Residents stranded by snowfall in southern California could be stuck for another week. 

San Bernardino County Sheriff Shannon Dicus's estimate was an improvement in the outlook, which was previously forecast for up to two weeks. 

"We’ve said we could push it out as far as two weeks but because of the state’s efforts and the equipment that’s coming in behind us we’re hoping to drop that down to a week," he said on Friday. 

While progress had been made in the last few days, firefighters have had to access emergency scenes using snowcats.

"The enormity of this event is hard to comprehend," California state Assemblyman Tom Lackey said, according to The Associated Press. "You know, we’re thinking, ‘We’re in Southern California,’ but yet we have had an inundation that has really, really generated a severe amount of anxiety, frustration and difficulty, especially to the victims and those who are actually trapped in their own home."

Officials said crews have been dealing with such tremendous depths of snow that removal required front-end loaders and dump trucks rather than regular plows.

California Department of Transportation official Jim Rogers said workers have removed more than 2.6 million cubic yards of snow from state highways during 24-hour shifts.

All highways leading up to the mountains have opened intermittently since last weekend to residents and convoys of trucks with supplies

However, downed power lines have complicated efforts to reopen smaller roads. More snowcats were being brought in, along with a California National Guard crew.
