The storm caused widespread power outages, with up to 42,000 customers initially affected in Seattle and surrounding areas. Downed trees and power lines created hazardous conditions, particularly in South Seattle, West Seattle, and Burien. Roadway flooding and ponding were also reported due to heavy rain and fallen leaves clogging drains, increasing the risk of accidents for drivers. While power restoration efforts have been largely successful, residents are advised to remain cautious as additional rain is expected in the coming days.
