Flash flooding from heavy rainfall events dominates the flood character of Grant Parish, supported by 44 recorded flash flood events alongside tropical storms and hurricanes over the last 30 years. Recent events documented in the NOAA database include severe flash flooding driven by slow-moving frontal boundaries and high moisture levels in April 2024, as well as repetitive thunderstorms fueled by a stationary front and moisture from Tropical Storm Rafael in November 2024.
National Flood Insurance Program records indicate that flood risks impact properties across multiple zones. Zone A accounts for the highest claim volume with 299 claims averaging an 8-inch recorded water depth and an average payout of $13,892. Zone X properties have also experienced significant impacts, recording 51 claims with an average water depth of 8 inches and the highest average payout at $28,499. Properties in zones with unknown designations and unshaded Zone X areas have recorded lower averages, including 84 claims in unknown zones averaging 3 inches of water depth and 4 claims in unshaded Zone X averaging 3 inches of water depth.
Homeowners and real estate agents in high-risk zones, particularly Zone A and Zone X, should pay close attention to these flood risks, given the documented average water depths of 8 inches and substantial historical payouts.
Summary written from NOAA storm reports and NFIP claims for this county. Not a prediction.
1% of Grant Parish’s flood insurance claims were on properties rated outside FEMA’s high-risk zones.

In flood insurance claims here that reported a flood depth, the average was 7 inches.

Flash Flood · Apr 10, 2024. A frontal boundary became stationary across the heart of the Ark-La-Tex region in vicinity of the Interstate 30 corridor on April 8th before slowly advancing southeast on April 9th. Concurrently, very moist southwest flow aloft resulting from a nearly cut-off low across the Desert Southwest provided for precipitable water values near 2 inches. Thunderstorms developed and gradually spread northward from Central…
Flash Flood · Nov 9, 2024. An upper trough slowly shifted east across the Central and Southern Plains on November 9th, behind a nearly stationary frontal boundary that extended from portions of Southeast Texas into Central and Northeast Louisiana. While the forcing ahead of the trough and along the front resulted in numerous showers and thunderstorms which moved repeatedly over the same areas of Central and Southwest Louisiana, additional m…
Hurricane (Typhoon) · Aug 27, 2020. Major Hurricane Laura tracked north northwest across the Central and Northern Gulf of Mexico from the Central Carribean Sea near Cuba, making landfall in Southwest Louisiana near Cameron around 1 am on August 27th as a strong Category 4 hurricane with maximum sustained winds near 150 mph, and a minimum central pressure of 938 mb. Laura remained a hurricane as it tracked north across Southwest and Central Louisiana…
Flash Flood · Oct 10, 2020. Hurricane Delta tracked north northwest across the Western Carribean Sea as a major hurricane, having rapidly strengthened from a tropical depression to a Category 4 hurricane in just over 36 hours, the fastest intensification rate on record. Delta made its first landfall across the Yucatan Peninsula near Cancun on October 7th, before tracking north and making a second landfall near Creole, Louisiana in Cameron Pa…

Every colour on the map above is a place on this drawing: where the ground sits relative to the flood FEMA plans for.
If a building in Grant Parish 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.
