A prescribed burn intended to reduce wildfire risk in Yolo County escaped its containment lines on Monday and grew into a fast-moving blaze, forcing authorities to issue an evacuation advisory west of the city of Winters. By the evening the fire had spread to more than 360 acres and was only 15 percent contained.
Fire officials confirmed that the blaze had begun as a controlled burn carried out by Cal Fire earlier in the day, around 11:30 in the morning. Crews across the region had been clearing dry brush in anticipation of red flag warnings, but strong winds pushed the flames beyond the containment line and turned a preventive measure into an active wildfire.
Once it became clear the flames were no longer under control, Cal Fire shifted its operation to full wildland fire suppression. Crews attacked the blaze from the air and on the ground, using aerial drops and bulldozers as the fire moved uphill through light, flashy fuels that allowed it to spread quickly across the landscape.
The evacuation advisory was issued for areas west of Winters, with officials urging anyone who might need extra time to leave, as well as people with pets or livestock, to go now rather than wait. The town of Winters itself was not included in the advisory, but roads in the affected area were set to be closed overnight.
For the moment, no buildings were reported to be threatened, but tensions remained high given how close the fire was burning. Winters lies just seven miles from the flames, near enough that residents were being told to stay ready to leave at short notice should conditions take a turn for the worse.
The smoke also began to take a toll on daily life. The city of Winters canceled all of its pool programming on Monday out of an abundance of caution because of poor air quality, as haze settled over the area and the wind carried smoke toward nearby communities through the afternoon.
Firefighters faced steep and rugged terrain along with the drifting smoke as they worked to build containment. Officials acknowledged that even carefully managed controlled burns are not foolproof, and that fire can be hard to contain when the wind shifts, a warning that landed as the region braced for an even hotter and windier stretch later in the week.
