California Wildfires: Sonoma Sheriff gives press briefing - live updates

Sonoma County Sheriff Rob Giordano gives a press briefing on on the North Bay wildfires. The briefing will take place at 9a.m. PT Thursday at the sheriff's office at 2796 Ventura Ave. in Santa Rosa. "It's going to continue to get worse before it gets better," state fire Chief Ken Pimlott said Wednesday.

With fires advancing from several sides in Sonoma Valley, law enforcement officers on loan from other areas barred residents of evacuated communities from returning to see how their homes and businesses had fared. Roadblocks were set up between Sonoma and devastated areas of Santa Rosa.

This is a developing story and will be updated.
