Air Quality Much Improved but May Still Reach Unhealthful Levels in Areas of Active Wildfires
Although air quality and weather conditions have improved significantly
across the Southland, air quality may reach Unhealthy levels in areas directly
impacted by smoke from the Sayre and the Freeway/Triangle Complex fires.
In addition, areas farther from the active burning may still experience
periods of air quality in the Unhealthy for Sensitive Groups range, or higher,
when impacted by smoke.
All individuals are urged to exercise caution and avoid unnecessary
outdoor activities in any area directly impacted by smoke. This includes
areas where residents can see or smell smoke.
Depending on the fire situation, areas of direct smoke impacts will likely
include:
• the Corona/Norco area;
• the Chino/Chino Hills area;
• North Orange County;
• the Pomona/Walnut Valley;
• the San Fernando Valley;
• portions of the San Gabriel Mountains that are near the Sayre Fire; and
• portions of the Santa Clarita Valley.
In areas with Unhealthy for Sensitive Groups air quality, sensitive or
susceptible persons, such as those with heart or lung disease, should
minimize outdoor activity.
In areas with Unhealthy air quality and those directly impacted by
smoke: Everyone should avoid any vigorous outdoor or indoor exertion;
people with respiratory or heart disease, the elderly, and children should
remain indoors. Keep your windows and doors closed unless it is extremely
hot inside. In these cases, seek alternate shelter. Run your air conditioner if
you have one. Keep the fresh air intake closed and the filter clean to
prevent bringing additional smoke inside.
