The National Weather Service reported that the Seattle area had received more than 2 inches of rain as of Friday morning, breaking a previous record for Dec. 20 rainfall that was set in 1955.
Weather service meteorologist Kirby Cook told our online news partner The Seattle Times that the cause of all this moisture is an atmospheric river, a deep plume of warm moisture coming off the Pacific from the southwest.
