Avalanche Summary
Anticipate rising avalanche danger throughout the day. You can trigger a large and dangerous avalanche where you find more than about 10 inches of new snow. Pay attention to changing conditions and assess the slopes you plan to travel for snow accumulation throughout the day. If you observe signs of instability like cracking in the new storm snow, move to a lower angle slope.
Avalanches in the new snow could step down to buried February weak layers, causing a larger slide that propagates widely. This is most likely in shallow areas near trigger spots like exposed rocks and below ridges and cliffs.
