Flash flooding from severe thunderstorms and tropical weather systems dominates the flood character of Tattnall County. Over the last thirty years, NOAA records show 21 flash flood events, alongside impacts from tropical storms, depressions, hurricanes, and general floods. Recent activity includes heavy rainfall from stationary boundaries producing 5 to 8 inches of rain in May 2025, as well as significant tropical systems such as Tropical Storm Helene in September 2024 and Debby in August 2024.
National Flood Insurance Program records indicate that properties located in high-risk Zone A face the most substantial vulnerability, accounting for 19 claims with an average payout of $25,860 and an average recorded water depth of 24 inches. By comparison, Zone X properties recorded 5 claims with an average payout of $15,216 and an average water depth of 1 inch, while 2 claims in unknown zones averaged $21,502 with no recorded water depth.
Property owners located in Zone A should pay the closest attention to flood risks, as they experience significantly higher average water depths and insurance claim payouts compared to properties in other zones.

The heavy rain developed near a stationary boundary associated with a surface low situated across the lower Mississippi Valley. Some of the heaviest rain fell across Candler and Tattnall counties where automated rain gages and CoCoRaHS observers reported a range of 5-…

Every colour on the map above is a place on this drawing: where the ground sits relative to the flood FEMA plans for.
If a building in Tattnall County is in a high-risk zone (A or V) and its mortgage comes from a federally regulated or insured lender, or is federally backed, flood insurance is required.
Outside those zones it is optional, and often worth having: from 2014 to 2024 nearly one-third of NFIP claims came from outside the high-risk Special Flood Hazard Area. Since Risk Rating 2.0, NFIP premiums are set for each building, so the only reliable price is a quote: FloodSmart.gov or a local agent.
