Teton Pass Backcountry

The Bridger-Teton Avalanche Center hasn't issued a danger rating for this period, which at this point in late April likely means they've moved to an end-of-season advisory mode rather than daily bulletins. That shifts full responsibility for hazard assessment onto you in the field. The standard late-season red flags apply: recent shooting cracks, whumping, or any evidence of recent avalanche activity should be your hard stop signals. The BTAC's own language says 'watch for signs of unstable snow and avoid traveling on or under similar slopes' — that's about as minimal as guidance gets, so treat it as a heads-up that they're not watching the snowpack for you anymore.

Weather is the main planning variable this weekend. Today has a 74% precip chance and light WNW winds at 7 mph — manageable, but visibility will be limited during showers. Tonight clears out significantly (20% precip, dropping to 13°F), which is your best window. Saturday looks workable with only scattered showers at 30% and light SSW winds, but Saturday night picks back up to 37%. Sunday is the one to watch: 82% precip chance, 35°F high, NW winds — that combination means new loading on a late-season snowpack that may have significant solar-weakened layers underneath. If you're planning a bigger objective, do it Saturday, not Sunday.

The SNOTEL data here is mismatched — the stations reporting (Annie Springs at 6,021 ft in Oregon, Long Lake at 840 ft, McNeil Canyon) are not Teton Pass stations, so treat that snowpack depth data as noise. The 37-inch depth flagged for your location is a reasonable late-April snowpack for Teton Pass at mid-elevation, but you'll want to verify coverage on south aspects, which are likely punchy or bare by now. The temperature pattern — highs in the mid-30s — means wet snow surface conditions by late morning on sun-exposed terrain. Plan your descents on solar aspects before 11 AM.

Stream crossing data is California gauges and irrelevant to your trip. Daylight is excellent — nearly 14 hours, with sunset at 8:18 PM — so you have no pressure on timing from that angle. Get your high-angle objectives done Friday evening or Saturday morning during the weather window, dig a pit before committing to anything steep, and be off significant terrain before Sunday's precip cycle loads up.
