As a potent storm drops into the Northwest Friday from the Gulf of Alaska, a Winter Storm Warning is in effect from Friday morning through Saturday morning for all Cascade passes.
Snow will develop Friday morning, and become heavy at times Friday afternoon -- even at Snoqualmie Pass -- where snowfall rates are expected to reach as high as 1 inch per hour.
Overall snow totals are forecast to range between 12-18 inches by Saturday morning, with maybe 2 feet of snow around Mt. Rainier.
Snow will taper off as Saturday morning progresses.
