The facts so far

As reported. Each one links to where it comes from.

  • Monterey County declared a local emergency to prepare for a potential El Niño winter.ksbw.com
  • Officials anticipate flooding, rising seas, and debris flows, particularly in areas impacted by this summer's Big Sur fires.ksbw.com

Why it matters

The integrity of Highway 1 is critical for regional connectivity, especially given the existing risks posed by past wildfire activity in Big Sur. Severe flooding and debris flows could lead to significant operational disruptions, requiring major maintenance and potentially causing long-term closures of the route.

Monterey County is proactively preparing by allocating funds and suspending state regulations to expedite the clearing of river channels and creeks. This preparation highlights the county's recognition of the severe potential impacts of a strong El Niño winter, which is a major climate driver across the Americas.

What would change this answer

The county announces a specific timeline for culvert and drainage clearing projects.This would increase the certainty of the mitigation efforts, potentially reducing the severity or duration of the operational disruption on Highway 1.
The El Niño forecast is downgraded from 'very strong' to 'moderate'.The anticipated risk of severe flooding and debris flows would decrease, making the operational disruption on Highway 1 less likely.
