A powerful wind storm rolled through the Pacific Northwest leaving a trail of damage, including nearly blowing a semi off a bridge, a landslide and more than 500,000 people without power. Winds reached gusts 50-70 mph in parts of the Puget Sound region. Ferndale reported a gust to 70 mph. In Oregon, Dodson residents were told to evacuate after the National Weather Service issued a flash flood warning Wednesday morning. Eastbound Interstate 84 in Oregon was closed at the Troutdale exit after a landslide spilled onto the freeway near Dodson earlier in the morning.
