Travel and Terrain Advice
Further rainfall this morning will have created conditions similar to the previous few days. We can expect the upper snow pack to be saturated and heavy today on all aspects below 1200 meters. The overall snow pack height has been reducing resulting in natural hazards such as creek crossings and vegetation becoming a hazard. As the freezing level lowers a surface freeze may occur above 500 meters creating a breakable crust late in the day.

点発生湿雪雪崩 Wet Loose snow
Expect wet loose activity in steep terrain on all aspects below 1000 meters. Be mindful of terrain traps below you, especially creeks or hollows.
