Synopsis: Rain and high mountain snow this weekend and early next
week will lead to rising water levels on area streams and rivers.
Total rainfall amounts of 2 to 5 inches are expected in the Cascades
and 1 to 3 inches in the eastern Oregon mountains. In addition,
temperatures rising to the 40s and lower 50s in the mountains will
lead to snow melt adding even more water to area rivers and streams.
What: Precipitation and snow melt due to warmer temperatures this
weekend into early next week will lead to rises on area creeks,
streams and rivers. Many rivers are forecast to reach near or above
bankdfull by Sunday, including the Walla Walla River at Touchet, the
Klickitat River at Pitt, the John Day River at Service Creek, the
Umatilla River at Gibbon, and the Naches River at Cliffdell. Another
concern will be rapid rises on smaller streams and creeks due to
heavier downpours and snowmelt. This could lead to debris flows on
recent burn scars and over steep terrain.
When: Rain will continue through Monday with the heaviest rain
expected tonight and Sunday.
Where: The East Slopes of the Washington and Oregon Cascades, the
Simcoe Highlands, the Northern and Southern Blue Mountains, the Blue
Mountain Foothills of Washington and Oregon, Wallowa County and the
Grande Ronde Valley.
This Hydrologic Outlook will be updated as needed due to changing
conditions.

What: Precipitation and snow melt due to warmer temperatures this

the Klickitat River at Pitt, and the Naches River at Cliffdell are
expected to approach bankfull late Sunday night before receding
Monday and Tuesday. Another concern will be rapid rises on smaller

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 Sat 18:00 PST to Sun 18:00 PST.
* IMPACTS...Very large natural avalanches are expected. These will
be more than enough to bury, injure, or kill backcountry travelers.
* PRECAUTIONARY / PREPAREDNESS ACTIONS...Avoid all areas where
avalanches can start, run, or stop. This includes openings in the
forest well below large steep alpine slopes.
Consult https://www.nwac.us/ or www.avalanche.org for more detailed
