The South Coast Air Quality Management District issued a windblown dust advisory Wednesday for parts of Riverside County through Thursday evening.
The advisory will remain in effect until 6 p.m. Thursday, the agency said. Periods of elevated particle pollution levels were expected in Jurupa Valley, Riverside and surrounding areas Wednesday and Thursday.
An earlier AQMD windblown dust advisory was set to conclude at 6 p.m. Wednesday. That advisory began at 6 p.m. Monday, with regulators saying the Coachella Valley and San Gorgonio Pass would be hit hardest.
“Periods of elevated particle pollution levels in the Coachella Valley and San Gorgonio Pass are expected from Tuesday evening through Wednesday evening,” 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.
