Today's Forecast

Updated Friday 3:05 p.m.

Are we sure tomorrow is August 29th? I mean... really sure?

Because there are now Wind Advisories up for Saturday as a powerful storm (especially by August standards) comes ashore. It's straight out of November's playbook.

Rain will be developing overnight with lows in the upper 50s.

The storm will reach the north Oregon Coast first around daybreak, bringing wind gusts as high as 65 mph down there. It'll then make landfall around Hoquiam later in the morning with gusts to 45 mph along the rest of the coast.

Winds will rapidly ramp up around noon in the Seattle area, maybe a little before, as the storm then moves just north of the Puget Sound region. It will be weakening as it does so, but we'll still get a good three hours of strong winds, gusting to about 30-45 mph across the metro area, slowly tapering as we get into the evening. A WIND ADVISORY is in effect from 11 a.m. to 5 p.m. for the Puget Sound region.

The winds will linger a bit longer in the North Sound regions up to the Canadian border, where the Wind Advisory is in effect until 9 p.m. Saturday.

The trees are still heavy and full of leaves, and the first windstorm of a season tends to be the one to break off all the more susceptible branches that weakened over the summer. Thus, we tend to see more damage with lower wind speeds early in the season then in late fall and winter when the trees are bare, and it's a good idea to be prepared for scattered power outages in the midday and afternoon hours.

And don’t forget the rain! Steady, moderate-to-heavy rains will be around for much of the day -- many areas could see an inch or more of rain through the day.

Winds and rain will calm down Saturday night.

We'll call it a relative lull for Sunday, but it'll still be cool and cloudy with frequent light showers through the day. Highs both days will be in the mid-upper 60s.

Another wave of light rain returns for Monday and stalls over the region for Tuesday. This will just be typical Seattle light rain and much less stormy. Highs will stay in the mid-upper 60s.

Showers and sunbreaks will be more the rule for the balance of the week with highs in the upper 60s to near 70. So while it might seem like Thanksgiving time around here, remember you do only get one extra day off for Labor Day :)
