How Vermilion Parish floods

Flash flooding from summer thunderstorms dominates the flood risk profile in Vermilion Parish, accounting for 26 of the 35 recorded flood events over the last 30 years, alongside events from floods, storm surges, tropical storms, and coastal flooding. Recent events include heavy rain and thunderstorms caused by a stalled low pressure system and cold front in May 2025, and Tropical Storm Francine in September 2024.

National Flood Insurance Program records show significant impacts across multiple zones. Properties in Zone A account for the vast majority with 3,601 claims averaging a $42,125 payout and an average recorded water depth of 7 inches. Zone X properties recorded 333 claims with an average payout of $59,352 and an average water depth of 7 inches, while Zone V properties recorded 211 claims with an average payout of $40,274 and an average water depth of 11 inches.

Homeowners in Zone A, Zone V, and Zone X should pay the closest attention to this flood risk, given the high volume of historical claims and recorded water depths associated with these areas.

From the storm reports

Flash Flood · Mar 29, 2025. A series of upper disturbances and a slow moving cold front created multiple days of stormy weather across portions of Louisiana. Severe weather and flooding occurred.

Flash Flood · May 7, 2025. A warm front slowly lifted north across the region during the 6th causing rain and thunderstorms. A low pressure system and associated cold front slowly pushed back across the area on the 7th and stalled into the 9th with a couple rounds of heavy rain and thunderstorms.

Storm Surge/Tide · Jun 19, 2024. Tropical Storm Alberto moved across the western gulf and into Northeast Mexico. The large wind field of the disorganized system pushed water levels into minor flood along the coast of Southeast Texas and South Louisiana.

Tropical Storm · Sep 11, 2024. Francine originated from a tropical wave that emerged off the West coast of Africa on August 28th. The wave traversed the tropical Atlantic Ocean with minimal organization, reaching the Leeward Islands by September 1st.

Flood insurance in Vermilion Parish

If a building in Vermilion 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.
