support from a variety of federal, state and private cooperators.

ORZ-011

Avalanche Forecast

MT HOOD

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.

ORZ-011

Avalanche Forecast

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 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 some mostly shallow and somewhat isolated soft
wind slabs above about 5 to 6000 feet, mainly on northwest through
northeast facing slopes. At mid and lower elevations and on sun exposed
slopes and beneath trees, the combination of multiple soft layers
interspersed with weak crusts over an old crust region is producing
more stable snow but some locally marginal downhill conditions.

Monday and Monday night

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

Tuesday and Tuesday night

Decreasing clouds and light showers early Tuesday should be followed by
partly to mostly sunny skies mid-day and early afternoon with variable
high clouds later Tuesday. 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.
