Another winter storm caused big problems Tuesday for Western Washington and Cascades passes, where heavy snow fell through much of the day and forced the closure of Interstate 90 and US 2 - Stevens Pass for a time.
Both passes have since reopened.
I-90 at Snoqualmie Pass reopened in both directions at 10 p.m. from Easton to North Bend after the heavy snow and slushy roads caused spinouts earlier in the day. There are still minor backups and traction tires are required.
At Stevens Pass chains required on all vehicles except all wheel drive, oversize vehicles prohibited.
KING 5 Meteorologist Jim Guy says we could see 6-12 inches of more snow in the mountains overnight Tuesday and another 5-10 inches of accumulations during the day Wednesday.
Guy expects scattered showers and increasing rain later in the day Wednesday with temperatures in the mid 40s for the lowlands. Cooler air may produce some isolated thundershowers or ice pellet showers, mixed in with sunbreaks.
Heavier showers could bring mixed snow/rain or wet snow in some higher inland hills, such as Tiger, Cougar, Squak mountains and the Somerset area.
"One more system to get through tomorrow night into Thursday morning. Things will quiet down for the weekend," said Guy. Check the forecast
