Avalanche Forecast

OLYMPICS

WASHINGTON CASCADES NEAR AND WEST OF THE CREST

Tuesday to Wednesday morning: Moderate avalanche danger above 5000 feet
and low below.

Wednesday afternoon and night: Avalanche danger becoming considerable
above 4000 feet and moderate below.

WASHINGTON CASCADES EAST OF THE CREST

Tuesday to Wednesday morning: Moderate avalanche danger above 6000 feet
and low below.

Wednesday afternoon and night: Avalanche danger becoming considerable
above 5000 feet and moderate below.

Snowpack Synopsis

Mostly light amounts of snow have been seen so far in February with
extended periods of light winds and mild temperatures. This should have
caused layers in most areas to mostly stabilize. There have been almost
no reports of avalanches for several days. Any lingering unstable
layers should be most likely on steep north to northeast slopes at
higher elevations.

Tuesday to Wednesday morning

Fair weather should be seen during this period with generally safe
avalanche conditions. Sun effects may slightly increase the avalanche
danger on steep sun exposed slopes. Watch for unstable snow on the
steepest lee terrain features.

Wednesday afternoon and night

Increasing winds and increasing rain or snow is expected with a warming
trend. This should begin to build new unstable layers on lee slopes
especially at higher elevations. An increasing avalanche danger should
be seen later Wednesday.

NWAC weather data and forecasts are also available by calling
206-526-6677 for Washington, 503-808-2400 for the Mt Hood area, or by
visiting our Web site at [1]www.nwac.us. Remember that these avalanche
forecasts apply to back country avalanche terrain below 7000 feet
outside of developed and operating ski areas or highways.

The NWAC program is administered by the USDA-Forest Service. NWAC
forecasts, data and avalanche or mountain weather information are made
possible by partnerships between the Forest Service and many important
cooperators, including the National Weather Service, Washington State
Department of Transportation, Washington State Parks and Recreation
Commission, Washington Snowparks and Snowmobile Grants, National Park
Service, Ski Washington, Pacific Northwest Ski Area Association, the
Friends of the Avalanche Center and others.

This forecast is prepared for cooperators and users of the NWAC, as an
aide to tranportation and recreational operations, and to help promote
public safety in the NW mountains.

   operates out of the National Weather Service Forecast Office in
   Seattle. NWAC services are made possible by important collaboration and

Avalanche Forecast

                                  OLYMPICS-

               WASHINGTON CASCADES NEAR AND WEST OF THE CREST-

   Monday and Tuesday: Moderate avalanche danger above 4 to 5000 feet and
   low below slightly increasing late morning and afternoon hours,
   slightly decreasing overnight.

                   WASHINGTON CASCADES EAST OF THE CREST-

   Monday and Tuesday: Moderate avalanche danger above 5 to 6000 feet and
   low below slightly increasing late morning and afternoon hours,
   slightly decreasing overnight.

Snowpack Synopsis

   Several weak weather disturbances have moved across the region during
   the past week in a generally weak split upper level flow. These
   weakening weather systems produced intermittent and generally minor new
   snow accumulations. The most recent weak disturbance moved northward
   through the area mid-late Saturday through early Sunday, producing
   another 1 to 2 inches of relatively soft new snow. While little change
   in freezing levels occurred with most of the disturbances. some brief
   increases in ridgetop winds produced shallow wind slabs and a moderate
   danger, mainly on higher elevation, lee slopes. At mid and lower
   elevations and on sun exposed slopes and beneath trees, the combination
   of multiple soft layers interspersed with thin weak crusts over an old
   stronger crust region is producing mostly stable snow but some marginal
   downhill conditions.

Monday and Monday night

   Partly cloudy skies Monday morning should be followed by gradually
   increasing clouds Monday afternoon...especially in the south...along
   with a chance of scattered light showers, light winds and little change
   in the freezing levels. This weather should briefly increase the danger
   on sun exposed terrain and maintain or slightly increase the danger at
   higher elevations on lee slopes. Although increasing clouds are
   expected late Monday along with some light snow or snow showers
   overnight...mainly in the south...little or no accumulation is
   expected. As a result, a slight decrease in the overall danger is
   anticipated Monday night.

Tuesday and Tuesday night

   Partly cloudy skies are expected in the northern and central Cascades
   and Olympics early Tuesday with decreasing clouds and light showers in
   the south. This should be followed by partly to mostly sunny skies
   mid-day and early afternoon with increasing clouds likely later
   Tuesday, mainly in the north. Along with light winds, little change in
   the freezing levels, and a few light showers in the north late Tuesday,
   this weather should produce a slight increase in the danger during the
   late morning and afternoon hours, especially on sun exposed terrain,
   with a generally decreasing danger expected overnight.

   NWAC weather data and forecasts are also available by calling
   206-526-6677 for Washington, 503-808-2400 for the Mt Hood area, or by
   visiting our Web site at [1]www.nwac.us. Remember that these avalanche
