If you were on the highest mountain peaks of the Pacific Northwest this week you would need a yardstick to measure snowfall totals.

continues to propel numerous storm systems into the region, making for a wet, windy, and in some cases, snowy weather pattern. Although the elevation at which snow versus rain will fall is varying with each weather system, the summits of some of the highest peaks in the region such as Mount Rainier, Mount Hood and Mount Baker will see nothing but snow, piling up foot-by-foot.
The Sunday night predicted that up to 190 inches (15.8 feet) of snow would fall at an elevation of 12,762 feet from Sunday night through Wednesday night. The low end of the forecast range from the NWS was still an impressive 152 inches (12.6 feet). For reference, Mount Rainier's peak elevation rises to.

Looking a bit closer at the details reveals why so much snow is expected in the 84-hour forecast. Mount Rainier was forecast to see about three feet of snow in three separate 12-hour forecast periods, including 32-38 inches on Monday, 33-39 inches on Tuesday, and 33-39 inches again Tuesday night.
To be clear, no one lives near the summit of Mount Rainier, so we'll never know for sure how much snow actually falls there. However, it does give an idea of how moisture laden the current weather pattern is for the Pacific Northwest, .
For perspective on how huge a 190-inch snowfall total would be, consider these facts:
- The snowiest season on record in snowy Syracuse, N.Y., yielded 192.1 inches of snow in 1992-93.- All but 14 inches of an average adult male giraffe (204 inches ) would be buried by the snow.-The minimum clearance for an interstate overpass in rural areas is 16 feet. A 190-inch snow depth would cover the highway up to within about two inches of the bottom of the overpass.

Mount Rainier and the other mountainous areas along the West Coast are no stranger to snowstorms dumping multiple feet of snow at a time, resulting in some large seasonal totals.
Take the Paradise area at Mount Rainier which is at a considerably lower altitude below Mount Rainier's peak at 5,400 feet. Despite its much lower altitude compared to the summit, of snow each season. In fact, it once held the world record for the most snow in a single season, which was 1,122 inches (93.5 feet) in 1971-72.
