Rain then Snow on the Tops



The snowpack has depleted in the thaw, but temperatures dropped in the afternoon and it should all re-freeze. New snow with strong winds will produce some tricky avalanche conditions for the next day or so !

Ski Tourer heading into Coire Lochain
The snowcover is good - some hellish crust which gets firmer and stronger the higher you get. Pretty icy on steep ground with some serious runouts !! Conditions looking good for climbing.

Heavy snowfall and drifting

Difficult walking conditions in the strong winds
Significant snowfall over the past 24 hours has led to heavy drifting and poor visibility

Bad Weather Thursday

Saturdays Avalanche debris

The Debris

This is on the East side of  Fiacaill a Choire Chais ridge.  Windslab was rapidly building on this slope yesterday, a large crack developed at around midday and the slope was trigger by a skier not long afterwards.  Crown wall is a metre in height, stretching to around 150m  in length
Great conditions in the Cairngorms
Good cover on the plateau, a mix of boiler plate and wind slab

Good snow cover for all travel modes and good climbing too - All change tomorrow with storm force winds and heavy snow above 700 metres.

Windy and Wet

A day of strong winds on the tops - but  rain also at all levels - good snowcover throughout the area even though it is a thin cover.
The snowpack has moistened and so will refreeze as it gets colder from Sunday and into next week. This should create some good climbing conditions and firm up the snowpack even further.
