IDYLLWILD, CALIF. (CBS/AP) -- Heavy rain aided firefighters who made substantial gains against a week-old wildfire that burned across 42 square miles as thousands of people were allowed to return to their homes in Southern California mountain communities near Palm Springs.
With the arrival of an inch and a half of rain Sunday, firefighters began to beat back the flames and had the blaze 68 percent contained. Rain continued to fall off and on throughout much of the day. Winds were only 5 to 10 mph and humidity was 95 percent.
Full control is expected by Wednesday, reports CBS Palm Springs affiliate KPSP-TV.
"With diminished fire activity, firefighters made great progress with line construction, particularly along the east side toward Palm Springs," U.S. Forest Service spokesman John Miller said.
The fire was still far from extinguished, however.
The thunderstorms helping to douse the flames also brought erratic winds and the threat of flooding, all hazardous conditions for fire crews.
Some 6,000 people fled the idyllic little towns that dot the San Jacinto Mountains between Palm Springs and Hemet after the fire broke out Monday and quickly raged across the heavily wooded area. Twenty-three structures, including seven homes, were destroyed. There were no reports of injuries.
The Riverside County Sheriff's Department lifted evacuation orders for the communities of Idyllwild, Fern Valley and Pine Cove, from which thousands had fled the advancing flames five days before.
Evacuation orders for several smaller nearby communities had been lifted earlier in the day.
The fire was less than two miles from Idyllwild on its western flank. It was a similar distance from Palm Springs below on the desert floor, where an enormous plume of smoke could be seen.
The Palm Springs Aerial Tramway, which carries people nearly 6,000 feet up a rugged canyon to a mountain peak overlooking the tourist resort, was closed Sunday because of unhealthy air quality. Crews were also building fire breaks in the area.
A huge portion of the wooded mountains east of Idyllwild and southwest of Palm Springs were lost to the flames, but the popular forests at the top of the tramway, at about 8,500 feet above sea level, have mostly been saved, KPSP says.
Authorities have said the fire was human-caused, but wouldn't say whether it was accidental or intentional.
More than 1,800 firefighters battled the blaze Sunday, using bulldozers, helicopters and other equipment.
