Cherry Fire Scorches 90 Acres Along Interstate 10 in Calimesa, Reaching 65 Percent Containment

CALIMESA, Calif. — A fast-moving vegetation fire broke out alongside Interstate 10 in Calimesa on Monday morning, forcing temporary lane closures, halting local traffic, and scorching nearly 90 acres of open space. Dubbed the Cherry Fire, the blaze ignited just before 11:00 a.m. near the intersection of westbound Interstate 10 and Cherry Valley Boulevard. Fueled by dry conditions, the flames moved at a moderate rate through heavy brush, prompting an immediate and robust response from Cal Fire and the Riverside County Fire Department to protect nearby commercial structures and the critical transportation corridor.

As of Monday afternoon, fire officials confirmed that the forward rate of spread has been completely stopped and the perimeter is now 65 percent contained. The extensive battle on the ground and in the air required the deployment of over 100 personnel, including 17 fire engines, four hand crews, two bulldozers, and three water tenders. At the height of the firefight, multiple air resources were called in to suppress the flames, with three specialized Cal Fire air tankers dropping fire retardant and two helicopters dropping water to keep the fire from crossing the interstate or jumping into adjacent neighborhoods.

The intense emergency response and heavy smoke conditions created significant logistical challenges for regional transit. Officers with the California Highway Patrol initially shut down two westbound lanes of Interstate 10 for public safety, eventually modifying the restriction to a single lane and the shoulder. Despite leaving three lanes open, the traffic backlog extended for miles as motorists slowed down through the pass. Additionally, local authorities completely shut down Cherry Valley Boulevard between the freeway and Hannon Road to clear the roadway for staging heavy firefighting equipment, causing widespread surface street delays throughout the afternoon.

One firefighter suffered a minor injury during the grueling containment operations and was transported by ground ambulance to an area hospital for further evaluation and medical treatment. No civilian injuries have been reported, and no mandatory evacuation orders were issued for nearby residential communities as crews successfully established firm hose lines around the burn scar. Firefighters are expected to remain committed to the scene for several hours to conduct extensive mop-up operations, douse remaining hot spots, and ensure that no flare-ups occur in the dry afternoon heat. The exact cause of the brush fire remains under active investigation by Cal Fire officials.
