SEATTLE, WA — A wild round of weather Thursday brought major flooding to portions of King County, and pushed rivers above flood stage throughout Western Washington. The National Weather Service says we're not out of the woods yet.

More rain is expected through Friday afternoon, ahead of a new system set to arrive Friday night and continue into Saturday. According to NWS forecasters, new rainfall amounts will not be as significant, but saturated soil will continue to pose landslide risks. A flood watch remains in effect until 4 p.m. Friday.

Sound Transit said north line Sounder service would not run Friday morning due to the increased risk of further mudslides.
