Over the last 72 hours, mountain alpine weather has seen air temperatures swing from minus six to zero degrees A total of 30 centimeters has fallen with moderate south east wind.

Ski cutting on steep west aspect terrain at tree line was touchy and produced numerous small wind slab with crowns down 20-30 cm and propagating easily. Explosive testing produced one small avalanche at tree line on a west aspect in a protected area.

The island snow-pack began development early this month with western areas seeing a settled snow-pack of 3 meters and drier eastern areas 2 meters. During this past period numerous days of moderate to heavy snowfall followed by significant rain events and freezing levels rising above 2000 meters produced three significant rain crusts. Over the past 48 hours up-to 25 cm of new snow has fallen on this upper crust and is moderately reactive in specific terrain features. The crusts exist in the mid snow pack but only the upper crust is currently reactive to human triggers. Surface- New snow up-to 25 cm Upper- Numerous melt freeze crusts exist in the upper snow pack.
