ESFPQR An series of frontal systems will bring heavy rainfall to northwest Oregon and southwest Washington this weekend. Rain will begin Saturday afternoon, and intensify overnight through Sunday. This will lead to rises on rivers and creeks, especially along the coast on February 22nd through the 23rd. Main stem rivers may be delayed to respond, and flooding may occur beyond this time frame. There is around a 20-25% chance of the Wilson River, the Grays River, and other localized quick responding coastal rivers of reaching minor flood stage on Sunday. Confidence in flooding is low as the location of heaviest precipitation will greatly depend on where the warm front sets up. In the case that this system over performs, more widespread flooding is possible. Heavy rainfall along the Cascades is expected and combined with recent snow accumulation, there is elevated landslide risk. Heavy rainfall may also lead to ponding of water, general lowland flooding, and localized urban flooding, especially in low-lying areas or other poor-drainage areas. Heavy rainfall will also increase the potential for landslides in areas of steep terrain and debris flows over areas that have been burned by wildfires over the past few years. Shifts in the forecast storm track can change the outlook and probabilities for river flooding, so be sure to monitor weather.gov/portland for the latest weather updates, as well as any watches, warnings, or advisories that may be issued.

ESFPDT What: The precipitation and snow melt will lead to rises on area creeks, streams and rivers. Rivers are low enough that only the Naches River at Cliffdell is expected to exceed bankfull early Monday for a few hours and only by a few inches. However, with the heavier periods of rain and snow melt, rapid rises will be possible on smaller streams and creeks as well. Further rises on streams and creeks will be a concern through the weekend into early next week. When: Rain will be ending tonight though more systems will bring rain Friday night through Monday. Where: The Upper and Lower 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. Synopsis: Rain and high mountain snow in the last 24 hours and multiple systems this weekend and early next week will lead to rising water levels on area streams and rivers. Rainfall amounts of 2 to 4 inches are expected in the Cascades and 1 to 2 inches in the eastern Oregon mountains. In addition, temperatures will be rising to the 40s and even lower 50s in the mountains which will lead to snow melt adding even more water to rivers and streams. At this point, the Naches River at Cliffdell is expected to barely reach action stage for several hours early Monday before receding. Other rivers in the Cascades and eastern Oregon mountains are forecast to approach but stay below action stage. Rises will also be possible on smaller streams and creeks. This Hydrologic Outlook will be updated as needed due to changing conditions.

ESFSEW A series of storms will begin to impact western Washington on Friday and continue through Tuesday. The next storm on Saturday will have heavy rain at times as will a third storm right on its heels Sunday. Precipitation amounts could be 3 to 8 inches storm total with snow levels rising above 6000 feet. With moderate temperatures now and warmer temperatures to come, this will also result in a some snow melt at low to mid elevations. These factors will combine to result in a potential for river flooding. At this time the most likely flood severity will be minor flooding.There is also a Flood Watch out for Mason County, including the potential for moderate flooding on the Skokomish River. The most likely areas for river flooding will be for rivers flowing off of the central and southern Washington Cascades, the Olympics, and in southwest Washington. Urban and small stream nuisance flooding and rainfall-induced shallow landslides will also be possible.

ESFPQR An series of frontal systems will bring heavy rainfall to northwest Oregon and southwest Washington this weekend. Rain will begin Saturday afternoon, and intensify overnight through Sunday. This will lead to rises on rivers and creeks, especially along the coast on February 22nd through the 23rd. Main stem rivers may be delayed to respond, and flooding may occur beyond this time frame. There is around a 25% chance of the Wilson River, the Grays River, and other localized quick responding coastal rivers of reaching minor flood stage on Sunday. Confidence in flooding is low as the location of heaviest precipitation will greatly depend on where the warm front sets up. In the case that this system over performs, more widespread flooding is possible. Along the Cascades heavy rainfall is expected. Heavy rain combined with recent snow will elevate the landslide risk. Heavy rainfall may also lead to ponding of water, general lowland flooding, and localized urban flooding, especially in low-lying areas or other poor-drainage areas. Heavy rainfall will also increase the potential for landslides in areas of steep terrain and debris flows over areas that have been burned by wildfires over the past few years. Shifts in the forecast storm track can change the outlook and probabilities for river flooding, so be sure to monitor weather.gov/portland for the latest weather updates, as well as any watches, warnings, or advisories that may be issued.

What: An atmospheric river will deliver warm, rainy, and breezy weather to the region this weekend into early next week. High temperatures Sunday and Monday will warm into the upper 40s to low 50s. Additionally, rainfall amounts of 0.60 to 1.25 inches in the lowlands and 1 to 2 inches in the mountains are currently forecasted. Rapid lowland snowmelt will lead to rises on area creeks, streams, and rivers. Paradise Creek in Moscow is currently forecasted to reach Minor Flood Stage Sunday morning. Hangman Creek in Spokane, Little Spokane River at Dartford, and South Fork Palouse River at Pullman are forecasted to rise to near bankfull conditions on Sunday. Minor field flooding and ponding of water in areas of poor or clogged drainage will also be a concern. When: Beginning Saturday evening and continuing through Monday. Heaviest rainfall will occur in two rounds: Saturday night into Sunday morning and Sunday afternoon into early Monday.
