An Avalanche Watch is in effect for the Flat Top Mountains. New snow and strong winds will create very dangerous avalanche conditions starting Friday night and lasting through Monday. Travel in avalanche terrain is not recommended during this time.
Heavy snow on Thursday night means you can easily trigger an avalanche on Friday. Avoid steep slopes where you find more than about ten inches of new snow. You'll trigger slides more easily on drifted slopes. You can recognize drifted slopes by fresh cornice development and their pillow-like appearance. Any slide you trigger near the surface can easily step down and grow larger and more dangerous. If you notice signs of instability like cracking in the new snow and audible collapses, then move to slopes less than about 30 degrees.
