Sandy Fire burns near Simi Valley, forces evacuations across Southern California
Wind-driven flames near Simi Valley grew to nearly 1,700 acres, pushing as many as 43,000 people from their homes before containment reached 15%.

Relentless winds and bone-dry hillsides turned the Sandy Fire into a moving evacuation crisis across Southern California, pushing flames toward suburban neighborhoods near Simi Valley and sending tens of thousands of residents scrambling for safety. The fire, reported May 18 off Sandy Avenue in Simi Valley, kept growing through Wednesday as shifting winds and steep canyon terrain accelerated its spread.
By Wednesday morning, the fire had burned nearly 1,700 acres and was 15% contained, a day after it started at 0% containment. CAL FIRE said 750 firefighters were assigned to the blaze, with night-flying water-dropping helicopters supporting suppression efforts. Officials said the fire’s behavior was being shaped by dry conditions, gusty winds, and canyon-driven runs that made the incident difficult to pin down.
The evacuation burden changed quickly as the fire moved through Ventura County and into concern areas in Los Angeles County. More than 17,000 people were under evacuation orders at one point on Tuesday, after earlier orders affected as many as 43,000 residents. An evacuation center opened at Rancho Santa Susana Community Park in Simi Valley, where the American Red Cross Pacific Coast Chapter and the Ventura County Human Services Agency supported displaced evacuees.

California also secured federal firefighting assistance on May 18 to reinforce the response in Ventura County, as crews tried to slow a fire that had become part of a broader Southern California emergency. The National Weather Service warned of critical fire weather conditions across the region as gusty winds, very low humidity and warm, dry weather continued to raise the risk of new starts and erratic fire spread.
Forecasts later pointed toward improving conditions as onshore winds strengthened and humidity rose, offering some relief to firefighters who had been battling consecutive days of dangerous weather and fast-moving flames. Even so, the Sandy Fire remained a reminder that repeated fire exposure is no longer a one-day disruption for communities on the edge of the wildland, but a recurring strain on evacuation systems, local shelters and regional firefighting resources.

The cause of the fire remained under investigation.
