Wildfire scorches almost 7,000 acres in northern California
(CNN)A northern California wildfire continued to rage Friday, threatening homes and torching 6,900 acres in Napa and Sonoma Counties, authorities said.
The two-day-old fire roared so fiercely that satellite imagery captured its fiery footprint near Lake Berryessa, the National Weather Service said.
Napa and Sonoma Counties are part of California's wine country, but one Napa operator of wine tours said the fire posed no threats to vineyards on their tour.
"Our thoughts are with the families impacted by the Wragg Fire near Lake Berryessa, which is an hour's drive from our station," the Napa Valley Wine Train said on its Facebook page. The business offers a three-hour tour aboard an antique train through famous vineyards.
"Wine Train operations will continue as scheduled, unaffected by the fire," the firm said.
