Good morning, this is Drew Hardesty with the
With warm air streaming in ahead of tonight’s storm, overnight lows are in the upper twenties and low thirties, about 10 degrees warmer than the night before. The winds picked up yesterday out of the south and southwest blowing in the 20’s and have increased to 25 mph out of the southeast. Cloud cover will build through the day with light rain/snow falling by mid-morning.
Recent Avalanche Activity & Snowpack Discussion:
We have two avalanche problems in the
snowpack right now, those that I refer to as “manageable”, and those that go by
many other names, but we’ll just call them “unmanageable”. The localized sensitive soft
photo) from yesterday’s southerly winds fall under the manageable category,
where they are pretty predictable and break just at your skis or board. The few that were triggered yesterday were
just off the ridgelines or below a steep rollover in exposed terrain. Now for the unmanageable
slides. Two parties remotely
triggered two avalanches yesterday, one in mid Little Cottonwood canyon and the
other along the
Winds will continue to whip the snow into sensitive soft slabs today over a wider expanse of terrain. With more of a load now on the buried weak layers, remotely triggered avalanches may be more prevalent in upper elevation shady terrain.
Areas of CONSIDERABLE danger exist on some mid and upper elevation steep slope with recent deposits of wind drifted snow. While they may be most prevalent along the upper elevation northwest through northeast facing slopes, terrain channeling can load any aspect. Human triggered slides are probable with a few naturals possible in the steepest upper elevation terrain. Sheltered terrain unaffected by the wind will have a LOW danger today.
The next Pacific storm is racing in from the west and we’ll initially see light rain up to about 8000’, with the rain/snow line dropping slowly throughout the day. The southerly winds will continue to the tune of 25-30mph along the high ridgelines, before dropping off after the front moves through overnight. 10,000’ temps will drop to the low twenties tonight. Favored locations should pick up a foot of snow with light snowfall continuing intermittently Tuesday and Wednesday ahead of a colder, more potent storm on Thursday.
Here is a great link to a web site on avalanche beacon information, created by a person who did independent research and testing of avalanche beacons. http://beaconreviews.com/transceivers/index.htm
There are several free automated avalanche beacon practice areas open, including one at Canyons, one on the by-pass road near Snowbird and one in the northwest corner of the lower lot at Solitude. They are really easy to use, and well worth stopping for a quick practice session.
Early birds and snow geeks can catch our 6AM report at 364-1591.
