How Meigs County floods

Flash flooding and river flooding equally dominate the historical flood profile of Meigs County, supplemented by occasional tropical storm impacts. Over a thirty-year period, NOAA records document 12 flood events, 12 flash flood events, and 2 tropical storm events. Severe weather systems frequently drive these occurrences, such as a potent storm system that produced heavy rain in January 2024, and a warm front that generated training showers, thunderstorms, and locally heavy rainfall in July 2023.

Federal Emergency Management Agency National Flood Insurance Program records show limited historical claims, reflecting the localized nature of many events. Zone X accounts for 2 claims with an average payout of $15,213 and an average recorded water depth of 0 inches. Zone A accounts for 1 claim with an average payout of $2,516 and an average recorded water depth of 1 inch.

Homeowners, real estate agents, and journalists should pay the most attention to properties situated within designated Special Flood Hazard Areas like Zone A, as well as homes in Zone X that remain vulnerable to heavy rainfall and localized flash flooding from intense summer storms.

From the storm reports

Flood · Jan 9, 2024. A potent storm system with abundant Gulf moisture produced heavy rain, mainly along the spine of the Appalachians thanks to upslope flow in western North Carolina. The heaviest rain impacted streams uphill from Gatlinburg, producing flooding in Gatlinburg, Pigeon Forge, and points downstream.

Flash Flood · Jul 20, 2023. A warm front lifting northward through the area produced training showers and thunderstorms, which produced strong to severe damaging winds and locally heavy rainfall in East Tennessee.

Flash Flood · Jul 11, 2021. A warm and humid air mass remained in place. Diurnal convection produced isolated flash flooding.

Flash Flood · Jun 27, 2018. Repeat convection along a slow moving frontal boundary over a lengthy period generated wind damage and flash flooding across Southeast Tennessee from the evening hours into the following morning.

Flood insurance in Meigs County

If a building in Meigs 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.
