Five thousand people in California's Napa Valley wine growing area have been ordered to evacuate their homes or told to prepare to, amid rapidly-spreading wildfires which have destroyed at least one winery.
Chateau Boswell, a 40-year-old family-run winery near St Helena was on fire on Sunday night, as firefighters desperately tried to put out the blaze.
Napa County Office of Emergency Services said 64 wineries sit within the evacuation or evacuation warning areas, along with rural estates and remote, unincorporated communities.
High winds, gusting at 55mph, were hampering attempts to put out the Glass Fire, which broke out at 3:50am on Sunday and has so far burned 2,500 acres near St. Helena.
St. Helena, around 15 miles north of Napa, has been the site of prized wineries since the 1860s. The area is home to Beringer, one of California's oldest continuously operating wineries, founded by Jacob Beringer and his brother Frederick in 1875. Some wines produced in the region sell for more than $460 a bottle.

The area is also flanked by the LNU Lightning Complex, which was sparked on August 17 and has destroyed 363,000 acres. It is now 98 per cent contained - unlike the Glass Fire, which is entirely uncontained.
County emergency management officials say 743 homes and 1,857 people are within the Glass Fire evacuation zone, the Press Democrat reported.
A further 1,370 homes and 3,425 people are in the larger evacuation warning zone.
