Authorities say a wind-whipped fire in Northern California’s Wine Country has burned 49 buildings and prompted evacuation orders for 2,000 people. The fire that began Wednesday night near Geyserville has grown 22,000 acres. It’s just 5% contained. Fire officials say 1,300 firefighters have been working through the night and hundreds more may join the battle Friday morning. The cause is under investigation but Pacific Gas & Electric says it had a transmission line problem in the area minutes before the fire was reported. PG&E had cut power to parts of 17 counties to prevent wind-related power line problems that might spark fires but said it didn’t de-energize the transmission line because wind speeds there didn’t call for it.
