Smoke from the Sesnon and Marek fires continue to affect the San Fernando, Simi and Santa Clarita Valleys, including the immediate areas around fire scorched San Gabriel Mountains. However, the South Coast Air Quality Management District adds a new warning today with the changing winds: "As the winds diminish and shift, additional areas may experience smoke and ash, causing air quality to be Unhealthy for Sensitive Groups or higher." Basically, continue to keep those windows shut and avoid vigorous outdoor or indoor exertion, they say. LA County's Dept. of Public Health recommends that "all individuals wanting to pursue any outdoor activities in areas where smoke, soot, or ash can be seen or there is an odor of smoke" should be avoided.
