Seattle's first snow storm of the season is coming to an end but there's more snow to come, according to the forecast.

Delays in commute were widespread throughout the day as cars were sliding and several accidents temporarily closed down lanes. Starting around 9 a.m. this morning, two car crashes blocked Aurora Bridge and traffic was backed up for about two hours. As snow continued to fall, accidents and slippery conditions on Highway 520 and Highway 99 slowed traffic in the afternoon and Interstate 5 was in gridlock.

Middle schools and high schools in the Seattle School District were dismissed in the early afternoon and all extracurricular activities as well as parent-teacher conferences were canceled.

Another round of snow is moving into the Seattle area this evening, and another 2-5 inches of snow are possible. Wind gusts of up to 40 mph are also expected.

Winter Storm Warnings remain in effect for Western Washington, including the greater Seattle Metro area until 10 p.m. tonight.

Travelers should expect low visibility and potentially slick roads.

The high winds can potentially knock down trees or power lines so residents are advised to have emergency supplies at hand in case of a power outage.
