'A large number of fire resources are on scene and responding to this rapidly developing wildfire. Firefighters are aggressively suppressing the fire. The communities and resources affected are a top priority,' the federal government's Incident Information System website read. 

The website further stated that the fire is a red flag warning 'due to extremely high temperatures and low relative humidities.'

The National Weather Service had also issued excessive heat warnings across the state till next week. 

The federal agency warned: 'An exceptionally dangerous situation continues to unfold during this potentially historic and deadly heat event. Several days of temperatures well above normal will lead to compounding effects among people and infrastructure with the possibility of numerous heat related fatalities.

'It cannot be stressed enough that while one day at these temperatures may be manageable for some, an event of this scale, magnitude, and longevity will likely rival anything we`ve seen in the last 18 years. 

'Heat is the number one weather related killer in the United States. It is VERY LIKELY that we add to hat statistic if preparations are not taken seriously.'

It went on to urge Californians to drink plenty of fluids, stay in an air-conditioned room, stay out of the sun and to check up on relatives and neighbors.

A separate wildfire - dubbed the French Fire - also ignited near Yosemite on Thursday evening amid the state's brutal - and dangerous - heat wave.

This forced the evacuation of some 11,000 residents, and as of Saturday afternoon, it was only 5 percent contained and had grown to 843 acres.

The inferno not only shut down the main highway into Yosemite National Park, it is one 17 wildfires scorching the West Coast state currently.

The largest of these fires - with only 46 percent contained - is the Basin Fire in Fresno County, which has scorched over 14,000 acres.
