PORTLAND, Ore. (KATU) — We are continuing to watch an area of low pressure that is forecast to move up the Oregon coastline on Wednesday, bringing the potential of high winds in the Willamette Valley and... WEATHER | Latest Storm Tracker 2 Forecast The National Weather Service in Portland has issued a Wind Advisory for Wednesday beginning at 7 a.m. NWS meteorologists say that south winds of 10 to 25 mph are likely with gusts up to 45 to 55 mph. Here in the Storm Tracker 2 Weather Center, our in-house model, the Baron 3km, also says wind gusts that high are likely.

On Wednesday morning. winds will initially start coming from the east before turning quickly to the south as the low moves north. WESTERN WASHINGTON — The gift that no one wanted - a Christmas Eve windstorm that could mean widespread power outages - won't be delivered. The National Weather Service (NWS) in Seattle has canceled the Wind Advisory that was in effect for much of King County and western Washington for the afternoon and evening. A low-pressure system predicted to move through the area has weakened considerably and will not produce significant wind. The NWS said there may be some localized breeziness, but widespread damaging winds are no longer expected.

For Christmas morning, be ready for a stray shower and watch for slippery conditions on Snoqualmie Pass as mountain snow will continue. A large upper level low is just offshore of northern California and is slowly moving northward into Wednesday. The strong system will move along the I-5 corridor right into western Washington, bringing a strong round of winds for Christmas Eve Day. SEATTLE - In the morning, the strongest winds are focused over the Cascade gaps (e.g. North Bend and Enumclaw). We've seen forceful gusts to 60+ mph over Crystal Mountain and the South Cascades.

By the afternoon, there's a chance for more forceful winds — this time, coming from the south. The second period of winds will have a higher impact with gusts potentially reaching 35–45+ mph. Some communities could see gusts exceeding 50 mph. There could be tree damage and power outages. There are widespread Wind Advisories in effect. The High Wind Warning, earlier in effect for much of I-5 in Seattle, has been canceled and downgraded.

The weather models are somewhat split as to the path of this storm: the impacts of this system depend on where it moves. If the low pressure moves over the coast alone, the winds would be more damaging. However, if it moves farther east, the winds would likely be weaker. Some models suggest very little wind while others expect more forceful gusts. As a result: this forecast has a high 'bust potential' — meaning, the winds could be a dud, barely blowing — or gusts could be stronger. I recommend preparing for the worst-case scenario and being pleasantly surprised if conditions are quieter.

A strong atmospheric river will continue heavy rain over southern California through Friday. The heaviest rainfall is ongoing today in the Los Angeles Basin. Flash and urban flooding is possible. A prolonged heavy snowfall has begun over the Sierra Nevada Mountains and will continue through Friday. Travel will become increasingly difficult over the passes due to snow and strong winds.
