An ozone advisory has been issued for parts of Riverside County through Thursday as a heat wave affects the region, officials said Monday.
According to the South Coast Air Quality Management District, the advisory began at 2:30 p.m. Monday and will remain in effect until 8 p.m. Thursday.
Air quality index will likely reach “unhealthy for sensitive groups” or higher for Lake Elsinore, Corona, Hemet and the Coachella Valley, according to the agency.
Officials said a multi-day extreme smog event was expected due to high temperatures.
The agency said it would provide an update if ozone levels maintained their high levels after the advisory expires.
