The Washoe District Health Department has issued an air quality alert for the Truckee Meadows after ozone reached a level of unhealthy for sensitive groups.
The department recommends people, especially those with lung disease like asthma, reduce prolonged or heavy outdoor exertion.
Fine particulates were moderate early Sunday afternoon.
Pollution is coming into the area is from California fires, said Scott McGuire, a meteorologist with the National Weather Service.
“It’s a combination of the Sand Fire down by Amador and El Dorado counties and the El Portal Fire by Yosemite,” McGuire said.
There’s a chance it could continue into Monday as it appears the fires are growing, McGuire said. But he doesn’t think the area will experience anything like the two-week haze that choked the air last year due to the Rim Fire near Yosemite.
Moisture will move into the region beginning Tuesday, which may not only drop moisture on the fire but help clear the air of smoke through rain drops.
“It will be a fairly active week again with the moisture advecting from the south,” McGuire said. “It’s tough to tell exactly where the thunderstorms will set up.”
High temperatures in the Reno area will be in the mid 90s with overnight lows in the mid 60s, which is close to average, McGuire said.
This happens to be the hottest week of the year in Reno on average, he noted.
