MANTON  (AP) — A huge wildfire in California is just the latest destructive blaze to stretch resources across the West during a fire season that has been one of the worst in years.

The fires have left some states with thin budgets to scramble to get people, planes, bulldozers and other tools on fire lines to beat back the flames.

And that's with about a third of the annual wildfire season remaining.

According to the National Interagency Fire Center in Boise, Idaho, the nation as of Wednesday had seen 42,927 wildfires this year, which burned just over 7 million acres.

While the number of fires is down from the 10-year average of 54,209 as of Aug. 22, the acreage was well above the average of 5.4 million acres, said Don Smurthwaite, a NIFC spokesman.

In California, state fire spokesman Daniel Berlant said Wednesday that while crews were getting a handle on many of the fires in the northern part of the state, more lightning strikes in Southern California could trigger a new round of blazes.

"There's no reprieve just yet," Berlant said.

Firefighters in northern California on Wednesday made progress in containing a huge wildfire that has burned dozens of homes and scorched about 38 square miles. It was 50 percent contained Wednesday morning.

The threat to homes dropped from 3,500 earlier this week to roughly 200 residences, officials said.

Fire crews assessing the rural area determined Tuesday that 50 buildings had been destroyed since it was sparked by lightning Saturday. It was unclear when the structures burned and how many were homes.

More than 2,100 firefighters were battling the fire near several remote towns about 170 miles north of Sacramento.

Angie Nelson, 38, of Shingletown and her family were swimming at Whiskeytown Lake on Saturday when they got a phone call saying the fire was advancing on their house.

They drove home and her husband and teenage son climbed on the roof and cleaned the gutters of pine needles and leaves, watered the yard and started putting clothes, family pictures and other mementoes together.

Since then, the couple and their four children have been sleeping on the floor of Nelson's mother's house.

"It's stressful. I can't wait to go home. It's awkward staying at somebody's house, even if it is your mother," she said. "They're really going to appreciate sleeping in their own beds."

Nelson said she still had family pictures loaded in special evacuation buckets from the last time they had to leave their house four years ago. She said her 10-year-old son took a teddy bear, her daughter chose a clothes hanger full of belts. Her teenage son took his collection of super balls.

"I looked back in the car and saw that and said 'What are you doing?' and he said 'Mom, I've been collecting these for months.'"

Elsewhere in California, a large wildfire in Plumas National Forest continued to expand, helped by gusty winds.

The blaze, about 120 miles north of Sacramento, has consumed nearly 98 square miles since it started at the end of July and threatens about 900 homes. It was 37 percent contained Wednesday.

In Washington state, fire crews still hoped to fully contain a week-old wildfire that has destroyed 51 homes and 26 outbuildings and damaged at least six other homes, authorities said.

The fire, about 75 miles east of Seattle, has caused an estimated $8.3 million in property damage.

In south-central Idaho, authorities have spent more than $23 million fighting a fire near the towns of Pine and Featherville and another in a forest near the resort town of Stanley.

Those wildfires have each consumed about 150 square miles, and will not be extinguished for some time, Smurthwaite said.

"We expect to be managing them for weeks to come," he said.
