Eaton Canyon Receives First Beneficial Winter Storm Following January Wildfire

Following a 1-2-3 punch by the January 7 wildfire, February 13 debris flow, and March 13 debris flow, Eaton Canyon has finally received its first beneficial winter storm on its long road to recovery. On Tuesday, October 14th, an unusually strong trough of low pressure swinging in from the Yukon Territory brought early-season heavy rain and snow to Southern California. This system, which carried rain rates necessary to produce damaging debris flows at Eaton Canyon, skipped over the area with its heaviest thunderstorms. 

The rain gauge at Eaton Reservoir picked up 2.49″ of rainfall, while Camp Hi-Hill just behind Mount Wilson was treated to a healthy 5.51″. Observers at the Pinecrest Gate waited around for 90 minutes during and just after the heaviest rainfall for a debris flow that ultimately never came. During this storm, the heaviest rain was seen at 8:18 AM with 1.56″ / hr rates being observed. This pales in comparison to the nearly 7.00″ / hr rain rates seen in the February 13th, 2025 debris flow. 

Meanwhile, weeding efforts from County staff and Eaton Canyon Docent Volunteers continued into its 7th week, where 12.3 acres of invasive Black Mustard plants, Castor Bean, and Tobacco Tree have already been cleared. Regrowth following this precipitation will be heavily monitored in all areas, but especially in those areas already serviced.
