How Green County floods

Flash flooding dominates the flood character of Green County, Kentucky, accounting for the majority of local flood events over the last 30 years compared to standard riverine floods. NOAA storm records illustrate this hazard, including a heavy rainfall event in February 2021 driven by a stalled frontal boundary, and multiple rounds of widespread precipitation dropping 2 to 4 inches of rain from New Year's Eve into New Year's Day 2022. Additional flash flooding occurred overnight into the morning of April 3, 2025, as severe storms and a stalling cold front tracked across the region.

National Flood Insurance Program records indicate historical claims concentrated in Zone A, totaling 3 claims with an average payout of $68,361 and an average recorded water depth of 0 inches. Homeowners, real estate agents, and journalists should pay the most attention to properties situated in Zone A, where historical claims have occurred.

From the storm reports

Flash Flood · Apr 3, 2025. On the night of April 2nd, 2025, a cold front approached the lower Ohio Valley. Along and ahead of the cold front, numerous supercells developed over southern Illinois and western Kentucky. These storms tracked eastward and occasionally grew upscale into a QLCS with bowing segments. Storms lasted all night and into the morning hours, as the cold front began to stall over the lower Ohio Valley. These storms left be…

Flash Flood · Jan 1, 2022. During New Year's Eve into New Year's Day, active weather was observed across Kentucky as several waves of low pressure moved along a frontal boundary that was stalled across the region. This resulted in multiple rounds of widespread precipitation, and rainfall amounts of 2 to 4 inches with locally higher amounts observed across the area. As the boundary lifted north as a warm front New Year's Day, strong to sever…

Flash Flood · Feb 28, 2021. A stalled frontal boundary brought waves of heavy rainfall to central Kentucky from February 26 through February 28. This caused record rainfall, isolated severe winds, and even a tornado. As a result, Bowling Green set a February daily rainfall record with 5.11 on the 28th. The severe winds brought down some trees and a power pole, but the most property damage came from a brief EF1 tornado.

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 Green County

If a building in Green 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.
