Ventura County firefighters are trying to put out a brush fire in Simi Valley.
It started just after 4p.m. in the hills near Los Angeles Avenue and Stearns Street.
At least 10 fire engines, two helicopters and two fixed-wing aircraft are assigned to the fire.
The 30-acre fire caused Metrolink to shut down service.
No word on when service will resume.
Winds appear to be blowing the flames away from homes.
Every new fire serves as a reminder that fire season has only just begun.
