How Neshoba County floods

Flash flooding from severe summer thunderstorms dominates the flood risk profile in Neshoba County, Mississippi, accounting for 44 out of 54 total recorded flood events over the last 30 years, alongside 5 general floods, 3 hurricanes, and 2 tropical storms.

Recent occurrences illustrate this severe weather pattern. During an event in June 2023, an upper-level shortwave trough and unstable air mass triggered clusters of thunderstorms and a rare June tornado outbreak that produced multiple flash floods across the area. Another flood event occurred on June 5, 2024, when remnant outflow boundaries from previous storms sparked renewed thunderstorm development and severe weather throughout eastern Mississippi.

National Flood Insurance Program records indicate that claims have been filed in lower-risk areas, including Zone X with 5 claims averaging a $13,757 payout and an average recorded water depth of 1 inch, and Zone UNKNOWN with 3 claims averaging an $11,557 payout and an average recorded water depth of 1 inch. Homeowners and real estate agents managing properties in these mapped zones, particularly those without designated base flood elevations, should pay close attention to potential flash flooding driven by heavy seasonal rainfall.

From the storm reports

Flood · Jun 5, 2024. During the afternoon of June 5th, a remnant outflow boundary from the previous day's storms became the focus point for renewed thunderstorm development. Numerous strong to severe storms formed along a line producing damaging wind in eastern Mississippi.

Flash Flood · Jun 19, 2023. An upper-level shortwave trough moving east through the Central Plains initiated a few clusters of thunderstorms that spread into Mississippi during the morning of June 18th. With an unstable air mass and strong jet stream over the region, these storms became severe and produced hail and damaging wind through the morning. An additional round of severe storms developed during the evening of the 18th and into the mo…

Flash Flood · Jul 13, 2023. A significant flash flood event unfolded during the early morning hours of July 13th into the late morning and midday. A corridor of 6 to 9 inches fell, with locally higher amounts, roughly from Ackerman to Louisville to DeKalb MS. Some of the most impacted areas were across Choctaw and Winston Counties. Multiple roads were flooded, washed out or closed. Many structures were flooded as well along with stalled or s…

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 Neshoba County

If a building in Neshoba 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.
