KTVU - The powerful winds that fanned the flames last Sunday, and helped ignite the Wine Country wildfires, returned overnight.
The San Francisco Bay Area National Weather Service reported that offshore winds were over the wildfires in Napa and Sonoma Counties.

Firefighters said they were starting to make progress on some of the wildfires, partially due to favorable weather conditions the past few days.
But they feared that if the winds picked up, it would stoke the fires.
Winds at Mt. Diablo gusted at 51 miles per hour, at about 2 a.m. Saturday.
