Southern California'south legendary Santa Ana winds wreak havoc every year, creating hot, dry out conditions and burn down hazards.

Public Safety Power Shutoff (PSPS)

To find out if you are impacted, refer to the SCE'due south PSPS website. SCE customers tin can also sign up for outage alerts.

Santa Ana Wildfire Threat Index

The Santa Ana Wildfire Threat Index (SAWTI), produced by USDA Forest Service and Predictive Services, categorizes Santa Ana winds based on anticipated burn potential. The index uses a comprehensive, state of-the-fine art predictive model to create a detailed daily assessment of the fuel weather across Southern California. This information is coupled with calibrated weather condition model output (comprised of wind speed and atmospheric moisture), to generate a 6-twenty-four hour period forecast of Large Burn Potential. The Large Fire Potential output is then compared to climatological data and historical fire occurrence to establish the index rating. There are iv threat zones monitored: Zone 1: Los Angeles-Ventura; Zone ii: Orange-Inland Empire; Zone 3: San Diego; Zone 4: Santa Barbara. The Threat Index includes iv nomenclature levels from "Marginal" to "Farthermost."

The National Weather condition Service can also be monitored for Santa Ana Wind and burn down forecasts.
