The National Weather Service in Seattle has issued a Wind Advisory to take effect from 10 PM this evening to 10 AM PST Sunday morning.

Winds from the South 20 to 35 mph could gust up to 50 mph. in areas like Hoquaim, Forks, Olympia, Tacoma, Seattle, Bremerton, Everett, Whidbey Island, Friday Harbor, Bellingham.

South winds will rapidly develop late this evening or early Sunday morning then ease late Sunday morning. For most of the area, the strongest winds will occur in the early morning
hours on Sunday.

Winds may snap tree branches and cause local power outages.

A Wind Advisory means that winds of 35 mph are expected. Winds this strong can make driving difficult, especially for high profile vehicles. Use extra caution.

 

Forecasters at the National Weather Service in Seattle say the flow is offshore today, ahead of the next approaching system. South winds will increase tonight as this system tracks north into Western WA. This will bring a burst of gale force winds over all waters, mainly between 06-12z. Winds will gradually ease Sunday morning, but still likely remain within Small Craft Advisory range, as this system exits. The flow will turn offshore again late Monday and Tuesday as the next Pacific storm system spirals offshore. Small Craft Advisory winds are likely over the Coastal Waters. 33

Current models look consistent with previous solutions regarding the approach of the next system…with precip associated with the trough making it to the coast this afternoon and seeping further inland this evening before becoming more widespread tonight. This will lead to some accumulations in the Cascades…with amounts around Mts. Baker and Rainier crossing over into Advisory thresholds. The passes…on the other hand…look to get a bit of a pass…with only 2-4 inches expected there. The most interesting feature with this system continues to be a strong pressure gradient as the system moves inland…resulting in windy conditions during the overnight hours tonight and into Sunday morning before tapering off by late morning.

The trough will traverse the area Sunday keeping precip in the forecast exiting the area by early Monday morning. Although some shortwaves may allow for lingering precip into Monday morning…this appears to be relegated mostly to the Cascades. And while snow levels in the wake of the exiting trough will drop down to around 1000 ft…the fact that the main threat of precip will have already moved on makes any thoughts of lowland snow extremely unlikely. To further cement that…an upper level ridge will build over the area through the day Monday…making for generally dry conditions and allowing snow levels to start to rebound.

.LONG TERM /TUESDAY THROUGH FRIDAY/…From Previous Discussion…A frontal system will bring another round of rain Tuesday and Wednesday. A deep surface low tracking to the northeast over the Offshore Waters will bring another windy period to parts of the area, especially Wednesday. Another system could bring more rain and wind Thursday but models are struggling with the details. Models suggest an upper ridge could bring drier weather by the end of the week.
