The Washoe County Health District says smoke from the Rim Fire near Yosemite National Park is creating unhealthy conditions.

It released this message Friday morning:

Smoke from the wildfires in California is impacting the Truckee Meadows. We anticipate the smoke to impact the Reno/Sparks area today and through the weekend. The smoke is expected to create "Unhealthy for Sensitive Groups" and "Unhealthy" conditions meaning that people with respiratory or heart disease, the elderly and children should avoid prolonged exertion; everyone else should limit prolonged exertion. If the smoke is affecting you, remain indoors with the windows closed and air conditioning on and reduce any outdoor activity.
24 hour average:  157 Unhealthy (PM2.5)

Meanwhile, the Rim Fire grew overnight to more than three times the size of the city of San Francisco as it spread inside the border of Yosemite National Park.
The flames have also forced the evacuations of hundreds from homes. 
California Department of Forestry and Fire Protection spokesman Daniel Berlant said Friday the blaze had grown from 99 square miles to more than 165 square miles and was only 2% contained.
Berlant said the fire threatens about 4,500 residences.
While Yosemite remains open, the wildfire caused the closure of a 4-mile stretch of State Route 120, one of three entrances into Yosemite on the west side, devastating areas that rely on tourism.

In the next 24 hours, the fire is expected to continue up the Tuolumne River canyon, and continue its spread north and east.

The fire remains under investigation.
