Unseasonably cold weather for late February is causing the snow level to fall to the lower elevations of the Cascade Foothills and Coast Range of Southwest Washington and Northwest Oregon today. As much colder air moves into the region Wednesday and Thursday, accumulating snow will become likely down to the beaches and valley floor later Wednesday through Thursday.
- Some light accumulating snow will be possible in the higher elevations early tomorrow morning with heavier snow beginning later Wednesday and continuing into Thursday.
- A trace, up to three inches of snow is possible early Wednesday morning in the higher terrain.
- General storm totals of two to five inches are expected for the coast and lowlands by Thursday evening. Some local accumulations of six to 10 inches is possible mainly in the higher hills.
- Roadways may become icy and snow covered resulting in slick driving conditions. This may significantly impact the commute both Wednesday and Thursday.
A winter storm warning for heavy snow means severe winter weather conditions are expected or occurring. Significant amounts of snow are forecast that will make travel dangerous. Only travel in an emergency. If you must travel keep an extra flashlight, food, and water in your vehicle in case of an emergency.
