Local paper reported someone set off a PLB on Madison on Sunday evening. The winds currently are 120 MPH plus this morning and -17 degrees F at the summit of Washington and conditions were worse last night, Madison would have similar conditions. Hopefully the hiker dug down in snowbank as even rescue folks will have a tough time even getting up there. Its bright blue skys but looking at the summit cam, there it may be whiteout conditions above treeline due to blowing snow.
