Points saillants

Monday will be a great day - to avoid travel in avalanche terrain. Heavy rain will maintain very dangerous avalanche conditions at middle and upper elevations. Stay out of all areas where avalanches can start, run, or stop.

    Wet slabs are notoriously hard to forecast, but more rain and high freezing levels will certainly help maintain the threat of large, deadly wet slab avalanches. These types of avalanches are not the kind you tip-toe around. You are either in the way or not. Any slope above 35 degrees and the run-out of large avalanche paths - should all be considered suspect. The best policy will be to simply avoid travel on or near steep slopes that could avalanche. 

    Observers have also reported widespread wet loose avalanches. While less destructive, you should still consider these in your tour planning. Some of these could grow large enough to ruin your day.

Avalanche Discussion

Sunday was a wet one! Weather stations across Mt Hood recorded nearly 4 inches of rain in the last 24 hours. And the active cycle is still far from over. We may see a short break in precipitation during the early morning hours, but rain is forecast to pick right back up on Monday. Expect another 1-1.5 inches of rain throughout the day.

Leading up to this active cycle, observers reported endless signs of instability such as shooting cracks, propagating test results, heavy drifting, and recent avalanches. Continued rainfall on this snowpack will maintain very dangerous conditions through the early week. 

If you get out into the mountains, let us know what you see by submitting a public observation.
