ESFPDT 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.

AVWPQR 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 information. Similar avalanche danger may exist at locations outside the coverage area of this or any avalanche center.

Rain, breezy winds, high temperatures in the upper 40s to low 50s, and overnight temperatures above freezing will contribute to rapid lowland snowmelt. - http://www.weather.gov/safety/flood

* WHAT...Southwest winds 35 to 45 mph with gusts up to 65 mph possible. * WHERE...Portions of Lake, Klamath, and Modoc counties, including Summer Lake, Wagontire, Valley Falls, Paisley, the Warner and Hart Mountains, Winter Rim, and portions of Highways 395, 140, and 31. * WHEN...From Monday morning through late Monday night. * IMPACTS...Damaging winds could blow down trees and power lines.

Isolated power outages are possible. Travel could be difficult, especially for high profile vehicles.

* WHAT...Flooding caused by excessive rainfall continues to be possible. * WHERE...Portions of northwest Oregon and southwest Washington, including the following counties, in Oregon, Benton, Clackamas, Clatsop, Columbia, Cowlitz, Hood River, Lane, Lincoln, Linn, Marion, Multnomah, Polk, Tillamook, Washington, and Yamhill. In Washington, Clark, Pacific, Skamania, and Wahkiakum Lowlands. * WHEN...From late tonight through late Tuesday night. * IMPACTS...Excessive runoff may result in flooding of rivers, creeks, streams, and other low-lying and flood-prone locations, especially for rivers draining the Willapa Hills and Oregon Coast Range. Flooding may occur in poor drainage and urban areas. Landslides are possible through this period, especially over the Cascades due to heavy rainfall above 7,000 feet combined with snowmelt. There is low probability for debris flows as rainfall rates are not expected to meet thresholds over recently burned areas. * ADDITIONAL DETAILS... - An atmospheric river and series of frontal systems will produce periods of heavy rainfall over northwest Oregon and Southwest Washington through Monday. The heaviest rain will be over the coast, Coast Range, Willapa Hills, and Cascades where rain totals from Saturday through Monday night will range from 3 to 6 inches, with locally higher amounts possible. Snow levels will rise to above 7,000 feet on Sunday, and snow melt due to rain falling on the Cascade snow pack could cause additional flooding concerns for drainages from the Cascades along with enhanced risk of landslides. - http://www.weather.gov/safety/flood
