The South Coast Air Quality Management District issued a windblown dust advisory Monday for parts of Riverside County through Tuesday morning.
The advisory will remain in effect until 10 a.m. Tuesday, the agency said. Periods of elevated particle pollution levels were expected in Jurupa Valley, Riverside, Corona, Perris and surrounding areas Monday and Tuesday.
“High Santa Ana winds have led to poor air quality throughout the Long Beach area, Orange County and the Inland Empire since early Monday morning,” the agency said.
Air quality index levels are expected to be very unhealthy or worse as a result of blowing dust, the SCAQMD said.
The agency advised people to limit their exposure by remaining indoors with windows and doors closed and avoiding vigorous physical activity.
“Run your air conditioning and/or an air purifier. If possible, do not use swamp coolers or whole house fans that bring in outside air,” the group advised.
The SCAQMD is the regulatory agency responsible for improving air quality for large areas of Los Angeles, Orange, Riverside and San Bernardino counties.
