Avalanche Advisory
Advisory: Ogden Area Mountains Issued by Evelyn Lees for Thursday - December 10, 2015 - 7:15am
bottom line

The avalanche danger is LOW this morning, but it could rise to MODERATE later today if the snow starts to drift where you are. Avoid any new wind drifts on slopes approaching 35 degrees or steeper. Overnight, the addition of new snow will continue to increase the avalanche danger to at least MODERATE, with slides potentially breaking into deeper layers.
current conditions

A cold Pacific storm is forecast to reach northern Utah by this evening. Ahead of it, temperatures are a bit cooler this morning – with most stations near or below freezing. The southwesterly winds are just starting to increase – into the 10 to 20 mph range, gusting in the 40s and 50s.

Snow coverage continues to be bleak – average depths are in the 8 to 16” range at the mid to upper elevations, with the pack unsupportable at times, so hitting rocks or logs is likely. Snow quality isn’t much better - the surface sports a combo of breakable wind and ice crusts until you get into shady, wind sheltered upper elevation terrain. A few inches to no snow at the lower elevations makes access hard to the upper elevation slopes.
recent activity

No new avalanches have been reported from the backcountry for the past few days, though cracking to the ground on facts was observed on the 8th on wind drifted, upper elevation slopes.

Snow available for transport is scarce, but the as winds speeds increase today or it starts to snow late this afternoon, some new sensitive drifts will form. Most of the drifts will be found in the upper elevation terrain, with some drifts well off the ridge lines and down in open bowls at slope break overs and around terrain features.

Days with increasing avalanche danger are tricky, so stay focused and as soon as you identify changing avalanche conditions – the new sensitive winds drifts – switch to wind sheltered terrain and lower angle slopes

description

Any triggered wind drift has the potential to break into the sugary weak snow lower in the pack, resulting in a deeper, wider slide. Again, while there is a LOW danger of slides this morning, stability will change fast once drifts start to form or it starts to snow. A slide breaking into a faceted layer will large enough to take you for a ride and especially dangerous to get caught in because you will be bouncing off rocks due to the shallow snowpack.

weather

A strong cold front will cross northern Utah around dusk today. Ahead of the front, we’ll have a last warm, blustery day, with 8,000’ temperatures rising into the mid 40s and 10,000’ temperatures into the mid 30s. The southwesterly winds will be ramping up by noon, peaking in the evening with speeds averaging near 30 and gusts in the 40s. Gusts across the high peaks may reach into the 80s. Snowfall should start around dusk, and 4 to 8” of snow are expected overnight. Temperatures will plummet into the teens, and winds shift to the northwest and decrease. The fast moving storm will be out of here by Friday morning, leaving behind a few lingering snow showers.
