How New Madrid County floods

New Madrid County experiences flooding primarily driven by long-duration river and general flood events rather than flash floods, based on 64 recorded flood events compared to 15 flash flood events over the last 30 years. Recent events illustrate this pattern; for example, on February 15, 2025, showers and thunderstorms produced heavy rainfall of 2 to 5 inches near the Mississippi River, causing minor flooding of city streets in New Madrid as well as numerous state highways and county roads. Additionally, a strong storm system on March 3, 2023, brought heavy rainfall of 3 to 4.5 inches that produced flash flooding of a few creeks and roads alongside minor flooding on small rivers.

National Flood Insurance Program claims data indicates that properties located in Zone A have experienced the highest volume of claims at 143, with an average payout of $18,427 and an average recorded water depth of 5 inches. However, properties in Zone X_UNSHADED have recorded substantial severity, with 17 claims averaging a payout of $38,040 and an average recorded water depth of 36 inches. Homeowners and real estate agents representing properties in Zone A and Zone X_UNSHADED should pay the most attention to flood risk due to their distinct patterns of claim frequency and recorded water depth.

From the storm reports

Flood · Feb 15, 2025. Showers and thunderstorms produced heavy rainfall (2-5) as they streamed northeast across southeast Missouri in the afternoon and evening of the 15th. The greatest rainfall amounts were near the Mississippi River in New Madrid and Mississippi counties. Minor flooding of city streets occurred in the city of New Madrid and along numerous state highways and county Roads. The heavy rain caused a retaining wall to coll…

Flash Flood · Aug 4, 2023. Scattered to numerous thunderstorms with very heavy rainfall developed over southeast Missouri during the night of the 3rd. These southeastward-moving storms gradually morphed into an area of widespread moderate rainfall with isolated embedded storms through the morning of the 4th. The heavy rainfall on the 4th coincided with areas of heavy rainfall that occurred on the morning of the 3rd. Two-day rainfall totals…

Flash Flood · Mar 3, 2023. A strong storm system led to significant impacts. Heavy rainfall amounts of 3 to 4.5 inches produced flash flooding of a few creeks and roads. Small rivers such as the Black, Current, and St. Francis experienced minor flooding. Strong wind gusts occurred, ranging between 40 and 60 mph. These winds were produced by a strong pressure gradient on the back side of a very intense low pressure system. The highest measur…

Flood · Aug 3, 2023. Northwest to southeast oriented bands of thunderstorms moved southeast, training over the same areas for several hours. A strong and very moist low-level wind flow fed the storms, with 850 mb winds generally from 35 to 40 knots. Tropical precipitable water values were estimated to be between 2 and 2.4 inches. Instability was sufficient for strong updrafts, with 1000 to 2000 J/kg of elevated cape near the confluenc…

Flood insurance in New Madrid County

If a building in New Madrid 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.
