Hello and good morning, this is Toby
Weed of the
We will continue to issue avalanche
statements intermittently through the month of April.
Current
Conditions:
Snowfall intensified dramatically in the
past few hours in the
Avalanche
Conditions:
Well, we finally got real a spring
snowstorm, and wind slab and storm snow avalanches are our main concern
today. The stability of the new
snow depends on the condition of the sun-crust it
falls upon. The theory is; if the
crust is frozen solidly when the snow starts to accumulate it won’t be as stable
as it will be if the crust is soft and warm. I’d recommend digging down to the
old/new interface to check the bond.
Wind drifting might cause a significant danger on lee slopes near
ridge-lines and around terrain features like gullies or rock out-croppings and
along vertical sub-ridges. New snow
instabilities (and powder snow quality) should only linger for a little while
after the storm abates, but loose wet avalanches will likely be an issue as
slopes are warmed by the inevitable spring heat.
Mountain
Weather:
We’ll
likely see a few more inches of snowfall in the mountains this morning, and snow
showers and clouds will persist through the day. A south wind will pick up overnight and
it will be mostly cloudy and mild on Friday in advance of the next Pacific storm
system. We’ll probably see more
snowfall over the weekend, but it looks like most of the storm energy will pass
to our south. More stormy weather
is on tap for next week.

backcountry observations to me at [email protected] or leave me a message

I will update this statement as
conditions change.
