So far, the wildfire is 30 percent contained, has destroyed at least 39 homes and scorched 69,600 acres. Crews were able to make progress Tuesday due to cooler temperatures and higher humidity, but those favorable weather conditions started to change Wednesday afternoon.
"Today, we are already starting to see temperatures on the rise. The humidity is lower and that has the potential this afternoon and this evening for fire activity to pick back up," Cal Fire spokesman Daniel Berlant said.
Gov. Jerry Brown will visit fire and emergency officials at the Rocky Fire Tuesday morning.

The number of homes destroyed has now climbed to 39, up 15 from Monday. It is not because of any new fire activity, but because the inferno has finally died down, allowing officials to get in and see what it left in its wake.
On Wednesday, firefighters focused on dousing hot spots as they appeared along Highway 20, with fortunately, no major head of flames to contend with.
"Conditions are holding up. The ground forces are going in and they're doing great work on mop-up, but it's that time of day, recently in the past week that we get a lot of flare-ups," Rocky Fire spokesman Mike Yeun said.
The hope now is to have the Rocky Fire completely contained by next Monday -- that is if the weather cooperates.
That's good news for the thousands still evacuated from their homes. ABC7 News spoke to a couple who left their home in Spring Valley and have been at a Red Cross shelter in Middletown for four days.
"We're getting tired, we're getting real tired. This is like our third time out, third fire from living in that area. So we were prepared, we knew what to do, but you still worry," evacuee Ginna Powers said.
Joan Jacobs came to the shelter as a resident looking for help, but soon found herself, working as a Red Cross volunteer.
"As corny as it might sound, I felt like a found a new family here. Anything anyone needs, they're there... and if I can contribute, I want to do that," Jacobs said.
There are 13,000 people who had to evacuate.
