Thanks for posting this, its a good learning point for people like me who are inexperienced in winter conditions. Here is the SAIS report

Northern Cairngorms

Considerable - Natural avalanches may occur, in some cases large, in isolated cases very large are possible. A single person load is likely to trigger an avalanche on some steep slopes. Good hazard evaluation, visibility and route selection important especially in steep locations as indicated. Careful group management and good spacing is vital. Use mountain features (ridges and scoured slopes etc) to travel safely.

I think that's for the period Wednesday to Thursday if it was published on the 6th. The one for Tuesday through Wednesday (published on the 5th) is here: https://www.sais.gov.uk/northern-cairngorms/?report_id=11253. You can find historical forecasts here: https://www.sais.gov.uk/forecast-archive/. It was still considerable for the relevant aspects for Central Gully though.

Interesting video on the Cairngorm MRT instagram account of some of the rescue as well.

Sais have a video on their instagram describing the recent snow pack it's very informative
