What to do
Take steps now to protect flood-prone property. Move valuables and vehicles away from low-lying spots near the shore, especially before the morning high tides.
If you must travel, do not drive around barricades or through water of unknown depth. The National Weather Service warns that just 6 inches of moving water can knock you down, and 1 foot of moving water can sweep a vehicle away.
Stay alert for rising water. If water is rising near you, move to higher ground. Check local updates from the National Weather Service for changes to the warning.
Context
FEMA flood-insurance records show 2447 claims in San Diego County and 3843 in Orange County between 1978 and 2026. These counts only cover insured properties, so they understate total flood losses.
Both counties have had federal disaster declarations that involved flooding, including a 2017 declaration for severe winter storms, flooding, and mudslides that covered both.
