Avalanche Advisory

Advisory: Ogden Area Mountains	Issued by Bruce Tremper for March 28, 2013 - 6:52am

Above 8,500 ft.

7,000-8,500 ft.

Below 7,000 ft.

bottom line

The avalanche danger will rise from Low this morning to Moderate this afternoon.

Watch for:
1) Wet sluffs and perhaps some glide avalanches with afternoon heating
2) With afternoon convective showers, watch for recent wind slabs deposited in upper elevation dry, loose snow and also for small avalanches in the graupel (that Styrafoam ball-type of snow)

danger scale:	1. Low	2. Moderate	3. Considerable	4. High	5. Extreme

Daily field observations from a small army of volunteer observers as well as the UAC staff.
Road conditions including avalanche closures and webcams
Critical mountain weather information including current conditions, forecasts, satellite loops, radar, and mountain weather cams
Emergency contacts for a fast rescue response and your GPS location.
Ability to take a photo watermarked with GPS location, steepness, aspect, elevation, time and date

Thanks to generous funding by Backcountry.com and to Jonathan Lund and our other friends at Garafa for their hard work and generous support for the Utah backcountry community.

Also, be sure to take our quick survey on a different view for the avalanche danger rose:

current conditions

Temperatures continue their slow uphill trend. It was in the lower 50's in the mountains yesterday and only freezing overnight. Most slopes have a sun crust with the exception of some lingering dry snow on the upper elevation northerly facing slopes that still ride pretty well. Check the Snow Page for details.

The 3-day temperature and relative humidity graph

recent activity

No significant activity reported yesterday except for a few wet sluffs on steep slopes as they heated up. More glide cracks are appearing as well. But then again, not many people were in the backcountry yesterday.

description

Tricky, changeable weather today will create tricky, changeable avalanche conditions. It will really feel like spring today with very warm temperatures combined with afternoon convective clouds, which may produce graupel and even some lightning. So you will have to watch for a variety of different avalanche concerns today based on what the weather does:

1) Watch for wet sluffs and perhaps some glide avalanches with afternoon heating
2) Convective afternoon showers often produce strong, gusty wind, graupel and perhaps even lightning. So watch for wind recent wind slabs deposited in upper elevation dry, loose snow and also for small avalanches in the graupel (that Styrafoam ball-type of snow that stings your face).

Generally the avalanche danger from these problems will be relatively minor with the overall danger rating rising from Low this morning rising to Moderate by afternoon.

weather

As my soon-to-be-96-year-old, Czech Mother in Law says, "Spring is a fight between winter and summer." Today's weather will have more choices than a Chinese restaurant. Take your pick, warm, sun, clouds, rain, snow, wind, perhaps even some lightning. If you don't like it, wait 5 minutes.

Temperatures should rise from freezing this morning to the mid 50's again and then we should get some convective, afternoon showers that could bring--who knows what?

The extended forecast calls for more of the same spring weather for as far out as we can see.

If you trigger an avalanche in the backcountry - especially if you are adjacent to a ski area – please call the following teams to alert them to the slide and whether anyone is missing or not. Rescue teams can be exposed to significant hazard when responding to avalanches, and do not want to do so when unneeded. Thanks.
