How Monroe County floods

Flash flooding from severe storms and heavy rainfall events dominates the flood profile of Monroe County, Kentucky. Over the last 30-year period recorded in the NOAA Storm Events Database, the county experienced 17 flash flood events and two general flood events, which resulted in one fatality.

Recent occurrences illustrate these risks. On February 28, 2021, a stalled frontal boundary brought waves of heavy rainfall across central Kentucky, resulting in record rainfall and flash flooding. Later, on May 4, 2021, a cold front produced additional showers and thunderstorms over already saturated ground, causing widespread flash flooding and isolated severe wind damage following an earlier EF-1 tornado in Tompkinsville.

According to FEMA National Flood Insurance Program records, historical claims are minimal but split across designations. Zone A recorded one claim with an average payout of $1,872 and an average recorded water depth of 1 inch. Zone X also recorded one claim, with an average payout of $0 and an average recorded water depth of 0 inches. Properties situated within FEMA-designated high-risk Special Flood Hazard Areas, specifically Zone A, should pay the closest attention to these flood risks given the prevalence of localized flash flooding from heavy precipitation.

From the storm reports

Flash Flood · Feb 15, 2025. A strong storm system moved across the Ohio and Tennessee Valleys on February 15th and 16th, 2025, bringing heavy rainfall and flooding, severe weather, and winter weather to central Kentucky. The large scale upper level pattern featured deep troughing ejecting across the central CONUS, with broad southwesterly flow occurring in the low and mid troposphere. Southerly flow helped to draw rich moisture up from the G…

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.

Flash Flood · May 4, 2021. Early on May 3rd, central Kentucky sat in the warm sector ahead of an approaching surface low. Much of the region saw only rain showers, but one isolated cell in southern Kentucky was able to produce a short lived EF-1 tornado in the city of Tompkinsville, KY. ||On May 4th, a cold front, following the first system, produced additional rain showers and thunderstorms on the already saturated ground. The result was w…

Flash Flood · Aug 13, 2020. During this period, a stationary front extended near the Ohio River. This served as a focus for the development of isolated severe thunderstorms, but the main event was heavy rainfall that broke out during the early morning of August 14th. This rain produced areas of flash flooding in multiple counties.

Flood insurance in Monroe County

If a building in Monroe 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.
