A brush fire on U.S. Marine Corps base Camp Pendleton forced some evacuations of military members and sent smoke across North County San Diego, prompting an advisory Tuesday. The Pipeline Fire started at about 2:10 p.m. Monday and had grown to 1,065 acres by Tuesday morning. A The fire appear ed to be in an area of the base that is mostly grassland but the blaze burned quickly enough that an evacuation order was issued Monday for an on-base area called 32 Area. The order remained in place Tuesday, according to base officials. An evacuation shelter was put in place at Paige Field House, which is on the military base. It was not immediately clear how many individuals and buildings were affected by the order. No off-base areas were under evacuation alerts. North County communities were also under a smoke advisory after winds carried the smoke over to the east and northeast of the fire, the San Diego County Air Pollution Control District said. Affected communities include Fallbrook, Pala, Valley Center and Oceanside. Overnight winds pushed smoke southward into foothill communities, including Ramona and Alpine. However, strengthening onshore winds were expected to reverse the smoke’s path by Tuesday afternoon, driving it back toward Fallbrook, Pala and Valley Center, according to the San Diego County Air Pollution Control District. As wind patterns shift, air quality was expected to improve in southern foothill towns like Alpine during the day, while conditions in northern communities such as Valley Center were likely to deteriorate, district officials reported. Health officials warned that air quality in areas with heavy smoke should be considered unhealthy for all individuals. In areas experiencing only minor smoke impacts, air quality levels range from moderate to unhealthy for sensitive groups. Authorities advised anyone who can smell smoke to limit physical exertion and outdoor activities. Residents were urged to stay indoors when possible to reduce exposure to fine particulate matter and ozone. These precautions are especially critical for children, the elderly and those with respiratory or heart diseases, officials said. Camp Pendleton fire officials were the responding agency with Cal Fire and Heartland Fire Rescue assisting with firefighting efforts. City News Service contributed to this report.
