Officials in San Bernardino County, California, issued an evacuation after a brush fire spread to over 7,000 acres.

Some Southern California residents were forced from their homes Saturday after an explosive wildfire grew by more than 3,000 acres in mere hours – and is burning so intensely that it is creating its own weather.

The battle against a wildfire also got a boost in South Dakota thanks to cooler weather and lighter winds. Residents of the state's second-largest city have been on edge, ready to flee if flames from a nearby blaze moved dangerously close.
