SYNOPSIS
Scattered showers will gradually taper through this evening for a brief lull in between weather systems. A series of weather systems will impact the region over the next week, bringing heavy precipitation and an increased risk of river flooding across western Washington. A brief break in the active weather will be possible late week, before yet another system approaches the region over the weekend.

SHORT TERM /TONIGHT THROUGH TUESDAY/
Latest radar shows scattered shower activity continuing across western Washington this afternoon, with the heaviest band of precipitation currently located along US-2. A Winter Storm Warning remains in effect for the Cascades as a few bands of heavier precipitation may still drop a couple inches of snow through the evening hours. Meanwhile, the Winter Storm Warning for the Olympics has been cancelled this afternoon with only light additional accumulations expected through this evening. Overall, hi-res guidance has showers gradually tapering areawide through this evening for a brief lull in the weather tonight.

The first of 2 atmospheric river systems will move through the region on Sunday, bringing warmer conditions and widespread rain to western Washington. Snow levels are expected to rapidly rise to around 6000-7000 feet by late morning and will bring moderate to heavy rain at times. Even though the majority of the moisture transport will be to the south, there will still be heightened hydrological impacts with rain on top of fresh snow (in the mountains) which will result in enhanced flows and sharp rises on local area rivers. See the hydrology section below for more details. The burn scar landslide/debris flow threat will increase on Sunday as well and the Northwest Avalanche Center continues to highlight the threat for very dangerous avalanche conditions developing.

Rain will linger into Monday, before a stronger, wetter atmospheric river moves into western Washington Monday afternoon into Tuesday.
With snow levels generally hovering between 7000-9000 feet, expect this system to bring another round of widespread rainfall to the area and for it to be moderate to heavy at times. This may lead to minor nuisance flooding of poor drainage areas and could create difficult commute conditions at times. The forecast, however, will remain sensitive to slight changes in QPF, so it will be important to closely monitor the trends over the next few days. Additional rainfall will continue to lead to sharp rises on the area's elevated rivers, with multiple rivers likely to approach flood stage. Winds will also increase area-wide on Monday evening into Tuesday, with wind gusts 25-40 mph possible across the area at times. Highest gusts will be along the Pacific Coast and for areas from Whidbey Island northward. Large waves along the coast will build towards 20 feet on Tuesday and may run up further on area beaches at times.

LONG TERM /WEDNESDAY THROUGH SATURDAY/
Latest guidance continues to suggest another weaker system moving through the area Wednesday into Thursday. Snow levels look to start out between 5000-6000 feet on Wednesday, but look to drop back down to pass level by Thursday - which may account for light snow accumulations.
Precipitation looks to linger into Friday, before a shortwave ridge moves into the area by Friday evening. This currently looks to provide a brief break in the active pattern, before another system arrives over the weekend. There remains uncertainty in the latest deterministic and ensemble guidance on the track and timing of the system late week, so will need to monitor how this trends over the coming days. 14

AVIATION
Northwest flow aloft as weak ridging resides just upstream. Ceilings have improved to VFR as scattered showers continue across the area. VFR conditions will persist into Sunday morning before the next round of rainfall arrives with MVFR with localized IFR, reaching the coast by 08-10z and the interior by 12- 14z. Southerly surface wind gusts up to 20 to 30 knots becoming widespread Sunday afternoon. VFR may return as precip coverage lessens during the afternoon-evening on Sunday as well.

KSEA...VFR ceilings holding into Sunday morning. Then, MVFR cigs look to return 12-14z Sunday as widespread rainfall rebounds. SW winds will decrease and turn more southerly tonight before veering more SW again Sunday afternoon between 10-15 kt with gusts near 20 kt.

MARINE
A series of frontal systems will make their way through the coastal waters from Sunday through Thursday. Gales over the waters have tapered down to Small Craft Advisory levels. SCAs will continue through most of the area waters through Sunday, with a substantial break expected for the Puget Sound/Hood Canal waters late tonight into Sunday morning. Gusty winds may approach gale force for a short period in the East and Central Strait of Juan de Fuca Sunday evening, but have kept SCAs for this update. Another round of gusty winds expected Monday into Tuesday, likely reaching gale force for the coastal waters, the East Strait and into Admiralty Inlet. SCA conditions are expected for the remainder of the area waters.

Seas 15 to 17 feet at 14 s will subside Sunday but remain above 10 feet. A peak to 15 to 18 ft again is expected early Monday, then topping out Tuesday to around 20 ft at 18 to 20 s before slowly ramping down into the end of the week.

HYDROLOGY
A series of weather systems will move through Western Washington through Tuesday bringing multiple rounds of rain. A Flood Watch remains in effect for the area from tonight through late Wednesday night. While snow continues to fall in the mountains this afternoon, warmer and wetter systems will move into the area Sunday through Tuesday. Snow levels will rise rapidly to 5000 to 7000 feet Sunday morning. Snow levels will then continue to rise peaking generally around 8500 to 9500 feet Monday night. Rainfall totals in the mountains for Sunday through early Wednesday generally range from 10 inches in the higher elevations of the Olympics and Cascades, 5-8 inches for the foothills, 2-4 inches for the interior lowlands, and 4-6 inches for the coast. The combination of heavy precipitation and rising snow levels will most likely result in river flooding on many rivers across western Washington. Rises on the Skokomish River will be possible with the first system on Sunday. Other rivers currently look to reach flood stage on Tuesday. Moderate flooding is possible on some of the bigger rivers like the Snoqualmie, Snohomish and Skagit as well as the lower reaches of the Chehalis beginning Tuesday. While flooding looks likely across the region, there remains a degree of uncertainty in the scope and extent due to timing of the snow to rain switchover in the high elevations and uncertainty in the locations of the heaviest bands of precipitation. It will be important to stay up to date on the latest forecast developments over the weekend.

In addition to the river flooding, burn scars in the Cascades will have to be monitored with the heavy precipitation forecast. Elevated risks of landslide and debris flows will also be possible next week. 14/Felton
