Fresno's overall natural disaster risk is rated 6.7/10 (High) by FEMA's National Risk Index.

Reviewing insurance coverage for drought and secondary hazards, registering for emergency alerts, and maintaining a household emergency kit are practical steps that can significantly reduce impact during a major event.
