From SDAPCD: Due to the ship fire burning in San Diego harbor, localized areas of smoke have occurred in areas of San Diego County. As a result fine particulates, or PM2.5 concentrations, may reach unhealthful levels in some smoke impacted areas. In areas of heavy smoke, assume that air quality levels are unhealthy for sensitive groups to unhealthy for all individuals. In areas with minor smoke impacts, assume that air quality levels range from moderate to unhealthy for sensitive groups. In areas where you smell smoke it is advised that you limit physical activity. If possible, stay indoors to limit your exposure to fine particulate matter.
Report air quality issues by contacting the APCD at 858-586-2650, via e-mail at email@example.com, or via the Tell Us Now mobile app. For more information, visit https://www.sdapcd.org/

See also National Weather Service San Diego Facebook: If you are just waking up, you may notice a fairly acrid smoke smell if you live near San Diego. It’s likely related to the fire aboard USS Bonhomme Richard. The highest smoke concentrations (blue & yellow shades) will shift through the day as onshore breeze kicks in. The good news is that as temperatures rise, smoke should be able to better mix out vertically, reducing the near-surface concentrations somewhat.
