Winter storm warnings and weather advisories are in place across northern Washington as another round of heavy snow is expected for the Cascades and Olympics. The Olympics are forecast to receive 8-18 inches by tomorrow morning while the Cascades could see as much as three feet by Friday morning. In addition to the snowfall hazard, avalanche warnings are in effect for the same mountain ranges. Strong winds and gradual warming will lead to the possibility of avalanches in the mountains. I will admit I am not as familiar with the avalanche phenomenon, but I am aware of their power. It’s probably not the best time to hike in the mountains of Washington.
Meanwhile, as you can probably see from the map, winter storm watches are in effect for the Sierra Mountains. The storm system bringing snow to the Cascades is expected to bring snow to California on Friday. Right now, the forecast does not call for snowfall totals to be as high as those seen in Washington. Still, a foot or so of snow cannot be ruled out in the highest elevations.
