Two human-triggered avalanches occurred at Tuckerman Ravine on New Hampshire’s Mount Washington Sunday morning, and officials warn that the area’s avalanche danger will increase rapidly on Monday.
Nobody was caught in the avalanches and there were no injuries.
Officials with the Mount Washington Avalanche Center say that the avalanche danger will increase rapidly today as the wind shifts to blow from the west while increasing in speed. This will move new snow, building new wind slabs that will quickly get bigger and become likely to be triggered by people.
Wind-loaded terrain is likely to reach considerable avalanche danger by late afternoon or evening. This danger rating is largely driven by a weather forecast predicting shifting winds.
Officials warn that wind can take just a few inches of new snow and easily build slabs that are several feet thick.
