What to do
Take the necessary actions to protect flood-prone property. The National Weather Service says coastal residents and managers of infrastructure in the warned area should prepare for rising water and act to protect life and property.
High tides each day occur in the late morning, and that is when roads may close and shoreline erosion may occur. Plan trips around those hours if you can.
If you must travel, do not drive around barricades or through water of unknown depth. Just 6 inches of moving water can knock you down, and 1 foot of moving water can sweep a vehicle away.
If water rises near you, move to higher ground.
Context
FEMA flood-insurance records show 2,447 claims in San Diego County and 3,843 in Orange County, dating from 1978 through 2026 (as of September 9, 2026). These counts cover only insured properties, so they understate total flood losses.
Both counties have had federal flood-related disaster declarations, including 4305 in March 2017 for severe winter storms, flooding, and mudslides. San Diego County also had declaration 4758 in February 2024 for severe storm and flooding.
