How Bourbon County floods

Bourbon County experiences flood risks primarily characterized by general floods, alongside significant flash flooding driven by severe thunderstorms and heavy rainfall. Historical NOAA data from the last 30 years records 63 flood events resulting in two deaths, as well as 25 flash flood events. Recent flash flood events include those driven by strong systems and heavy rainfall on January 3, 2023, and widespread flooding produced by slow-moving outflow boundaries and severe thunderstorms on May 19, 2020.

National Flood Insurance Program records indicate that claims occur across multiple zones, with the highest concentration in high-risk areas. Zone A accounts for 283 claims with an average payout of $18,862 and an average recorded water depth of 16 inches. Additionally, Zone X_UNSHADED properties have filed 34 claims averaging $19,610 with an average water depth of 16 inches, while Zone X properties recorded 26 claims averaging $19,776 with an average water depth of 6 inches. Zone X_SHADED recorded 12 claims averaging $18,310 with an average water depth of 8 inches, and properties with an unknown zone recorded 40 claims averaging $4,163 with an average water depth of 3 inches. Homeowners and real estate agents managing properties in Zone A and unshaded or shaded Zone X areas should pay the closest attention to these flood risks.

From the storm reports

Flash Flood · Jan 3, 2023. During the overnight hours and into the morning on January 3rd, a strong system moved across central Kentucky, bringing isolated damaging wind gusts and widespread heavy rainfall. The system was associated with a negatively-tilted upper-level trough which moved from the Four Corners region on January 2nd to the upper Midwest by January 4th. A surface cyclone transited in a similar fashion to the upper trough, with…

Flash Flood · May 19, 2020. May 18, the Lower Ohio Valley was primed with a moist atmosphere that was in place from southerly surface flow from the Gulf of Mexico, and as a cold front moved through the region, severe thunderstorms caused tree damage and isolated flooding. On the 19th, the flooding became more widespread as heavy rain was produced from outflow boundaries remaining in the region from the previous day's storms.

Flood · Feb 20, 2019. On February 19, 2019, a broad upper trough dipped south to the Gulf of Mexico and carried abundant amounts of moisture towards the Ohio Valley. Once the moisture was transport was underway, isentropic lift caused 1.5 to 3 of rainfall along the Mississippi and Ohio River Valleys. The higher amounts went as far north as south central Indiana.||On the 20th, an upper trough axis and cold front pushed through southern…

Flash Flood · Jul 3, 2019. Central Kentucky was sitting under an upper ridge in an area of high pressure. The air mass over Kentucky was moisture rich but contained little shear. This resulted in an environment conducive to disorganized severe weather, and that's what happened with the diurnal heating of the day. Outflow boundaries provided forcing to initiate further convection which resulted in tree damage and localized flooding issues th…

Flood insurance in Bourbon County

If a building in Bourbon 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.
