Russia Wildfire Smoke Reaches California, Oregon and Washington (published by www.weather.com 20 April 2015)
Smoke from wildfires thousands of miles away in Russia reached the U.S. West Coast this past weekend (April 17-19).
Strong winds fanned agricultural fires in Siberia on April 12 that eventually got out of control. At least 23 people were killed and more than 1,000 homes were damaged or destroyed in southern Siberia.
In the first three images above you can see how satellites sensed the aerosols associated with the smoke as winds aloft transported them from eastern Russia to the north Pacific Ocean April 15-17. The blue, green, yellow and orange shadings illustrate where the aerosols were concentrated each day as they spread east.
The smoke reached Washington on April 17, as shown by the hazy conditions in the fifth image. Hazy skies were observed by residents of western Washington that day, as the National Weather Service in Seattle noted in this tweet.
Smoke from the Russian fires then spread southward near and either side of the Oregon and northern California coasts April 18-19. The smoke was clearly visible on satellite both days.

Russian farmers routinely set fire to dry grass to clean fields after the winter, sometimes accidentally sparking blazes that result in loss of life and damage to homes. During the first weeks of April 2015, grassfires have ravaged across the Siberian regions of Russia, killing 26 people and injuring almos a thousand. The combination of temperatures reaching 25°C and high winds have fueled the fires that have destroyed buildings and killed livestock. In 2010, during Russias worst heatwave in decades, smoke from wildfires and burning peat bogs in central Russia choked Moscow for several days.
