In reply to Suncream:
Print yourself out blank SAIS avalanche forecast roses. Check the weather forecast each day, particularly wind direction, wind variability, precipitation and freezing level and then colour in the Rose trying to predict the likely avalanche condition for the areas that SAIS operate. Do this throughout the season, or at least for the week before.
Compare to the actual SAIS forecast each day and try and understand / learn when there are differences.
You will get to a point of being very close to the actual ground observers forecast from the comfort of your home, and be far more aware than if you just rely on the published forecast.
Other than that always question if your plan is at odds with simple principles; stay out of gullies after/during heavy snow or during heavy rain, ditto for accumulation slopes, avoid climbing or lingering under cornices in thaw, climb with the wind to your back unless you are on buttresses (but consider the approach), think about your descent options as much as your climb, be suspicious of snow in sheltered gully tops, corrie rims and hollows, and there is no shame in taking a longer walk out in the dark if you don't like the descent slope.
