Sky5 video shows the Fairview Fire continues to expand with very limited containment in the mountains south and east of Hemet, California.

The fire was mapped at 9,846 acres in size as of Wednesday afternoon, Cal Fire announced, up from approximately 7,000 acres earlier in the day.

Containment was listed at just 5%.

Two people died trying to escape the flames in their vehicle when the fire first erupted Monday afternoon. A third person in that same vehicle suffered severe burns but survived, officials announced Wednesday.

At least seven structures have been destroyed, including several homes.

The cause of the fire remains under investigation.
