Snowpack Discussion

The most recent significant snow from one week ago was in the 5-6 inch range at Mt Hood. Since then, roughly half an inch to one inch of rain has fallen at NWAC stations on Mt. Hood for the 48 hr period ending 4 am Saturday. Sunday and Monday have seen sunny weather and very warm temperatures, well into the 50's!

The Mt Hood Meadows patrol reported crusts and melt forms in the upper pack on Wednesday and Thursday with good stability. Some low density snow from the last storm was transported to N-NE slopes near and above treeline. Over the weekend, Meadows pro-patrol reported a saturated upper snowpack, but little in the way of avalanche action.  

The lower snow pack at Mt Hood should also predominately consist of crusts and stabilized rounded grain or melt form layers from warm periods so far this winter.

Detailed Forecast

Cooler temperatures with clouds and a few light showers are expected Tuesday. Only very light amounts of precipitation are expected, if any, and this should not change the overall low danger.

Generally avoid steep slopes, especially near terrain traps where you might be able to push off enough wet snow to start an avalanche large enough to take you for a ride.

Remember, due to the unseasonably low snowpack especially at lower elevations, numerous terrain hazards such as open creeks, partially covered rocks and vegetation are widespread.
