(CNN) -- Residents near a fast-growing wildfire in Southern California were evacuated Wednesday as hundreds of firefighters tried to contain the blaze that had grown to 1,700 acres.
One firefighter suffered minor injuries, the Riverside County Fire Department said.
There were no exact numbers on how many people had been evacuated as of Wednesday evening, but authorities said a 200-unit mobile home park in Cherry Valley had been cleared and some residents in Banning were told to leave their homes. Banning is about 25 miles west of Palm Springs.
The fire department said on its website that 425 fire fighters were involved in efforts to douse the flames.
CNN affiliate KTLA said at least one home was burned as 30-mph winds drove the flames.
The National Weather Service in San Diego said a red flag warning was in effect until Friday evening. Forecasters called for wind speeds between 15 and 25 mph with gusts up to 55 mph.
