Arctic air plunges south as residents of the Pacific Northwest remain on guard after severe flooding

A blast of arctic air is plunging south from Canada and spreading into parts of the northern U.S., while residents of the Pacific Northwest brace for possible mudslides and levee failures from floodwaters that are expected to be slow to recede. The catastrophic flooding has forced thousands of people to evacuate, including Eddie Wicks and his wife, who live amid sunflowers and Christmas trees on a Washington state farm next to the Snoqualmie River.
