Southern California Edison has divided Los Angeles County into High Fire Risk Zones based on vegetation density, historical fire patterns, and transmission line exposure. During Santa Ana wind events, when gusts exceed 40 miles per hour and relative humidity drops below 10 percent, the utility implements Public Safety Power Shutoffs that can affect over 100,000 customers across LA County. These shutoffs target areas near the Angeles National Forest, Topanga State Park, and other wildland-urban interface zones where power lines pose ignition risks. Residents in these zones lose power for 48 to 96 hours while crews patrol lines and verify safe conditions. Whole house generator services provide the only reliable solution for maintaining power during these increasingly frequent preventative outages. Your home remains powered regardless of utility company risk mitigation strategies.
