Mt Hood
Danger d’avalanche
Points saillants
Challenging travel conditions are the most hazardous part of the forecast for the holiday Monday. Use caution while traveling on steep open slopes where it may be difficult to arrest a fall and watch for low snow and exposed ground hazards at lower elevations.
Avalanche Discussion
Travel conditions likely continue to be your biggest hazard on Monday. Expect firm and icy slopes from refrozen surfaces after last week's rain event. Sunday's breezy weather kept many surfaces from softening despite temperatures as high as the low 40's. The wind should be less of a factor on Monday and allow the sun to soften the surface eventually. Breakable crusts may be found at lower elevations as well as open creeks and exposed ground hazards from low snow cover.
An observer from Portland Mountain Rescue described conditions above NWAC's forecast area as "extremely icy surface conditions resulting in difficult skiing, tedious cramponing, and a low likelihood of successfully self-arresting." Use extreme caution if you plan to venture onto steep open slopes on the upper mountain.
At lower elevations and later in the day, watch for weakening snow surfaces on slopes receiving direct sunshine or where temperatures rise above freezing. Roller balls are often the first indication that you could trigger a wet loose avalanche. Choose lower angle, or shaded slopes if you see evidence of weak snow surfaces. At higher elevations, you may find firm and icy slopes where a slip could turn into a consequential tumble. Be prepared to self-arrest or choose less exposed travel options.
-Previous Discussion-
Multiple large avalanches have been observed around Mt Hood from the significant rain event last week. Although this does not speak to current conditions public observations are worth a look! A very large avalanche in White River and Newton Canyon. They also observed glide cracks at these upper elevations proof that free water was running at the base of the snowpack.
During the ongoing Covid-19 pandemic, continue to follow the latest guidance from local, state, and federal health officials. Avoid unnecessary risks that could impact first responders and stress medical resources. Wear a mask when appropriate, practice social distancing, and consider recreating closer to home.
