At his Wednesday morning briefing, Cal Fire Operation Chief Sean Norman was optimistic about the progress made by 2,522 firefighters over the last 24 hours.

Along the north edge of the blaze, where rugged terrain and heavy fuels have made the firefight difficult, the fire’s advance was halted overnight.

“Yesterday, we saw no forward progress in the fire at all,” Norman said of the northern edge. “The lines held, everything is behaving as we expected.”

Norman said a determined effort by ground crews was added by dozens of air drops all day long on Tuesday by a squadron of helicopters.

“Overall, we are fairly confident,” he said. “We are getting a (weather) pattern change. Each day we will get successively more moisture in the air.”

Cal Fire’s confidence has risen to the point where for the first time they have issued a total containment date. As of Wednesday, total containment was projected to be achieved on Oct. 20.

Meanwhile, two weather fronts that could have possibly brought showers to the burn zone over the upcoming weekend have veered away from the San Francisco Bay Area. Norman said the Cal Fire meteorologist now believes there is a 25 percent chance of a 1/4 of an inch falling across the burn zone over the weekend.

“We are not looking at that as a resolution of this fire,” he said. “We are going to continue with our efforts, boots on the ground and our aircraft to keep this fire in check.”

Cal Fire damage assessment continued to survey areas devastated by the fire. As of Wednesday morning, 625 homes have been destroyed in Napa and Sonoma counties with another 156 receiving some kind of damage.

The vast majority of the 352 commercial buildings destroyed were in Napa County where nearly two dozens wineries have reported some kind of damage from the flames.
