Wildfire season is upon us as a massive fire is burning along the Arizona-California border.
The "Topock Fire" started Wednesday morning and it's already prompted some evacuations.
By Thursday afternoon, the fire had grown to over 2,200 acres and was 40% contained.
It began as a brush fire in western Arizona, but quickly jumped the Colorado River and spread into California, burning in the Havasu National Wildlife Refuge on both sides of the border.
Two RV parks in California have been evacuated and crews from Fort Mohave, Golden Shores, Bullhead City and San Bernardino are fighting the fire, which is being called suspicious. The Bureau of Land Management, Arizona Game and Fish Department have firefighting units at the scene as well.
Officials say the Topock Marina is also threatened by the blaze that has damaged one structure so far.
Firefighters have brought in 1 airplane, 2 helicopters, 2 Department of Corrections firefighter crews, numerous wildland and structural fire crews to fight the fire.
MUST WATCH: Firefighters are battling the #PirateFire near Lake Havasu City, along the Arizona-California border. Evacuations are in place and the fire has burned over 1,200 acres. (Video: San Bernardino County Fire)Posted by FOX 10 Phoenix on Wednesday, April 6, 2016
