How Humphreys County floods

Flash flooding from severe storms dominates the flood risk profile in Humphreys County, accounting for 35 recorded events and 20 deaths compared to 8 standard flood events over the last 30 years. Recent storm systems have driven this hazard, including a potent storm system that brought heavy rainfall and flooding on February 15, 2025, followed by multiple rounds of thunderstorms on March 17, 2025.

National Flood Insurance Program records indicate that high-risk Zone A properties experience the heaviest concentration of losses, with 207 claims averaging $69,606 in payouts and an average recorded water depth of 5 inches. Properties in moderate- to low-risk zones also face documented hazards; Zone X claims averaged $123,935 with an average water depth of 4 inches, unshaded Zone X claims averaged $53,864 with an average water depth of 7 inches, and shaded Zone X claims averaged $27,448 with an average water depth of 3 inches.

Homeowners, real estate agents, and journalists should pay the closest attention to properties located within high-risk Zone A, while recognizing that properties in Zone X designations also carry verified financial and physical flood risks.

Flood · Mar 17, 2025. A potent storm system brought multiple rounds of thunderstorms and severe weather to Middle Tennessee on March 15, 2025. The main risk for severe weather was associated with a line of thunderstorms that tracks east across Middle Tennessee during the afternoon and evening hours. This line produced one EF-1 tornado near Christiana. As this line moved towards the Cumberland Plateau, it strengthened and caused wind da…

Flood insurance in Humphreys County

If a building in Humphreys 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.
