On May 26, 2026 — three days ago — Moody's published a nationwide flood risk analysis that put a specific number on a problem Louisiana homeowners have lived with for decades: the United States is carrying between $375 billion and more than $1 trillion in uninsured residential flood exposure. Louisiana is named as one of four states — alongside Florida, South Carolina, and Texas — at the center of that gap.
Hurricane season opened June 1. And more than 52,000 Louisiana residents have dropped their flood insurance in recent years — moving in exactly the wrong direction.
This is not an abstract risk-modeling problem. It is a practical reality for hundreds of thousands of Louisiana homeowners who believe their standard homeowners insurance policy covers flooding. It almost certainly does not. And the gap between what they think they have and what they actually have could cost them everything in a bad storm season.
Here is what is happening, why it is getting worse, and what you can do about it before peak hurricane season arrives.

The Core Problem: Your Homeowners Policy Does Not Cover Floods
This is the most important sentence in this article, so it is worth stating plainly: standard homeowners insurance in Louisiana — and in every other state — does not cover flood damage. Not storm surge. Not rising water from a hurricane. Not flash flooding from extreme rainfall. None of it.
Flooding requires a separate policy. The primary source of that coverage in Louisiana is the National Flood Insurance Program (NFIP), administered by FEMA. As of 2026, Louisiana has approximately 500,000 active NFIP policies — making it one of the most NFIP-dependent states in the country.
But that number has been shrinking. About 70,000 NFIP policies were dropped in Louisiana between 2022 and 2024 — a direct consequence of FEMA's Risk Rating 2.0 pricing overhaul pushing costs out of reach for many households. Jefferson and Orleans parishes, which account for roughly 40% of the state's total repeat flood claims, have been hit especially hard by premium increases.

What Risk Rating 2.0 Changed — and Why It Drove People Off Flood Insurance
Before 2021, NFIP premiums were calculated primarily based on a property's flood zone designation on FEMA maps. If your property was outside a high-risk zone on the map, your rate was relatively low regardless of your actual exposure.
In 2021, FEMA launched Risk Rating 2.0, which overhauled that methodology. Under the new system, premiums are based on individual property characteristics — including distance to water, foundation type, elevation, and the frequency and cost of flood events at that specific location — rather than just the flood zone on a map.
The intent was to price flood risk more accurately. The outcome for many Louisiana properties was a sharp premium increase. In Jefferson and Orleans parishes, premiums doubled for many policyholders. FEMA caps annual increases at 18% for existing policies, meaning some homeowners are still mid-transition to their full-risk rate.
For lower- and middle-income households, those increases were unaffordable. Many simply dropped their policies. The result is a growing population of Louisiana homeowners who face genuine, uninsured flood exposure — exactly the homes that will face the worst financial consequences in a major storm event.

What the Moody's Report Actually Says About Louisiana
The Moody's RMS analysis published May 26 modeled three flood scenarios: a standard 1-in-100-year flood event, an extreme 1-in-500-year flood, and a 2050 climate scenario incorporating sea-level rise and intensifying precipitation.
The headline number: the U.S. carries a $375 billion flood protection gap in a 1-in-100-year event — rising to over $1 trillion in an extreme scenario. Louisiana sits at the center of that national exposure alongside Florida, South Carolina, and Texas.
The report also highlights a critical limitation of FEMA's flood maps: they are primarily based on riverine flooding patterns and do not adequately account for storm surge, extreme rainfall events, or future sea-level rise. That means many Louisiana properties carry significant flood risk that is not reflected in their flood zone designation — and homeowners relying on their zone designation to decide whether they need flood insurance may be making a dangerous miscalculation.
The NFIP's $250,000 maximum building coverage cap for a single-family home is another structural gap. For Louisiana homeowners whose properties have appreciated significantly since they purchased their policies, or whose homes are in higher-value areas, that cap may not be sufficient to rebuild after a major flood event.

