The following message is transmitted at the request of the
Northwest Avalanche Center.
…The Northwest Avalanche Center in Seattle has issued an Avalanche
Warning…
* WHAT…Very dangerous conditions are expected overnight and
continue into Sunday as heavy wet snow and rain overload a dry and
weak snowpack. Very large natural avalanches may occur and could
descend into lower elevation forested areas.
* WHERE…Areas near Mt Hood, Stevens Pass, Snoqualmie Pass, and the
west slopes of the Cascades from I-90 to the Columbia River,
including Crystal Mountain, Mt Rainier, White Pass, Mt Saint
Helens, and Mt Adams. As well as the East slopes of the Cascades
from the Canadian border to Lake Chelan, including Washington
Pass, Methow Valley, and Twisp areas.
* WHEN…In effect from Saturday 600 PM PST to Sunday 600 PM PST.
* IMPACTS…Very large natural avalanches are expected. These will
be more than enough to bury, injure, or kill backcountry travelers.

avalanches can start, run, or stop. This includes openings in the
forest well below large steep alpine slopes.
