The Pickett Fire in Napa County, California, has become a significant concern as it continues to grow, threatening numerous wineries and prompting widespread evacuations. Over the weekend, the fire burned nearly 4,000 acres, exacerbated by a relentless heatwave affecting the US West. Residents have received evacuation orders, especially around Calistoga, as firefighters strive to gain control of the blaze, which remains largely uncontained. Air quality has also deteriorated in the region due to smoke from the fire, raising health concerns. Fire crews are working diligently to combat the situation in steep terrain, aiming to protect both communities and vital vineyards in this renowned wine country.
