Logan area Avalanche statement

Thursday April 12, 2007

Hello and good morning, this is Toby Weed of the Forest Service Utah Avalanche Center with your Logan Area backcountry avalanche and mountain weather advisory.  It’s Thursday April 12th and it’s 7:00 in the morning.  This advisory is brought to you in part by the Friends of the Utah Avalanche Center in Logan with help from Simmons Flexi-ski of Providence.

Due to lack of snow in the backcountry we’ve discontinued our regular advisories for the season. We will continue to issue avalanche statements intermittently through the month of April.

Current Conditions:

 Yesterday, we were surprised to find widespread deposits of brownish wind-blown snow.  The top inch or so of Tuesday’s fresh accumulation is significantly darkened by the wind-borne dust, and you could feel the snow rapidly collect heat in the sun.  The strong westerly winds blasted nearly all the new snow from exposed slopes and deposited a uniformly thick, frosting-like layer in lee terrain.   Upper elevation slopes picked up a few inches of nice snow, and you might still be able to find good but dusty dust-on-crust conditions in sheltered shady terrain.  With the brown dust in the upper layer, sunny slopes became slow and sticky quickly in yesterday’s sun, and I expect you’ll find crusts this morning and more sloppy and sticky snow by afternoon.  Mountain temperatures should stay in the mid-thirties today and drop into the low twenties overnight.

Avalanche Conditions:

Yesterday, we found solid cornices and stubborn drifts in the 1’-deep range.  Wind deposited snow appeared fairly well welded into place and we were unable to trigger even small wind slabs on very steep slopes.   The remaining old snow is well refrozen thanks to recent cold temperatures and any avalanche problems today will be limited to new snow.  But, with the darkish dust embedded in the snow surface absorbing heat more rapidly than normal, you’ll be able to trigger loose wet avalanches that may become significant on long slopes.

 Bottom Line:

We are no longer issuing danger ratings.  Avalanches are generally unlikely this morning, but loose wet avalanches will become more possible in the midday and afternoon heat on steep slopes in the backcountry. 

 Mountain Weather:

Snow showers are possible today, but little accumulation is expected as the storm passes mainly to our south.  Friday and Saturday should be fair with seasonally normal temperatures, (below freezing at night and highs in the low 40s during the day).  The next storm enters the region on Saturday night and we’ll see a good chance for more snow in the mountains Sunday and Monday.

General Information:

Check out photos of avalanches in the Logan Area on our images page.

Go to the Avalanche Encyclopedia if you have any questions about terms I use in the advisory.  I also recommend the recently-released Media Page, which shows the forecast danger for our coverage areas across the state.

Please continue to e-mail backcountry observations to me at [email protected] or leave me a message at 755-3638.  I will frequently check my messages throughout the spring.

I will update this statement as conditions change.
