The Madre Fire has grown to 35,530 acres in less than 24 hours, making it this year's largest wildfire in California.

While the Fourth of July is typically an explosive holiday with dazzling fireworks at night, CAL FIRE/San Diego County Fire Capt. Mike Cornette warned revelers to be cautious this year.

San Diego first responders are working extended hours this holiday weekend to ensure safety at local beaches and beyond.
