All evacuation orders have been downgraded to warnings on the six-alarm fire.
Residents in the Woodside and Portola Valley areas should expect to smell smoke from the fire over the next 72-96 hours as crews continue to reach full containment, fire officials said.
During a briefing Tuesday, officials said the fire is burning in a north to northwesterly direction towards north Canada Road and crews are actively working to protect homes at risk of catching fire.
Officials say a firefighter was injured while battling the blaze and has been taken to the hospital. Their condition is unknown at this time.
Multiple agencies are assisting in the fire response, which includes support from the air, the CAL FIRE spokesperson said.
CAL FIRE confirmed the blaze was extremely close to homes.
"We hit it really hard yesterday with aircraft. We have a good line around it. We scraped the ground so the fire cant cross," said CAL FIRE Battalion Chief Bob Simmons.
Kathy Hibbs and her family decided to evacuate after 2:30 p.m. She described seeing smoke and flames as they drove off.
"We heard one report because somebody was up in one of the copters. It was basically 200 feet from where the pavement is. Which is awfully close," said Hibbs.

"We had a checklist that I was going through and we were just yelling at each other, like, what do we need to do, what am I supposed to do," said Leo Gray.
Down the block, Bruce Baker decided to stay back. He's lived in the neighborhood for 40 years and said this has been their closest call.
"I cant imagine people losing their homes. Up in Paradise, Chico and Santa Rosa. It hits home now more than ever," said Baker.
Bruce described hearing what sounded like an explosion around 2:20 p.m. and then they lost power.
"I heard a big boom," said Baker.
As PG&E crews could be seen around the area.
Luz Pena: "Any idea of what may have caused this fire?"
CAL FIRE Battalion Chief Bob Simmons: "I have investigators out here right now. Working hard on determining the cause of the fire."
For many residents, Tuesday's fire was a close call that reminded them of the importance of always being prepared with an evacuation plan.
Firefighters initially responded to two fires shortly after 2:20 p.m. in the area of Edgewood Road and Crestview Drive and the California Highway Patrol reported that smoke was visible from Interstate Highway 280.
