A fast-moving wildfire on the Cuesta Grade north of San Luis Obispo prompted an evacuation order Wednesday as firefighters worked to slow flames burning along Highway 101.
The fire, identified in local reports as the Cuesta Fire, began after a vehicle caught fire on northbound Highway 101 near Stagecoach Road. The driver was reportedly able to get out of the vehicle before the flames spread into nearby vegetation.
By Wednesday afternoon, reports citing CAL FIRE said the fire had grown to approximately 33 acres, while another local report later put the burned area at about 40 acres. The fire remained 0% contained in the latest available reporting.
Evacuation Order and Fire Response
An evacuation order was issued for Zone LPF-004 as authorities monitored the fire’s movement and its proximity to surrounding areas. Fire crews were working to establish control lines while aerial resources conducted suppression missions when conditions permitted.
Approximately 75 personnel were assigned to the incident in the latest report. The response included nine engines, a water tender, one helicopter, two bulldozers and one hand crew. Numerous firefighting air tankers from across California were also reported to be assisting.
Highway 101 Traffic Impact
The fire has also affected traffic along the Cuesta Grade. The blaze began near northbound Highway 101, and motorists in the area were experiencing significant delays as emergency crews operated near the roadway. KSBY reported that northbound traffic was backed up while firefighters worked at the scene.
Drivers traveling through the area should monitor official Caltrans and CHP updates before entering the Cuesta Grade and follow any evacuation or traffic-control instructions.
