Travel and Terrain Advice

Storm slab size and sensitivity to triggering will likely increase through the day.

As the storm slab problem gets trickier, the easy solution is to choose more conservative terrain.

Be especially cautious as you transition into wind affected terrain.

Dial back your terrain choices if you are seeing more than 20 cm of new snow.