What NFIP Covers — and What It Doesn't
Understanding what the NFIP does and does not cover is essential to knowing whether you have a gap.
NFIP covers: physical damage to your building structure caused by flooding, up to $250,000 for the building and $100,000 for contents under a separate contents policy. It also covers essential systems — electrical, plumbing, HVAC — and permanently installed appliances.
NFIP does not cover: temporary living expenses while your home is being repaired, business interruption, damage from moisture or mold if you did not act promptly to mitigate it, landscaping, decks, patios, vehicles, or most belongings in a basement.
Storm surge — the wall of ocean water that a hurricane pushes inland — is covered by NFIP as flooding. But the timing and documentation of your claim matters. Insurers and FEMA claims adjusters will distinguish between wind damage (covered by your homeowners policy) and flood damage (covered only by NFIP). After a hurricane that produces both, disputes about which peril caused which damage are common and can delay or reduce your payout.

Private Flood Insurance: An Increasingly Important Alternative
The private flood insurance market has grown significantly since Risk Rating 2.0 reshaped NFIP pricing. For some Louisiana homeowners, private flood coverage now offers a meaningful alternative — sometimes at lower premiums, with broader coverage terms, including higher building limits above the NFIP cap and coverage for temporary living expenses that the NFIP excludes.
Private flood insurance is not available everywhere, and not all carriers write in all Louisiana parishes. But if you have been priced out of NFIP coverage or are carrying an NFIP policy that no longer covers your full replacement cost exposure, getting private flood quotes alongside your NFIP renewal is worth doing.
An important note on timing: the NFIP has a 30-day waiting period before a new policy takes effect. Most private flood policies have similar waiting periods. If a named storm is already threatening, it is too late to buy flood insurance. This is a before-hurricane-season decision, not an after-forecast decision.

A Step-by-Step Checklist: Closing Your Flood Coverage Gap
Step 1: Confirm Whether You Have a Flood Policy
This sounds obvious, but many Louisiana homeowners are genuinely uncertain. Check your insurance documents now. A homeowners policy and a flood policy are separate documents from separate programs. If you only have one policy, you likely only have homeowners coverage — not flood.
Step 2: Check Your NFIP Premium Under Risk Rating 2.0
If you have an active NFIP policy, check your current premium and compare it to what you paid three years ago. If you are mid-transition to your full-risk rate, your next renewal may be significantly higher. Budget for it — and use this as a prompt to also shop private flood alternatives.
Step 3: Review Your NFIP Coverage Limits Against Your Home's Value
The NFIP building cap is $250,000. If your home would cost more than that to rebuild at current construction costs, you have a gap. Consider an excess flood policy — private coverage that sits above your NFIP limits — to close it.
Step 4: Add Contents Coverage If You Don't Have It
NFIP building coverage and NFIP contents coverage are separate policies. Many Louisiana homeowners have the building policy but not the contents policy. Your furniture, appliances, clothing, and electronics are not covered by the building policy.
Step 5: Get Private Flood Quotes
Even if you are keeping your NFIP policy, get at least one private flood quote to compare. Private options have expanded, and you may find better terms, higher limits, or coverage for temporary living expenses that the NFIP does not provide.
Step 6: Do Not Wait for a Named Storm
The 30-day waiting period means that once a storm is in the Gulf, it is too late to buy coverage for that event. Review and purchase flood insurance now, before the peak of hurricane season in mid-September.
Step 7: Document Your Home's Contents
Regardless of which flood policy you carry, photograph or video every room of your home and store the documentation somewhere offsite — cloud storage, a relative's home outside the flood zone. Claims adjusters require documentation of what you lost. In the chaos after a flood event, this documentation is invaluable.

The Bottom Line
Louisiana's flood insurance situation in 2026 is a layered crisis: Risk Rating 2.0 drove tens of thousands of homeowners off coverage precisely when that coverage became more accurately priced for the risk they face. A Moody's analysis published this week put a number — $375 billion to $1 trillion nationally — on what that protection gap looks like at scale.
For individual Louisiana homeowners, the math is simpler: if you do not have a flood policy and your home floods, you will rebuild with your own money or not at all. Federal disaster assistance after a declared disaster is available, but it is capped, delayed, and not a substitute for insurance.
Hurricane season is open. The 30-day clock starts the moment you decide to act. For most Louisiana homeowners, that decision should have been made last month — but making it today is still better than making it after a storm is named.
