Avalanche advisory

Monday, January 10, 2005

 

Good morning, this is Drew Hardesty with the Forest Service Utah Avalanche Center with your backcountry avalanche and mountain weather advisory. Today is Monday, January 10, 2005, and its 7:30 in the morning.

 

UDOT WILL DO CONTROL WORK IN PROVO CANYON BY 10 AM AND WILL BE CLOSED TO ICE CLIMBING. UDOT IN THE COTTONWOODS HAS A NEW ROAD CLOSURE HOTLINE: 975-4838.

 

Current Conditions:

Overnight the central Wasatch picked up another 4-6 of graupel and dense snow and its still snowing. Since Friday night, storm totals are 20-30 and nearly 5 of water. The winds have let up slightly from the west southwest as most anemometers are reading 15-20 mph with more exposed anemometers still humming along at 30mph, gusting to 40. Temps continue their 48 hour upward march and are near 30 at 10,000. Rain snow lines seem to have been fluctuating between 7000 and 8000.

 

Avalanche Conditions:

No new avalanches were reported from the backcountry yesterday, although I suspect more folks were watching football or working on taxes. More reports of naturals from Saturday are trickling in and Ill have our avalanche list updated by 10am.

 

The snow and water amounts keep adding up and I think we may be at the breaking point soon in areas that have received and continue to receive the most, such as the Cottonwoods, Park City mountains, and the Provo mountains. The new slabs are still best described as stubborn, but I feel with continued heavy dense snow and moderate to strong winds, some areas will reach a critical threshold and well start to see natural activity. At least on the mid and upper elevation northwest through east facing slopes, it will be possible for any avalanche to step down to the buried weak layers from November or December.

 

With rain snow lines hovering around 8000 or so, wet sluff activity is likely at the lower elevations and ice climbing should be avoided for at least another day or so.

 

Bottom Line:

The current avalanche danger is CONSIDERABLE and may rise to HIGH today on and below any steep slope at the mid and upper elevations. Natural avalanches will be possible today and any slide triggered will have the potential to be large and extremely dangerous.

 

Bottom Line for the Provo Mountains: As the Provo mountains appear to have picked up another 2-3 of water weight in the last 24 hours,the danger on mid and upper elevation steep slopes is HIGH. Avoid being on and under steep slopes.

 

Mountain Weather:

Snowfall should continue throughout the day with 6-8 of snow expected. Winds should continue from the west southwest averaging 20-25mph. 8000 highs will be in the mid-thirties 10,000 temps in the upper twenties.
