YAKIMA, Wash. — The season’s first snow dusted the lowlands of the Yakima Valley today.

The Yakima airport reported a light coating of snow, with flakes also descending on Naches, Cowiche and Terrace Heights.

Light snow is falling on White Pass. The roadway is a bit slushy, and snow is sticking to the shoulder, said Mike Westbay, a spokesman for the state Department of Transportation.

Snow plows are ready to roll if needed, he said. Stevens and Chinook already have their first snow — up to a few inches — from the cold spell that passed through a couple of weeks ago.

The snow level ranges from 500 to 1,500 feet for the Yakima Valley through tonight, according to the National Weather Service.

Tonight’s low temperature is forecast at 33 degrees.

The next week should be warmer. Highs will be between 55 and 65 degrees, with nighttime lows in the mid-30s or above, weather service meteorologist Robert Cramp said from the agency’s office in Pendleton, Ore.

While the first major snowfall is not expected until about the first of November, drivers should prepare now for the winter driving season.

Studded tires become legal Nov. 1. Drivers should also stock their cars with blankets, food, a shovel and other emergency supplies.

Westbay said motorists should drive carefully whenever the roadway could be slick. Slowing down, braking carefully and avoiding use of cruise control helps reduce the chance of a crash, he said.
