Keep dry. Don't so burden yourself with clothesthat you perspire and get wet from the inside (this iseasy to do). Keep the pack waterproof. Chances are itwill be heavy enough without being soaked.
Don't go hungry. Food is a source of necessaryheat. Too often the discomfort of stopping to eat in astorm is apt to result in the skier's eating too little. Relyon quick-energy foods that can be eaten quickly, and eatthem frequently, on the trail if you prefer not to stop.A simple rule is, eat sugar for energy, protein for heat.
Ski slowly and cautiously. At best visibility is somuch poorer during storm, as well as in some storm-bred flat light conditions, that it is most difficult to determine snow texture and topography well enough in advance to permit speedy travel. Any accident is doubly serious during storm. Don't protect the eyes so adequately that you in effect blindfold yourself; better, slow down, lower the head, and look through the eyelashes.
