A wildfire, known as the Rainbow 3 Fire, erupted in the Rainbow community northeast of San Diego, scorching dozens of acres in steep terrain and threatening nearby structures. It began near Rainbow Crest Road, with initial reports placing the fire at about 50 acres and a moderate rate of spread, aided by topography. Cal Fire deployed roughly 200 personnel, along with multiple engines, crews, air tankers, and water-dropping helicopters to fight the blaze. Evacuation alerts were issued, including Level 2 and Level 3 warnings for areas around Rainbow Crest, and a temporary shelter was opened at the Seventh Day Adventist Church in Fallbrook for the displaced. By mid-morning, crews reported progress toward controlling the fire, though conditions remained dynamic and the acreage stood around 50 acres. Authorities continue to monitor the situation and urge residents to stay alert for evolving evacuation instructions as the incident develops.
