Wet slide activity will lessen today, Northern aspects is where we expect to still see activity. Any remaining loose snow will be transported to lee aspects. Wind-slab development will build. Be aware of the changing conditions.
Nth facing aspects will be the main areas of concern today. The steeper the terrain the more likely a loose wet avalanche will be initiated. Try and find a balance where you get softened snow without being pushed over a nasty drop. Still be on the lookout for rafting, roller balling and pinwheels. Cooler winds may see this become less of an issue as the day progresses. Maybe...
Wind-slab will be building today. Be careful in and around complex terrain. Polar (shady) aspects above 2000 m is where you will need extra care.
Reactive loose wet avalanches (size 1 to 2) reported below 2000m. As cloud rolled in during the afternoon, activity lessened. Mainly due to less direct sun input and slightly cooler temps.
A different day ahead, mainly due to the rising strength of gale force N winds. Yesterday wet slide activity was widespread, most aspects below 2000 m affected to some degree. Pockets of wind-slab may have survived on polar aspects above this elevation. A refreeze overnight, expect a breakable crust in places. We can expect more wet slide activity today, however limited to direct N facing aspects. Wet slides are powerful events and can entrench vast quantities of heavy snow. Watch steep sided gullies where one side has warmed more than the other. Pay particular attention to terrain traps.
A fine frosty morning. Cloud coming and going at times as the day progresses. Winds from the N will build to gale strength by afternoon. The freezing level at 1800 m.
Overnight frosts mean icy patches have returned. A sliding danger is possible. Lower elevations are places where extra care is required.
