If the upper air winds of the jet stream pass through the more tropical latitudes of
the Pacific Ocean, say off of Hawaii, that warm air picks up as much moisture as its
temperature will allow. Often in the Fall, this warm, moist air pummels the entire
west coast as heavy rain. Later, as ski areas accumulate 3-4 storms worth of snow our winter
season starts, typically with 30 inches of snow base. By April, we may have had
30 or more storms and hundreds of inches of snow.
