California currently has several fires blazing, with hot temperatures triggering tinderbox vegetation — making it easy for fires to grow.
Hot winds have also contributed to the fire growth, as they have fanned flames and carried sparks.
The extent of the fires has led to president Donald Trump declaring a state of emergency in California.
On Sunday the US president tweeted: «California wildfires are being magnified & made so much worse by the bad environmental laws which aren’t allowing massive amount of readily available water to be properly utilized.
“It is being diverted into the Pacific Ocean. Must also tree clear to stop fire spreading!»
Where is Holy fire?
Holy fire is the newest of the wildfires tearing their way across California, sparking on Monday just before 1.20pm local time.
Smoke billowed into the air as thick brush went up in flames — dried out by temperatures in excess of 30C in recent days.
The fire began close to Holy Jim and Trabuco Canyon roads, on the west side of the Santa Ana Mountains.
Firefighters struggled to contain the flames, as dry undergrowth caught fire rapidly.
As of Tuesday morning, the fire was at two percent containment, affecting Riverside and Orange counties.
The Holy Fire, which had exploded from 75 to 700 acres within an hour Monday afternoon, was threatening recreation structures in the area of Trabuco Creek and Holy Jim Canyon roads, according to the United State Forest Service.
Holy fire had consumed more than 1,200 acres by 5.40pm on Monday, at 8.19pm the fire had grown to 4,000 acres according to the Cleveland National Forest’s official Twitter account.
This means that the blaze had grown more than three times in size in less than three hours.
Cleveland National Forest reported that Trabuco and Holy Jim Canyons has mandatory evacuation orders in place, as well as El Cariso and Blue Jay campgrounds.
Campgrounds within the Trabuco Ranger District have been closed, alongside road closures for Trabuco Creek, North Main Divide, Maple Springs, Bedford and Indian Truck Trail.
John Wayne Airport has had some flights rerouted due to the blaze.
Orange County Fire Authority (OFCA) have enlisted 300 firefighters from multiple crews to fight the fires, with more firefighters expected to arrive.
OCFA Captain Tony Bommarito has said that the area hadn’t burned since around 1980, causing heavy brush — increasing the challenge for firefighters.
The UK Foreign and Commonwealth Office (FCO) has issued travel advice for those travelling to California:
“Wildfires can spread swiftly, so if you’re in the area you should remain vigilant, monitor local media reports, and follow the instructions issued by local authorities, including obeying any evacuation orders.”
