San Diegans who strive to be prepared for wildfires can use a new Cal Fire mobile-device application to keep up with their readiness efforts, the state agency announced Friday. The free Ready for Wildfire app provides users with step-by-step checklists, allowing them to track their progress while managing vegetation, protecting their homes with fire-resistant construction, assembling emergency supply kits, and creating family communication and evacuation plans, according to Cal Fire.
