In sintesi

Cooler overnight temperatures will create a melt freeze crust from the alpine to treeline. The hazard is reduced while this crust is intact. Warm temperatures, sun exposure and precipitation in the form of rain will increase the hazard rapidly.

    The freezing level will drop below treeline Thursday with rain turning to snow overnight. Expect continued unstable isothermal conditions below treeline, possibly extending to treeline as temperatures increase during the day.
