The Russian regions of Irkutsk, Buryatia, Sakha and Krasnoyarsk have declared states of emergency as the smoke chokes cities downwind, according to the Associated Press. All smoke can be hazardous, especially for the young or elderly.

However, NASA scientists don’t believe the smoke will be traveling low enough in the U.S. to impact air quality.

AccuWeather Senior Meteorologist Bob Smerbeck said that a storm tracking from Russia across the Bering Sea and into Alaska had steered the smoke into the area.

“Smoke can still be an issue this weekend,” Smerbeck said.

“The smoke travels at such high altitudes that it’s unlikely to significantly impact air quality in the U.S., unless wind currents reach the surface,” Atmospheric Scientist Colin Seftor said. Seftor works at NASA’s Goddard Space Flight Center and has been tracking the smoke through its journey, according to the National Oceanic and Atmospheric Administration.

According to Russia’s Federal Forestry Agency, more than 2.7 million hectares (6,671,845 acres) of Siberian forest is currently ablaze across six different Siberian and Far East regions. It all adds up to about the size of Massachusetts.

Russian officials have stated that although the fires have not encroached upon populated areas, about 800 cities are blanketed in heavy smoke, including larger cities such as Noosibirk, Krasnoyarsk and Chita, the AP reported. It is suspected that some of these fires were started by lightning strikes.
