The Washington State Department of Transportation will close Highway 542 at milepost 37 east of Glacier at 4 a.m. on Thursday, January 23, as forecast warming and intense rain on heavy snow creates an avalanche risk along the highway.
If necessary, WSDOT will close the highway earlier, according to a press release. The highway will stay closed until the avalanche risk subsides. WSDOT anticipates the closure will last at least 24 hours, according to the press release.
The closure is about three miles east of Glacier.
The Mt. Baker Ski Area will also be closed on Thursday, but plans to reopen on Friday, according to the ski area’s Facebook page.
