El Niño Flood Preparedness and AlertMarin Test

California’s statewide emergency declaration reinforces preparation for potentially severe El Niño storms, including flooding, king-tide inundation, mudslides, outages, and transportation disruption across Bay Area shoreline and low-lying communities. Projected Kelvin waves could add 6–12 inches to sea levels; Marin County will test AlertMarin on September 26. Recent coverage reiterates go-bags, alerts, sandbags, and evacuation planning without reporting a new local operational impact.
