South Coast Air Quality Management District: Smoke Advisory

Issued Tuesday, October 10, 2017

This advisory is in effect through Wednesday morning.  SCAQMD will issue an update if additional information becomes available.

A brush fire, named the Canyon Fire 2, is burning in Orange County near Gypsum Canyon, Anaheim Hills and towards the cities of Tustin and Orange.  The burn area is reported to be 7,500 acres this morning, with 5 percent containment.  Smoke is currently heavy in the vicinity.  Breezy winds from the east will transition to a sea breeze from the southwest starting around 11 a.m.  Smoke and ash impacts will be greatest in the vicinity of the fire and downwind into portions of Orange County this morning and likely into Riverside County this afternoon, depending on evolving fire conditions.  Air quality may reach Unhealthy levels or higher in areas directly impacted by smoke.

Ares of direct smoke impacts and Unhealthy air quality include portions of:SCAQMD

  • North Orange County (Forecast Area 16)
  • Central Orange County (Forecast Area 17)
  • North Orange County Coast (Forecast Area 18)
  • Saddleback Valley (Forecast Area 19)
  • Central Orange County Coast (Forecast Area 20); and
  • Corona/Norco Area - Riverside County (Forecast Area 22).

In any area impacted by smoke: Everyone should avoid any vigorous outdoor or indoor exertion; people with respiratory or heart disease, older adults, and children should remain indoors. Keep windows and doors closed or seek alternate shelter. Run your air conditioner if you have one and keep the fresh air intake closed and the filter clean to prevent bringing additional smoke inside. Avoid using a swamp cooler or whole-house fan to prevent bringing additional smoke inside. To avoid worsening the health effects of smoke, don’t use indoor or outdoor wood-burning appliances, including fireplaces.
