Border 2 Fire Erupts Near U.S.-Mexico Border, Threatens Communication Infrastructure

The Border 2 Fire broke out on January 23, 2025, in the Otay Mountain Wilderness Area near the U.S.-Mexico border in San Diego County. Fueled by strong Santa Ana winds, low humidity, and dry vegetation, the fire quickly grew to 600 acres and remained uncontained. Over 200 personnel were deployed to combat the flames, which threatened critical communication infrastructure but no structures. The fire caused significant air quality issues, prompting a smoke advisory. The cause of the fire is under investigation, with unusual conditions for January noted due to prolonged drought. Rain is expected by Sunday, with no significant flooding or mudslide risks anticipated.
