Dense freezing fog with visibilities of a half mile or less will continue to impact portions of the Washington Columbia Basin through this morning. The densest fog has been observed from Grandview to the Tri-Cities, including across the Hanford area. Morning commutes along I-82, US-395, route 240, and in the Tri- Cities area may be impacted.

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.

* WHAT...Visibility one quarter mile or less in dense freezing fog. * WHERE...Rockford, Hayden, Post Falls, Davenport, Cheney, Spokane Valley, Othello, Downtown Spokane, Ephrata, Moses Lake, Quincy, Airway Heights, Fairfield, Worley, and Coeur d'Alene. * WHEN...Until 9 AM PST this morning. * IMPACTS...Low visibility and freezing fog will result in slick and hazardous driving conditions.

Patchy fog has developed between Yakima and Prosser. The fog will persist into the nighttime hours. Use low-beam headlights when driving and slow down when encountering fog.

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.

* WHAT...Flooding caused by excessive rainfall is possible. * WHERE...A portion of northwest Washington, including the following county, Mason. * WHEN...From Saturday afternoon through Wednesday afternoon. * IMPACTS...Excessive runoff may result in flooding of rivers, creeks, streams, and other low-lying and flood-prone locations. Creeks and streams may rise out of their banks. * ADDITIONAL DETAILS... - A series of storm systems will impact the Olympics starting Friday and lasting through Tuesday with the bulk of the heaviest rain Saturday and Sunday. 4 to 6 inches are possible during that period alone with 3 to 8 inches storm total possible. In addition, snow levels will rise to 6000 feet resulting in most precipitation falling as snow and adding snow melt to the rainfall. Moderate flooding is possible on the Skokomish River. - http://www.weather.gov/safety/flood

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. Please monitor the latest river forecasts from the National Weather Service for additional information.
