Mountain temperatures are in the 20’s and winds are from the south and southwest and strong, with gusts in the 30’s and 40’s mph above about 9500’, and gusting in the 60’s mph at 11,000'
Overnight snowfall totals in the Provo-area mountains are 6”.
For today’s weather, you can expect mountain temperatures in the 20’s with 4-6” additional snowfall. Winds will be from the southwest and west, gusting in the 20’s and 30’s above 9000’, with even stronger gusts at 11,000’
There were no reports of avalanches in the Provo mountains on Saturday, but just a bit to the north, 8 human-triggered avalanches reported from the Salt Lake backcountry on Saturday.
These were all hard wind slabs, 6” to 24” thick and 25’ to 200’ wide. Some ran up to 350’ vertical. In 4 of the slides, at least one member of the party went for a ride, with injuries involved in 2 of the occurrences. These hard wind slabs were on slopes facing north, northeast, and east, aspects what we refer to as leeward
as they were drifted from the windward
south, southwest, and westerly winds. However, one slide was on a west aspect, indicating how terrain can channel winds and deposit fresh drifts on almost any aspect. These slides were all in large, open, exposed terrain, and generally above 9500', although one very close call on Blue Ice in Broads Fork (observation
) was at 9000'.
