The Pickett Fire, a fast-growing wildfire near Calistoga in Napa County, California, erupted on August 21, 2025, and has since expanded rapidly, burning over 3,200 acres as of August 23. Initially reported at approximately 15 acres with zero containment, the fire quickly grew to more than 1,000 acres by the evening of August 21 and nearly doubled overnight to over 2,100 acres by August 22 afternoon. By late August 22, containment remained low at 5%, increasing slightly to 7% by August 23. The fire is burning in dry, remote, and rugged terrain, complicating firefighting efforts. Evacuation orders and warnings have been issued for multiple zones around Calistoga, including areas north and south of Silverado Trail, Pickett Road, and surrounding rural regions. The Calistoga Community Center has been opened as an evacuation shelter. Several prominent Napa Valley wineries fall within the evacuation zones. Fire officials have noted the potential for significant fire growth due to hot, dry, and windy conditions with low humidity affecting much of the Western U.S. The fire has not directly threatened Napa towns but has impacted air quality in the region. Meanwhile, firefighters have also been battling the Parks Fire near Dublin and San Ramon, which has scorched about 117 acres with zero containment as of August 23, though forward progress has been stopped. Both fires present challenges due to heat, smoke, and difficult terrain.
