Early Red Flag Warnings Signal Higher Wildfire Risk in Central Valley

California's wildfire season is starting early this year, with red flag warnings and above-normal fire activity already affecting the Central Valley, particularly in Tulare County and the foothills surrounding Visalia. The National Weather Service issued its first red flag warning in mid-May for Kern, Tulare, Fresno, and Merced counties, signaling that warm temperatures, very low humidity, and strong winds are creating dangerous conditions for fire ignition and rapid spread.

Dry grass and gusty winds are fueling fast-changing fire conditions in the rangelands and Sierra-facing slopes around Visalia, Porterville, and other communities. Fire officials warn that this year's danger is arriving earlier than usual as warm, dry weather accelerates the drying of fuels across the region.

Cal Fire, through its Wildfire Threat and Intelligence Integration Center (WFTIIC), continuously monitors NWS alerts and fuel conditions to prepare for the next red flag warning. Residents are urged to prepare well before any warning is issued.

David Acuña, a Cal Fire battalion chief and public information officer, emphasized that preparation should start long before any wind or fire threat. He recommends creating defensible space around homes, having a go-bag ready with essentials, and planning evacuation routes.

During a red flag warning, people should avoid activities that could spark a fire, such as mowing or using outdoor power equipment, welding, or any activity that could ignite dry grass. "We generally say mow before 10 a.m., but during a red flag warning, we say don't mow at all," Acuña said.

Common wildfire starts come from everyday activities, including campfires not fully extinguished, dragging trailer chains, and poorly maintained vehicles that can emit hot debris. Even a single spark can quickly grow into a dangerous fire under red flag conditions.

To track fires, evacuation orders, and road closures, Cal Fire's website provides real-time information on all fires over 10 acres in the state. Residents can also monitor local alerts and the California wildfire map for updates as conditions change.
