The San Diego County Pollution Control District issued a smoke advisory Sunday, saying air quality levels were unhealthy in areas of heavy smoke.

“Due to the Valley Fire burning near Alpine in San Diego County, areas of smoke are affecting parts of the county,” district officials said. “The smoke continues to disperse above ground level away from the immediate area of the fire and is generally blowing toward the west-northwest as of Sunday afternoon. Smoke impacts are likely in areas near the fire, where fine particulates may reach unhealthful levels.

“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.”

Meteorological conditions were expected to improve air quality and shift the trajectory of the smoke toward the east and northeast on Monday, pollution control officials said.

“In areas where you smell smoke it is advised that you limit physical and outdoor activity,” officials said. “If possible, stay indoors to limit your exposure to fine particulate matter and ozone, especially those residents with respiratory or heart disease, the elderly, and children.”
