Narrative:
40 miles from our destination at 12000 feet in descent received avionics smoke alarm. Declared emergency and landed runway 06R. Avionics smoke alarm activated in my opinion due to water/melted snow that entered aircraft while on ground loading at flight origin.the ground crew did a good job of removing snow off the cans but in blizzard conditions with high winds and blowing snow it is near impossible to keep all snow out of the aircraft.
