How Wilkinson County floods

Tropical systems and general heavy rain events dominate the flood profile of Wilkinson County, Georgia, led by 13 recorded tropical storms, 5 floods, 3 hurricanes, and 2 flash flood events over the last 30 years.

Severe weather impacts have been documented in recent years, including Hurricane Helene in September 2024, which brought widespread rainfall totals between 6 and 14 inches across north and central Georgia following a Category 4 landfall in Florida. Additionally, heavy rainfall from an upper-level low pressure system dropped 4 to 5 inches of rain along a line from Rochelle northeast to Irwinton and Washington on November 15, 2018, causing significant flash flooding over saturated soils.

The zones you’ll see on the map

Every colour on the map above is a place on this drawing: where the ground sits relative to the flood FEMA plans for.

Flood insurance in Wilkinson County

If a building in Wilkinson 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.
