About 185,000 homes and businesses remained without power in Washington state late on Wednesday, after a storm blew down trees and triggered mudslides, killing at least three people, authorities said. Governor Jay Inslee declared a statewide emergency because of the storm, which left a wide swath of the Puget Sound region under flood watches and warnings. In the Spokane area of eastern Washington, utility Avista warned it could take three to five days to restore services to nearly 115,000 customers without power.
