BANNING, Calif. — A wind-driven fire that started in an RV and jumped to vegetation alongside Interstate 10 in Banning Friday scorched 86 acres and prompted closures on the freeway before it was stopped.

The non-injury blaze was reported just before 2 p.m. on westbound I-10 at the Ramsey Street exit, according to the California Highway Patrol.

Multiple Riverside County Fire Department, Morongo Tribal Fire Department, Palm Springs Fire Department and other engine crews were sent to the location, encountering flames moving at a rapid rate to the east, in the direction of a Caltrans storage yard and tractor-trailer weight scales, where numerous propane tanks are stored, the CHP and county fire officials said.

Cal Fire air tankers and water-dropping helicopters initiated runs on the brusher shortly before 3 p.m., aiding crews in establishing containment lines.

As of 3:45 p.m., the fire’s forward rate of spread had been stopped and it was 50% contained, according to the fire department.

There were no reports of damage to structures.

CHP officers shut down the Ramsey exit ramp and the westbound slow lane for public safety, leading to a SigAlert because of the ensuing traffic jam.

The closures were expected to be lifted by 6 p.m.

The exact source of the fire within the RV was under investigation.
