Laurin Girgis reporting for the Seattle Times:
Friday’s rain and gusty winds will continue through the weekend, with somewhere between half an inch to 1 ½ inches of precipitation accumulating in Seattle over Saturday and Sunday.
National Weather Service meteorologist Dev McMillian said Friday’s torrent of rain and wind came from an atmospheric river: a long band of moisture stretching across the Pacific Ocean and resulting in large amounts of precipitation. Saturday and Sunday, despite more precipitation coming in, will not be an atmospheric river, McMillian said. Rainfall rates Saturday through Monday are expected to be less than Friday.
