Shaded areas are FEMA’s mapped flood hazard zones in and around Glynn County, Georgia. Zoomed out they are simplified; at street level the map switches to FEMA’s exact layer. Tap anywhere to check that spot, or search an address above.
Tropical storms and coastal flood events drive the primary flood hazards in Glynn County, supported by a historical record dominated by 27 tropical storms, 15 general floods, 15 coastal floods, and 4 flash floods over the last 30 years. Recent occurrences illustrate these risks, including an extended duration local nor'easter wind event in October 2025 that brought gusty winds of 40-51 mph and moderate tidal flooding to the coast and inland waterways, alongside heavy rainfall from onshore flow associated with a surface front in August 2025 that caused localized flooding. Additionally, Hurricane Helene tracked north-northeast through the region in September 2024, generating peak wind gusts of 55 to 75 mph across the eastern half of the area.
NFIP claims data demonstrates that risk extends across multiple zones, led by Zone A with 1,546 claims averaging a $32,442 payout and an average recorded water depth of 5 inches. Zone X accounts for 371 claims with an average payout of $29,417 and an average recorded water depth of 5 inches, while Zone V records 39 claims with an average payout of $41,082 and an average recorded water depth of 1 inch. Homeowners and real estate agents in high-risk coastal and inland flood zones, particularly Zone A and Zone V properties, should pay the closest attention to these persistent tropical and tidal vulnerabilities.
Summary written from NOAA storm reports and NFIP claims for this county. Not a prediction.
Less than 1% of Glynn County’s flood insurance claims were on properties rated outside FEMA’s high-risk zones.

In flood insurance claims here that reported a flood depth, the average was 5 inches.

Coastal Flood · Oct 9, 2025. An extended duration local nor'easter wind event developed October 9th and persisted through the 12th between high pressure wedging down the SE US coast and a sharpening coastal trough axis over the local coastal waters. Gusty winds of 40-51 mph impacted coastal areas, with the strongest winds from 10/9 in the afternoon through 10/10 in the evening along the Duval county coast of 51 mph. Tidal flooding reached mod…
Flood · Aug 9, 2025. A surface front was across southeast Georgia. Onshore flow across coastal southeast Georgia near and just north of the front produced banding waves of heavy rainfall during the morning which caused localized flooding issues.

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 Glynn 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.
