Another ten-to-16 inches of snow is possible in the Washington Cascades between Friday and Saturday morning, and some areas in WesternWashington could see wet snow as low as 500 feet.

KING 5 Meteorologist Rich Marriott said a Puget Sound Convergence Zone could occur later Friday. That means showers will be most likely, and heaviest, in north King county and Snohomish county. Moderate to heavy rain showers are likely there, possibly mixed with ice pellets or even wet snow. In heavier showers, wet snow is possible as low as 500-to-1,000 feet. Latest Forecast

  • Stevens Pass: 21 inches
  • Snoqualmie Pass: 13 inches
  • White Pass: 14 inches
  • Crystal Mountain: 12 inches
