How Lawrence County floods

Flash flooding from severe thunderstorms dominates the flood profile of Lawrence County, supported by additional impacts from tropical systems. Over the last 30 years, the NOAA Storm Events Database recorded 35 flash flood events, alongside 4 tropical storms, 2 hurricanes, and 1 general flood. Recent activity includes heavy rainfall and flash flooding from training thunderstorms in January and March 2024, followed by strong winds and heavy rain as Tropical Storm Francine moved across central Mississippi in September 2024.

National Flood Insurance Program records show claims distributed across multiple zones. Properties in Zone A experienced 21 claims with an average payout of $23,267 and an average recorded water depth of 6 inches. Zone UNKNOWN recorded 15 claims averaging $8,376 with an average water depth of 3 inches, while Zone X logged 7 claims with an average payout of $49,838 and an average water depth of 4 inches.

Homeowners and real estate agents in Zone A and unmapped areas should pay the closest attention to flood risks given the frequency of flash flooding and recorded claim histories. Additionally, properties in Zone X should maintain awareness, as lower-risk zones still experience costly flood events during severe weather.

From the storm reports

Flash Flood · Oct 26, 2025. A line of thunderstorms formed west of the area and moved across Mississippi early in the morning. Some of these thunderstorms produced damaging wind gusts and heavy rainfall.

Flash Flood · Jan 24, 2024. With an upper-level trough of low pressure situated over Central Plains and a very moist air mass extending north through the Mississippi River Valley, training showers and thunderstorms produced heavy rain and flooding over parts of Mississippi.

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 · Mar 8, 2024. Training of heavy thunderstorms produced flash flooding across central Mississippi and the Interstate 20 corridor.

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.

Cross-section of a river floodplainDiagram: a river valley. The floodway is the channel and the land beside it; the 1%-annual-chance flood surface (the base flood elevation) covers the valley floor as zone A or AE; a narrow band higher up is shaded X, the 0.2% floodplain; higher ground is X.0.2% CHANCE A YEAR (500-YEAR)BASE FLOOD ELEVATION · 1% A YEARXAEFloodwayAEX
  1. A / AE Inside the 1%-a-year floodplain: about a 26% chance of flooding over a 30-year mortgage. AE has a mapped base flood elevation; plain A does not.
  2. Floodway The channel and the land beside it that has to be kept clear enough to carry the flood. Building here is tightly limited.
  3. X shaded The 0.2% (500-year) floodplain, plus some levee-protected and very shallow flood areas.
  4. X Outside both lines. No federal requirement to insure, which is not the same as no risk.

Flood insurance in Lawrence County

If a building in Lawrence 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.
