In reply to jonnie3430:
Forecasted snow amounts overnight and tomorrow for 'Meggie are less than all other areas except Torridon, so there's expected to be less load on the snowpack. However, the 'Considerable' category, statistically, is when most people get involved in avalanches, so care definitely required!
Also keep in mind the wording of the international avalanche hazard scale for the 'Considerable' category:
"Medium to large sized natural avalanches possible. In locations indicated in the reports, human triggered avalanches are likely; the snowpack is poor to weakly bonded in these locations."
The SAIS avalanche forecast is based on a bespoke, hour-by-hour and micro-scale Met Office forecast for each of the 6 mountain areas covered. If the weather on the day actually turns out to be different by a relatively small degree, then the snow conditions and respective avalanche hazard can often be quite different to the forecasted category.
Experienced members of the winter climbing public ought to use the avalanche forecast as a guide and make adjustments to their 'mountain day', factoring in any changes in the weather. The less experienced are probably best advised to take the wording of the avalanche forecast at total face value.
There is a developing buried weak layer issue at 'Meggie at the moment and we may see this playing a bigger part in stability issues if it stays cold and we get significantly more snow (loading).
