Putah Fire Update: Containment Efforts Progress Amidst Red Flag Warning in California Wine Country

The Putah Fire, located in steep and rugged terrain near Lake Berryessa and the eastern edge of California Wine Country, quickly escalated after its origins in a Cal Fire prescribed burn. Initial reports indicated the fire grew from 361-362 acres on Monday to 860-869 acres by Wednesday. Cal Fire’s acknowledgment of full responsibility underscores the inherent risks and complexities of prescribed fire operations, which are crucial for reducing hazardous fuels and improving community resilience to wildfires. The agency stated that while the burn was initially conducted within approved parameters, unexpected wind shifts led to the escape.

Firefighting efforts involve a substantial deployment of resources, with approximately 285 personnel, including 15 fire engines, 12 hand crews, four bulldozers, and eight water tenders, actively working to strengthen containment lines. Air support from helicopters dropping water and air tankers deploying fire retardant has been critical in slowing the fire's spread in difficult-to-access areas.

The primary concern for firefighters and residents alike is the prevailing dangerous fire weather. The National Weather Service issued a Red Flag Warning from Wednesday night through Thursday morning for inland portions of the North Bay, including eastern Sonoma and Napa counties. This warning signals critical conditions for rapid fire growth due to high winds (expected gusts of 35-40 mph, with isolated ridge-top gusts exceeding 60 mph) and extremely low overnight humidity levels (10-20%). Furthermore, temperatures are forecast to remain well above normal, reaching the low to mid-90s in areas like Santa Rosa, Napa, and Cloverdale, further exacerbating fire risks.

In response to the elevated wildfire risk, Pacific Gas and Electric Co. (PG&E) has initiated Public Safety Power Shutoffs (PSPS) across parts of Northern California, affecting counties such as Colusa, Glenn, Lake, Sutter, Tehama, and Yolo. Portions of Napa, Solano, and Sonoma counties also remain under a watch for potential outages, impacting thousands of homes and businesses and requiring residents to prepare for power disruptions.

What caused the Putah Fire?

The Putah Fire originated from an escaped prescribed burn managed by Cal Fire. Unexpected wind conditions caused the fire to spread beyond control lines.

Is Highway 128 still closed due to the fire?

No, Highway 128 reopened in both directions on Tuesday night, June 9, 2026.

What are Public Safety Power Shutoffs (PSPS) and how do they relate to the Putah Fire?

PSPS are preemptive power shutdowns by utility companies like PG&E to prevent wildfires in high-risk weather conditions. Due to the dangerous fire weather associated with the Putah Fire and surrounding areas, PSPS have been implemented or are being considered across several Northern California counties to mitigate the risk of new ignitions or fire spread from power infrastructure.

The Putah Fire highlights the delicate balance between proactive wildfire management and the unpredictable nature of weather. What are your thoughts on the use of prescribed burns in high-risk areas?
