Detailed Forecast

Mt Hood Forecast

An occluded front should move south to north over the Northwest Wednesday night and Thursday. South to southeast alpine winds Thursday morning should generally shift to southwest Thursday by afternoon.At Mt Hood look for moderate to heavy amounts of snow by later Thursday.

Watch likely new wind slab on lee slopes and new storm slab in calmer less exposed areas. Remember that the avalanche danger will be greater if you encounter stronger winds and heavier snowfall. Evaluate snow and terrain carefully Thursday. Change your plans if you find yourself in unexpectedly prolonged stormy weather.

Less snow below tree line should limit the avalanche danger there.

Snowpack Discussion

Mt Hood Weather:

Snowfall at Mt Hood the first 7 days of December was about 1.5-2 feet with an overall warming trend. Then an atmospheric river arrived the past couple days (Main Fork of the Pineapple Express) and heavy rain with about 5-7 inches at NWAC stations in just 2 days ending this morning. Wow!

But snowfall has resumed on Wednesday with a cooling trend. Good news!

Mt Hood Snowpack and Reports:

The Mt Hood Pro Patrol on Wednesday reports a greatly consolidated and stabilized snowpack. Small new wind and soft slab was beginning to form on Wednesday afternoon.
