A wildfire ravaging the hills near Los Angeles had swelled in size by over 1,000 percent by Wednesday, torching dozens of homes and prompting a state of emergency.
The Bridge Fire is one of three out-of-control blazes that have erupted around the United States' second-biggest city, fueled by a punishing heat wave and fanned by gusting winds.
Authorities issued widespread evacuation orders as the fire tore through the towns of Wrightwood and Mt Baldy, destroying at least 33 homes, several cabins, and racing through a ski resort.
"We live in the canyon so that fire was coming right in there, and you couldn't take anything out of there," local resident Jenny Alaniz emotionally told broadcaster KTLA.
"I got the dogs out. Our house is gonna burn," she sobbed.
An AFP journalist in Wrightwood witnessed the aftermath of the fire, where the charred shells of buildings and vehicles stood shrouded in smoke.
The fire broke out early Sunday afternoon in Angeles National Forest north of Los Angeles, and initially remained fairly small.
But by Wednesday afternoon it had roared to 49,000 acres (20,000 hectares), fueled by thick brush that carried the flames into the San Bernardino County community of Wrightwood and the Mountain High ski resort.
- Three trapped -
Los Angeles County Sheriff Robert Luna said three people -- including one of his deputies -- were trapped by the fire in a remote area near Mt. Baldy.
He said thick smoke and blocked roads were hampering the rescue effort.
"Our air rescue crew is working to hoist them out once the smoke clears, and LA County Fire is also trying to get a four-by-four vehicle to get them out," Luna told reporters.
He said all three were understood to be in good health.
Southeast of Los Angeles, the Airport Fire continued to grow Wednesday, racing through vegetation and damaging several homes.
Cal Fire, the statewide fire agency, said seven people had been hurt in the blaze, which has now charred more than 22,000 acres (8,900 hectares).
The blaze erupted on Monday and began racing up canyons and hillsides, including Santiago Peak, which is home to radio and television broadcast towers, though the fire appeared to have left them undamaged.
The flames were also hurtling downslope toward Lake Elsinore, with video from the area showing some structures and vehicles consumed by fire.
Dramatic photographs taken by an AFP journalist show towering walls of flame.
Northeast of Los Angeles, the Line Fire has now burned nearly 35,000 acres.
A number of mountain communities were ordered to evacuate, in an area popular with tourists, and several major access roads were blocked.
- 'Herculean effort' -
Police in San Bernardino County have arrested a man in connection with the fire.
Justin Wayne Halstenberg, 34, from Norco was detained late Tuesday on suspicion of starting the blaze.
California Governor Gavin Newsom, who has declared a state of emergency in response to the fires, visited the command post at the Line Fire on Wednesday.
"California is deploying every available resource to combat these devastating fires, and we'll continue to work in lockstep with federal and local partners in this herculean effort," he said.
More than 5,700 emergency personnel are responding to the three fires, his office said, along with dozens of aircraft and over 500 fire engines.
"We are deeply grateful to all the heroic firefighters and first responders... working 24/7 to keep Californians safe," Newsom said.
A persistent heat wave that has gripped much of southern California for a week was easing Wednesday, and officials were hopeful that lower temperatures might make the battle against the fires easier.
Wildfires are a natural part of the wilderness cycle and are not unusual in California and other parts of the US West at this time of year.
But after two relatively mild fire years, 2024 is shaping up to be significant.
A couple of very wet winters generated abundant growth of vegetation, which has now dried out after a long, hot summer, leaving behind lots of fuel.
Hurricane Francine batters Louisiana
Hurricane Francine slammed into Louisiana Wednesday with potential for life-threatening flooding and storm surge as residents of the southern US state were advised to hunker down indoors.
The storm weakened as it moved over land, forecasters said, but it was still causing flooding, power outages and heavy rain and wind. A flash flood emergency was issued for the city of New Orleans.
Francine made landfall as a Category 2 hurricane on a five-level scale in Terrebonne Parish on the southern edge of the state at 5:00 pm local time (2200 GMT), according to the National Hurricane Center (NHC).
Two hours later the storm was downgraded to Category 1 with sustained winds of 85 miles (140 kilometers) per hour and could bring up to 10 feet (three meters) of storm surge and a foot of rain in some parts of Louisiana, the NHC added.
"Life-threatening storm surge, hurricane-force winds and heavy rains continue to affect southern Louisiana," the NHC said in a bullet at 0000 GMT.
The National Weather Service's New Orleans office issued a flash flood emergency for the city and nearby districts known as parishes, while New Orleans Mayor, LaToya Cantrell, urged residents to shelter in place.
"You need to be inside right now. Time to hunker down," Cantrell said in a video posted to social media.
Local TV stations and footage on social media showed coastal towns battered by the storm, with some streets flooded. More than 300,000 customers across Louisiana were without power, according to monitoring website poweroutage.us.
In the town of Houma, residents filled sandbags, stocked up on supplies and filled their cars with gas ahead of the storm's arrival.
"We're working hard to stay here as long as we can... to take care of our people," a gas station manager who gave her name as Alicia B. told AFP.
The NHC said the storm is expected to quickly weaken as it moves inland over Louisiana and neighboring Mississippi.
Louisiana Governor Jeff Landry has declared a state of emergency, and on Tuesday requested a federal emergency declaration from President Joe Biden, which he quickly approved.
The Louisiana National Guard said on X that its soldiers were fuelling up vehicles in preparation for the storm. On Tuesday, it said it was mobilizing helicopters, boats and supplies for evacuations and search and rescue.
Schools and universities around the capital Baton Rouge were preemptively closed until Friday, according to a government website.
Curfews starting as early as 6:00 pm local time (2300 GMT) were issued for communities across the Louisiana capital region, local media reported.
Low-lying Louisiana was the site of one of the most devastating hurricanes in US history, Hurricane Katrina, which killed more than 1,300 people as it slammed into populous New Orleans in late August 2005, overwhelming the city's levee system and causing extensive flooding.
At the mouth of the Mississippi River, Louisiana is a major US trade hub with a significant part of its economy linked to the oil and natural gas industry.
The 2024 Atlantic hurricane season, which began on June 1 and will end November 30, was expected to be busy but has seen just three hurricanes so far, reportedly puzzling scientists.
Hurricane Beryl became the earliest highest-level Category 5 storm on record after it formed in late June and plowed through the Caribbean, eventually hitting Texas and Louisiana, with dozens of deaths reported in its wake.
Scientists say climate change likely plays a role in the rapid intensification of storms because there is more energy in a warmer ocean for them to feed on.
