I'm having a hard time with this being a DAY HIKE, they are ABOVE treeline, a storm (probably a forecast store at that) hits, they are lost, etc, and it is already AFTERNOON. My day hike would have me well below treeline by afternoon, I would have checked the weather before going up there in the first place, and of course I would have a map, compass, and GPS along...
