How Covington County floods

Flash flooding from severe weather and summer thunderstorms dominates the flood profile of Covington County, which recorded 51 flash flood events alongside impacts from tropical systems over the last 30 years. Recent impacts include Tropical Storm Francine in September 2024, which brought heavy rain and strong wind damage across central Mississippi as the system moved through the region. Additionally, a slow-moving low pressure system produced heavy rainfall and widespread flooding of roads, homes, and businesses in August 2022.

National Flood Insurance Program records indicate that high-risk Zone A areas experienced the highest frequency of claims with 44 filings averaging $17,596 and an average recorded water depth of 10 inches. Properties in Zone X also recorded significant losses, with 6 claims averaging $38,224 and an average water depth of 2 inches. Zone UNKNOWN accounted for 20 claims averaging $6,178 and an average water depth of 3 inches, while Zone X_UNSHADED recorded 1 claim averaging $4,049 with 0 inches of recorded water depth.

Homeowners and real estate agents should pay the most attention to properties located within Zone A and Zone UNKNOWN, where the vast majority of historical insurance claims and deeper recorded water levels are concentrated.

From the storm reports

Tropical Storm · Sep 12, 2024. Tropical Storm Francine made landfall in southern Louisiana on the evening of September 11th, 2024. The weakening storm produced strong wind damage as it moved across central Mississippi the morning of September 12th, 2024.

Flash Flood · Aug 24, 2022. A low pressure system spinning over northern Louisiana and southern Arkansas brought several rounds of showers and thunderstorms producing heavy rain to Mississippi August 24th through 25th. This resulted in widespread flooding of roads, homes, and businesses around the state.

Flash Flood · Jul 22, 2022. Slow moving thunderstorms on the afternoon of July 22nd resulted in flash flooding in Covington County near Collins.

Flash Flood · Mar 18, 2022. Showers and thunderstorms developed in the warm, moist airmass south of a warm front. Some storms were severe and produced wind damage to portions of southeast Mississippi. Flash flooding occurred as storms began to move over the same region.

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 Covington County

If a building in Covington 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.
