Forecasted Smoke and Air Quality Impacts

• Smoke from the Line Fire is expected to impact parts of the San Bernardino Mountains, where the AQI category may reach Very Unhealthy or higher, with the highest AQI immediately adjacent to the Bear Creek and Santa Ana River drainages.
• Light winds from the northeast will push smoke further into the South Coast Air Basin on Tuesday.
• Afternoon and evening AQI levels in parts of San Bernardino County will also be elevated due to ozone (smog) formation over the next few days.

If you are in an area impacted by smoke:

• Limit your exposure by remaining indoors with windows and doors closed or seeking alternate shelter.
• Avoid 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.
• Avoid burning wood in your fireplace or firepit and minimize sources of indoor air pollution such as candles, incense, pan-frying, and grilling.
• If you must be outside, a properly fit N95 or P100 respirator may provide some protection.
