A series of mudslides on the rail lines south of Everett have triggered the latest closure of the Sounder Northline that will remain in effect Thursday night and all day Friday.
A spokesperson for BNSF railroad said there have been 11 slides in the past 24 hours along that stretch of tracks - including eight on Thursday alone - making this one of the worst years for mudslides there in the past 20 years.
Further north, the Mount Baker Highway has been closed east of Maple Falls indefinitely after more than 100 trees came down in a 48-hour period. More trees are continuing to fall, officials said, and because it is so windy, it is unsafe for crews to work in the area.
With access cut off, the Baker Ski area also is closed.
Farther west, Highway 101 and Highway 106 in Mason and Jefferson counties have been closed near Hood Canal, state Department of Transportation officials said.
Crews are now on-site, clearing trees brought down by heavy snow and winds. The highways will be closed until further notice while the clearing work continues.
Transportation officials said four miles of Highway 101 is closed near Brockdale Road north of Shelton. In addition, about 25 miles of Highway 101 is closed between Potlatch in Mason County and Brinnon in Jefferson County.
About five miles of Highway 106 is closed between the Purdy Cutoff Road and Dalby Road.
Officials said crews will concentrate on clearing Highway 101, then go to work on reopening Highway 106.
There was no estimate for when the highways would be opened to traffic.
