The National Weather Service issued a Winter Weather Advisory on Tuesday for Pullman and surrounding areas on the Palouse, including Moscow and Colfax.  

The advisory is in effect until 4 a.m. Wednesday morning. Predicted conditions include snow accumulation of up to three inches and wind gusts of up to 40 mph. 

The National Weather Service predicts that Pullman will reach a low of 19 degrees early Wednesday morning, though the wind chill will make it feel like single-digit temperatures. 

The weather may cause hazardous conditions Tuesday evening. Slick, dangerous roads are likely, and slow, cautious driving is advised, the National Weather Service said. 

There is also a risk of flash freezes due to the snowfall and freezing temperatures, the National Weather Service said. 

Flash freezes are a sneaky winter hazard, the National Weather Service said. Flash freezes occur when there is a rapid drop in temperature. They are especially dangerous when paired with precipitation on the ground.

In the event of a flash freeze on the road, the National Weather Service said that people should drive slowly, leave distance between the car in front of them, and avoid using cruise control. Flash freezes are likely if the road appears wet during freezing temperatures. 

The National Weather Service urges people to use caution when traveling outside. 

For current road conditions, the National Weather Service said to call 511 to reach the Washington State Department of Transportation. 

Pullman PD Operations Commander Aaron Breshears said that the department does not have plans to take extra steps for this weather advisory, since winds already reached a peak of up to 60 mph early Tuesday morning.

“We’re not planning on taking any extraordinary steps for the wind alone, but we will be responding to emergency calls or calls for service where weather has caused problems for the public,” Breshears said.

He also said that people should have supplies prepared in their vehicle in case of emergency.

“We always encourage everyone to plan ahead when traveling and to make sure they have the proper safety equipment for their vehicles including snow tires, chains, and emergency weather equipment within their vehicles when they are traveling, such as blankets and extra coats,” he said. “Always make sure you clean your windows before you travel.”

The Winter Weather Advisory will remain in effect until 4 a.m. Wednesday.
