Thanks to the AMC Hermit Lake , Randolph Mountain Club Gray Knob and Harvard Cabin caretakers for taking measurements so early every morning. This information is a valuable tool in helping MWAC produce more accurate avalanche forecast. Please thank the caretakers when you see them!
This website is provided through a partnership between the White Mountain National Forest and the White Mountain Avalanche Education Foundation. The avalanche forecast applies only to backcountry areas, not operating ski areas, and describes general avalanche conditions which vary locally.
