Friday night's sunset had an orange tint, similar to what we see when wildfires are burning in Central or Eastern Washington.

The National Weather Service said the haze is most likely caused by smoke from fires in Siberia, with some dust from Asia mixed in.

Wind-whipped grassland fires set by Russian farmers preparing for spring planting have killed more than 20 people, injured more than 900 and left 5,000 homeless.

The fires swept through nearly 60 villages and destroyed or damaged more than hundreds of homes in the southeastern Siberian region of Khakassia.
