Update (4:15 a.m.) - As fire crews prepare to head into the third week of fighting the Thomas Fire, weather conditions continue to be more favorable.
Incident Meteorologist Rich Thompson says crews will have a window of opportunity for the first part of this week to establish more containment line.
Thankfully, a rather quiet day on the #ThomasFire. The #SantaAnaWinds did not result in any significant problems. Crews will be getting a few days of relatively benign weather to continue to corral the fire before another wind event on Wednesday/Thursday. #cawx— Rich Thompson (@RichIMET) December 18, 2017
Wednesday's wind event is anticipated to produce north-northeast winds 20-30 mph with gusts 40-55 mph and isolated gusts to 60 mph.
Fire officials say crews will continue constructing direct hand line where possible while air support will assist with water and retardant drops.

Petersen calls terrain in the Santa Barbara front and back country "unforgiving," making it difficult or even impossible for hand crews to access.
More air support will assist ground crews today with water and retardant drops as long as weather conditions allow aircraft to fly safely.
Airplanes that scoop water into tanks on the belly of the aircraft, called "Superscoopers," will be dropping water on the fire throughout the day.
The Superscoopers are getting water from Lake Cachuma, where a base camp is set up for firefighters.
Helicopters and fixed wing aircraft have been targeting their drops on the Gilbratar Road area.

While the weather is proving to be much more favorable at this time, Chief Petersen is reminding everyone not to become complacent.
"I told all my crews don't let your guard down just because the weather is better." Petersen said. "And I say the same to residents, this is not the time to go back into your homes."
Fire officials say crews will be working to re-establish contingency and containment lines in the Camino Cielo area after strong winds caused the fire to burn through those barriers.
