of wind drifted snow, especially those shady slopes facing northwest through east. Other steep slopes have a MODERATE danger. There is a MODERATE danger of wet loose sluffs below about 8,000, and on any steep slope receiving direct sun today the danger may rise to CONSIDERABLE.
Bottom Line (
The avalanche danger is HIGH on and below slopes steeper than about 35 degrees. Both human triggered and natural avalanches are likely. Large natural avalanches have occurred overnight and this morning. People without good avalanche and backcountry travel skills should avoid travel in the
