This week, the Snoqualmie Valley will endure both unhealthy air quality and a heat advisory.

As wildfire smoke travels to western Washington from central and eastern Washington, the air quality has quickly deteriorated. As of Aug. 4 at 4 p.m., the Air Quality Index is at least 150 in all Valley cities, with some seeing an index of more than 160. AQI 150 is when officials recommend staying inside, regardless of risk level.

A heat advisory is in effect from 10 a.m. Wednesday to 10 p.m. Thursday, with temperatures towards 90 degrees Fahrenheit.
