Setting aside the weather hazard and potential fall hazards it is a lot like moving at night. GPS is your friend if it works. If you need to go old school then terrain association is only as good as you visibility but you can get some sense (am I going up hill or downhill). Also techniques like hand railing, back stops and attack points become important with no visibility.
