The Morgan Fire on Mount Diablo is now 45 percent contained, Cal Fire officials reported Tuesday morning, with mandatory evacuations still in effect.
Cal Fire reports the blaze has scorched 3,243 acres, a figure about 500 acres smaller than reported on Monday. Officials said "better mapping" led to the downgrade in acreage.
Firefighters have contained the fire in the area where it jumped Morgan Territory Road on Monday night.
Three injuries have been reported. One firefighter injured a foot, while two others were treated for heat exhaustion on Monday.
Mandatory evacuations remain in effect for several neighborhoods on the east side of the mountain, said Robert Marshall, spokesperson for the Contra Costa County Fire Protection District.
"There's not a lot of fire out there, but there's fire in the trees," Marshall said. "We're concerned about the trees falling over...They're big enough to kill people," he told Patch Tuesday morning.
Portions of Marsh Creek Road, Morgan Territory Road and Deer Valley Road remain closed near the fire zone.
Marshall said he has zero reports of homes lost in the fire from any of the three divisions of firefighters battling the blaze. One communication structure was damaged.
He expects the fire to remain under control today. Winds are expected to blow at about 3-8 mph today, which reduces the chance that they will blow the fire onto other areas. The winds were clocked at 16 mph on Monday, gusting to 26 mph, according to the weather.com. Today they are blowing south west, which may or may not be a problem.
"Today the humidity is up," Marshall said. "Our main worry is not that the fire will get bigger, but that the little areas of fire will become a danger," he said, highlighting the fact that the tree canopy and falling branches are more of a problem.
More than 700 fire personnel and 100 engines are battling the flames.
The cause of the fire hasn't been determined.
"Hopefully we can get everyone back into their homes soon," he said.

"Things seem to be moving in the right direction," he said.

Bolded sections indicate an update.
The absence of a strong wind was about the only break fire crews caught as they fought a fast-growing blaze on the eastern slope of Mount Diablo Sunday night and Monday morning.
The fire, which was first reported off Morgan Territory Road at 1:08 p.m., expanded with such ferocity that it triggered an evacuation order for people in the homes about seven miles south of Clayton, California.
Between 6:15 and 7:30 p.m. it doubled in size, ballooning from 400 to 800 acres. (For a chart of the latest fire statistics, click here.)
Smoke billowing hundreds of feet above Mount Diablo was visible from as far away as San Francisco and Marin County.
At 8:41 a.m. Monday the fire was 1,500 acres and 10 percent contained, according to Cal Fire.
The blaze started on the lower slopes of the mountain near the intersection of Morgan Territory and Marsh Creek roads. By nightfall, it had burned all the way up the southeast side of the mountain. Firefighters say parched brush fueled the fire.
About 7:30 p.m. the flames had advanced close to the summit of North Peak. Fire trucks lined the peak, attempting to halt the fire’s ascent, while down below public officials ushered people to safety.
When the fire threatened 75 structures Sunday afternoon, public safety officials ordered residents of Oak Hill Lane and Curry Canyon Road to evacuate to the Clayton Community Library. Contra Costa sheriff’s deputies rolled through the neighborhoods at about 4 p.m., using loudspeakers to inform people there was a mandatory evacuation and that they needed to leave immediately.
By Sunday evening, about 250 firefighters from six departments were working to halt the fire’s progress. Air tankers and helicopters doused the fire from above until darkness grounded the aircraft.
Dennis Rein, a public information officer for the Contra Costa Fire Protection District, said Sunday evening the fire would probably burn all night and into morning.
Rein said fighting a fire on the mountain is tough, but it’s particularly tough on that side of Diablo. There are few fire roads and the terrain is steep.
He said the town of Clayton appeared safe for the time being.
On Sunday evening, people walked the streets of the small town, peering up at the smoky mountain top.
“Any fire on that mountain is scary,” said Clayton Mayor Julie Pierce, who was at the library waiting for evacuees.
At 7 p.m., only a handful of people from the fire area had arrived at the library.
One of them was a woman who identified herself as Virginia. She lives in a trailer park in the Morgan Territory area.
She said there was a lot of smoke in her neighborhood throughout the afternoon. Residents couldn’t see the flames, but they were a “bit concerned” about the fire.
Virginia grabbed “a few things you can’t replace” such as photographs and drove to the Clayton Library.
She didn’t know when she’d be allowed back home and at that time she wasn’t sure where she would sleep Sunday night.
American Red Cross volunteers were at the library, trying to find accommodations.
People with horses boarded in the fire zone were advised to take their animals to the equestrian center at Heather Farm Park in Walnut Creek.
A short distance away at the park and ride lot at the Peacock Creek housing tract, members of the Concord Mount Diablo Trail Ride Association had gathered.
The members had driven out to stables in the fire zone and evacuated two dozen horses.
Elaine Baker, a Concord resident and member of the association, said they didn’t wait for evacuation orders to go get the horses.
“Even if it seemed premature and silly, we wanted to go out there,” said Baker. “It wasn’t silly to us.”
