Avalanche Advisory
Advisory: Ogden Area Mountains Issued by Mark Staples for Thursday - March 31, 2016 - 7:32am
bottom line

This morning the avalanche danger will be mostly LOW except at higher elevations on slopes loaded by today's increased NW winds where the danger is MODERATE. Additionally, the wet snow avalanche danger should rise to MODERATE this afternoon if some sunshine gets through this morning's cloudy skies.




current conditions

A trace of snow may have fallen this morning. Temperatures are in the low 30's F at 8000 feet and in the mid 20's F at 9000 feet. Winds have increased since yesterday and are blowing about 10-15 mph from the NW with gusts of 20 mph. The sun appeared enough during the last two days to warm the snow surface and form a crust this morning on southerly aspects and low elevations.

recent activity

Following Monday's storm there were many avalanches on Tuesday. These dry snow avalanches were breaking within the new snow. Yesterday the new snow had settled and become much less senistive to sliding. However, one surprinsing avalanche was intentionally triggered in the Mill Creek drainage of SLC near Gobblers Knob in Depth Hoar bowl. This slide reportedly broke 16 inches deep and 200 feet wide. We have few details on it.

Cloud cover and cool air temperatures prevented most wet snow avalanches yesterday. High temperatures yesterday reached the low to mid 30's F below 8000 feet and the snow became wet but not unstable.

Yesterday my partners and I skied a NW aspect on Gobblers Knob where the new snow was well bonded to the ice crust underneath it. We got one small piece of snow to move about 10 feet downhill on the crust. This snow wasn't much wider than a ski length and was mainly a sign of instabilities from Tuesday. I was surprised to hear about the slide in nearby Depth Hoar bowl. Overall however, the new snow has stabilized since Monday's storm. Avalanches may occur on slopes not affected by the wind in isolated places, but they will be more likely on slopes loaded by increased NW winds today.

Cloud cover and cool temperatures should limit wet snow avalanches today. BUT, the sun is strong enough this time of year that it doesn't need much time to heat the upper foot of snow and cause loose wet snow avalanches. A skier near Snowbasin easily triggered loose, wet snow slides on Tuesday when skies cleared and temperatures quickly warmed. If skies remain cloudy and air temperatures remain cool, there shouldn't be any wet snow avalanches. The best chance for warming and some sunshine should be this afternoon.

weather

Snow is falling this morning and another inch or two may accumulate today. Skies should remain cloudy for most of the day and high temperatures at 9000 feet should reach the upper 20's F. At 7000 feet temperatures should reach the low 40's F. Winds will continue from the NW and blow 20 mph at ridgetops.
