Overview
- The Thorn Fire began near Buckthorn and Clover trails and rapidly spread from a structure into vegetation, which started Wednesday and led to immediate evacuation orders.

- Mandatory evacuations and warnings cover areas north and south of Interstate 8, the Golden Acorn Casino in Campo is the designated evacuation point, and I‑8 was closed at Ribbonwood and Crestwood.
- More than 600 firefighters, over 90 pieces of equipment and night‑flying helicopters have been used to strengthen containment lines and make water drops on active flames.
- The fire has produced unhealthy smoke for nearby communities, caused localized SDG&E outages for roughly 130 customers, and remains under investigation while crews focus on extinguishing hotspots and increasing containment.
