Little Cottonwood Canyon Circuit

The biggest issue here is the missing avalanche bulletin. The Utah Avalanche Center has suspended their rating for the Salt Lake zone — typical for late April when the season winds down — but that doesn't mean the mountain is safe. It means the professional eyes are off it. The discussion note to 'watch for recent avalanches, cracking, and audible collapsing' is their way of saying: you're on your own, use field observations. With snow showers in the forecast every day through Saturday night and temps hitting the low-to-mid 40s°F at canyon level, wet loose avalanche activity on sun-exposed aspects is a genuine afternoon hazard. Plan to be off steep terrain by noon or 1 PM on any day with sunshine.

The weather pattern is active but not extreme. Today is the ugliest window — 34°F with snow showers likely at 69% precip probability, winds 10 mph WNW. That's light loading on any new storm slab problem, but without a bulletin you won't know if there's a buried weak layer underneath. Friday and Saturday are similar: temps reach 44°F, chance of snow showers, and Saturday night ramps back up to 83% precip probability with snow showers. The WNW and NW wind direction through Friday will load east and northeast-facing terrain. SSW winds Saturday and Saturday night will flip loading to north and northeast aspects. Watch for wind slab development on those lee aspects whenever you're above treeline.

SNOTEL data in the vicinity shows 52 inches depth in the briefing summary, but the three listed stations — Annie Springs, Long Lake, and McNeil Canyon — are California Central Coast gauges and have nothing to do with Little Cottonwood Canyon. Disregard those readings entirely. For LCC-relevant snowpack data, check Collins (8,000 ft) or Snowbird (9,840 ft) SNOTEL stations directly. The falling SWE trend regionally is consistent with late-season melt-consolidation, but any new storm snow on top of a settling spring snowpack can form reactive slabs, especially on shaded aspects.

Given no bulletin, keep your terrain conservative. Stay on slopes under 35 degrees, avoid convexities and lee aspects above treeline after wind events, and be aggressive about your turnaround time on sunny days — wet loose hits fast in late April once the solar radiation gets going. The long daylight window (6:37 AM to 8:14 PM) is your friend for early starts. Be on your summit terrain by 9–10 AM and descending by noon. Saturday night's snow cycle could refresh things for Sunday, but also reset whatever stability had been building — reassess in the field.
