afternoon, this is
I must say, Iím very impressed.† This is
the best October snow cover in the 19 years Iíve been in
Today, the main problem was soft wind slabs, mostly along the ridges breaking 4-8 inches deep and 20-40 feet wide.† Avalanche control in upper Little Cottonwood Canyon produced more widespread avalanches around 11,000í breaking about a foot deep. These wind slabs are very sensitive, especially when they sit on an old sun or wind crust from yesterday.† Although most of them are quite soft, they are harder, deeper and more dangerous along the highest ridges and in some other wind exposed areas.† Clues to instability will include cracking of the new snow.† As always, you should avoid any steep slope with recent wind deposits.† Check them out before you commit yourself.
A second avalanche problem today was damp and wet snow below about 9,500í. There was some rollerballs and surface sluffing at lower elevations.† Damp to wet surface sluffs could trap you in a terrain trap such as a gully.
Remember, for the most part, the unopened ski areas are not doing control work, and are just as dangerous as the backcountry.† †Alta Ski Area will be open to uphill traffic on Friday and possibly Saturday but may close for uphill traffic again depending on Saturdayís forecasted storm.
avalanche danger is MODERATE
on slopes steeper than about 35 degrees with recent deposits of wind drifted
snow, which are most widespread along the higher ridgelines.† The avalanche danger is also MODERATE on steep slopes below about 9,000í which are
getting damp to wet.† Elsewhere, the
danger is generally LOW.† The rest of this storm looks like it wonít
put down significantly more snow overnight but if we do get more than about a
foot of new snow or if the winds pick up, the avalanche danger will rise.† Places like the south slope of the
We might see another 4-6 inches of snow overnight with ridgetop winds staying moderate from the west and turning northwest by morning.† Overnight temperatures will drop to the mid 20ís and the daytime high on Friday should be around the mid 30ís at 8,000í.†† We have a bit of a break in the weather on Friday with partly cloudy skies and some light snow showers.† Then , a colder storm comes in from the northwest on Saturday night, which should give us perhaps another foot of snow.
If you are getting out, drop us a line or an email with any reports or observations from the backcountry.† You can leave us a message at 524-5304 or 1 800-662-4140.† Email us at [email protected], or a fax to 524-6301.†
