SDG&E Weather Awareness System
San Diego Gas & Electric operates one of the most extensive weather monitoring networks in the country, specifically designed to track wildfire-relevant conditions across San Diego County — including San Elijo Hills and San Marcos.
The SDG&E Weather Awareness System provides real-time data on wind speed, humidity, and temperature at weather stations throughout the region. During high fire-risk periods, SDG&E may implement Public Safety Power Shutoffs (PSPS) — monitor their outage map for your neighborhood.

A Red Flag Warning is issued by the National Weather Service when weather conditions are ideal for wildfire ignition and rapid spread: sustained winds above 25 mph, relative humidity below 15%, and dry fuel conditions. San Elijo Hills is particularly vulnerable during Santa Ana wind events, which typically occur October through April.
During any Red Flag Warning: review your evacuation plan, charge devices, top off your vehicle with fuel, and have your go-bag ready.
