A fast-moving wildfire forced the complete shutdown of Interstate 5 through the Grapevine on Thursday afternoon.
The Danny Fire erupted south of Gorman, north of Smokey Bear Road, in Southern California, triggering urgent evacuation warnings as flames threatened the critical highway corridor linking the state’s northern and southern regions. By approximately 4:30 p.m., the blaze had grown to an estimated 5 to 10 acres, according to Watch Duty.
Crews responding to the incident faced dangerous conditions from the outset. A helicopter surveying the fire reported a moderate rate of spread as ground teams mobilized to contain the flames.
The initial report came shortly after 4:15 p.m., when the fire covered roughly 2 acres and was burning through light to medium vegetation with a fast rate of spread, according to radio traffic monitored at the scene. Firefighters quickly warned of a potential threat to structures within 15 to 20 minutes of that first alert.
Both directions of Interstate 5 were closed through the Grapevine as the fire burned near the major travel artery. The shutdown affected the primary route connecting Southern and Northern California, disrupting traffic across a key economic and transportation corridor.
Evacuation warnings were requested for multiple zones: GOR-E004, GOR-HUNGRYVALLEY-A, and GOR-HUNGRYVALLEY-B. The warnings covered areas near the fire’s perimeter as officials assessed the spreading threat.
The cause of the fire was not immediately known. Fire officials had not determined what sparked the blaze as crews continued working to establish containment lines and protect threatened structures.
The Danny Fire added to an already active wildfire season across California, where dry conditions and wind have repeatedly created dangerous fire weather. The Grapevine section of I-5, winding through mountainous terrain, has historically been vulnerable to weather-related closures including those caused by wildfire activity.
