Recent Avalanche Activity

Recent Avalanche Activity
A few wet slides early last weekend in the rain.
After yesterdays snowfall a control run produced no results and nothing new has been seen.

Current Snowpack Conditions

Current Snowpack Conditions
Mostly well settled and stable. In some higher elevation locations up close to the main divide freshly fallen or wind drifted snow may lie over a weak old surface layer to create a chance of slab avalanching. This is only at present likely to be a player in the north and west of the forecast area.
25cm of new snow fell Tuesday at the ridgeline of Ohau Skifield. With the light winds all the reports are of great skiing/riding.

Mountain Weather

Mountain Weather
