NWS Forecast Office Los Angeles, CA

Wildfire activity over the region has led to smoky skies for much of Southwest Califorina, especially for areas near the Bobcat fire north of Arcadia. The smoky conditions are expected to continue through Friday, and should improve over the weekend. Use common sense to assess the air quality, if you smell smoke or it looks smoky outside, limit your time outdoors. Also check your local air quality at AirNow.gov. Air quality is more likely to be poor near a wildfire, and keep in mind that air quality can fluctuate hour by hour. Breathing in smoke can aggravate lung disease, cause asthma attacks, cause acute bronchitis, and increase the risk of respiratory infections. Avoid prolonged exposure, especially for sensitive populations such as children, elderly, and people with respiratory or heart disease. Avoid strenuous activities and keep up to date on conditions so you can seek shelter if conditions worsen.
