SAN FRANCISCO (KGO) -- Just as the massive lightning complexes of August were just about contained in the Bay Area, a new wildfire is threatening communities in Napa and Sonoma counties -- areas all too familiar with the threat.

The Glass Fire started at 4 a.m. Sunday, Sep. 27 and began spreading at a dangerously high speed, fanned by high winds. Overnight Sunday into Monday morning, the Glass Fire spawned two new fires: the Boysen and Shady fires. According to CAL FIRE, those smaller fires have since merged with the Glass Fire, forming one incident.

An investigation team is on scene looking at the cause of the Glass Fire, as well as the two smaller fires that merged into it. "It's too early to tell exactly how this fire started but under these incredibly dry conditions with these gusty winds, it obviously didn't take much - a simple spark, an open flame - to allow this fire to grow," said Daniel Berlant, assistant deputy director at CAL FIRE, in an interview with ABC7 News on Sep. 28.
