Northern San Juan

Warmer temperatures and ample sunshine makes wet avalanche activity the primary concern for Wednesday. Start and end your day early reduce this threat. Rollerballs, pin wheels, and a slushy unsupportable surface all mean it's time to move to colder, shadier slopes or exit avalanche terrain.

There is a lingering threat for Wet Slab avalanches. Collapsing and cracking is a clear sign that wetted weak layers just under the surface crusts are capable of producing avalanches. Rocky areas in easterly-facing terrain are most worrisome.
