Blowing Snow by the Lake Causes Crash

Take 4 inches of light powdery snow a 375 acre lake and winds gusting to 40 mph and you have a scene out of the show "Highway to Hell". Snow drifting 1-2ft on RT # 46 with white out conditions. While operating at the MVA if you went to the rig for equipment you had to wait for the snow to stop blowing so you could see the cars.
