Yosemite National Park will close temporarily starting at 5 p.m. Thursday and will likely remain closed through the weekend because of smoky skies and hazardous air quality, according to a park statement.
Because of smoke from nearby fires, the air over the park will be in the “unhealthy to hazardous range over the next several days,” the statement said.
Airnow.gov showed a 681 pollution score for air in Yosemite Valley; hazardous air scores at 301 and above, with a scale starting at zero. The higher the air-quality index number, the more polluted the air. People breathing hazardous air should stay inside and avoid activity.
The biggest fire near Yosemite is the Creek fire, which started Sept. 4 and had grown to 244,756 acres as of Thursday afternoon. It’s burning in the Sierra south of Yosemite. Also, two small lightning fires are burning in the southern part of the park.
