Hurricane Lowell: Kauaʻi, Oʻahu & Maui Property Damage & Claim Recovery Guide

Aloha. Lowell is the third tropical system to hit Hawaii in a single season, and for Kauaʻi and Niʻihau it was the big one: a hurricane warning, nearly a hundred-mile-an-hour gusts, rivers of brown water through Wainiha and Kapahi, and an island almost entirely without power. Oʻahu took the tropical-storm edge of it across the Leeward and Windward coasts, and on Maui the ocean came over the road in Kīhei, Māʻalaea and Lahaina while the uplands took 80 mph gusts. Wherever you are, the questions are the same: what do I do first, what does my insurance actually cover, and how do I make sure I recover everything — not just what the first adjuster puts on a clipboard. This guide answers those in order.

Island by Island: What Lowell Did

Lowell exploded from a tropical storm to a Category 5 hurricane over open water between September 1 and 2, then bent north toward the western islands. It passed west of Niʻihau and Kauaʻi overnight September 7–8 as a Category 2 storm with 110 mph sustained winds. The National Weather Service issued Hawaii’s first-ever tornado watch for Kauaʻi and Niʻihau. By Tuesday morning the warnings were cancelled, but flood watches, high-surf warnings and a statewide brown-water advisory remained.

First: People, Then Property

Follow official emergency guidance first. Stay off flooded roads and away from downed lines, which killed people after Lala. Treat the shoreline as closed: surf and rip currents stay life-threatening for days, and the Department of Health advises staying out of brown water for 48 to 72 hours after the rain stops. On Kauaʻi, limit water use to essentials while the county asks you to, and store the recommended gallon per person per day. Check on kupuna and neighbors when it is safe.

The First 72 Hours After Lowell

The full playbook is in our First 72 Hours guide. Here is the Lowell version, in order:

1. Wait for the all-clear, then walk the property in daylight. Look up first: roofs, ridge caps, flashing, solar mounts, gutters. Then lanai, fences, carports, ag structures, vehicles, boats.
2. Photograph and video everything before you touch it. Wide, medium, close-up, then the evidence — water lines on walls, the direction debris fell, where water came in. Inside the refrigerator and freezer too.
3. Make only temporary repairs — tarp, board, move belongings out of the wet. Your policy requires reasonable mitigation, and mitigation costs are usually reimbursable. Keep every receipt, including generator fuel, ice and tarps.
4. Don’t throw anything away yet. Damaged materials and contents are evidence. If you must clear them for safety, photograph and stage them first.
5. Report the claim promptly, facts only. Date, time, what you observed. Do not guess whether it was wind, wind-driven rain, surge or rising water — that classification decides the claim (next section).
6. Start a claim diary today. Every call, name, claim number and promise, in writing.

Wind, Rain, Surge or Flood: The Classification That Decides Lowell Claims

Lowell delivered all four at once, and each is paid — or excluded — by a different part of your insurance:

• Wind damage (lifted roofing, blown siding, collapsed lanai, tree strikes) and rain entering through wind-created openings are generally covered by your hurricane policy or rider. In Hawaii, hurricane coverage has commonly been separate from the base homeowners policy since Iniki, and the hurricane deductible is often a percentage of your dwelling limit. Our hurricane deductible guide shows you how to find your real number.
• Storm surge and rising water — the flooding in Wainiha, Kapahi and Hanalei, the surge that took the Waimea Pier and the Hanapēpē Bay road, the sand across Farrington Highway, the ocean in the Mākaha cabanas and over South Kīhei Road — is generally classified as flood: excluded from homeowners and hurricane policies, and covered only by separate flood insurance, usually NFIP.
• Mudflow and landslides are usually treated as flood or earth movement. Wet-soil tree failures that hit a structure are usually wind. The evidence on the ground decides which.

When wind and water arrive together, the classification your file receives can be the difference between a claim paid well, paid poorly or denied. The Hawaii Insurance Commissioner’s August memorandum on Lala claims told insurers to evaluate each claim on its own facts, apply the policy language as written, not lean on the storm’s classification alone, and clearly explain any denial. Expect the same standard for Lowell, and hold your carrier to it. Describe what you observed, document the physical evidence — wind-created openings, water lines, the direction of damage — and let a professional assign the cause.

Power Outages: Food Spoilage, Generators and Living Elsewhere

With KIUC warning members to expect an extended outage, the losses that follow are real money for an island family:

• Food spoilage. Many Hawaii homeowners and renters policies include refrigerated-property coverage, usually with a modest sub-limit and conditions on the cause of the outage. Photograph the contents, list every item with a rough value, then dispose of it safely. Replacement grocery receipts help establish values.
• Generators, fuel and ice. Depending on your policy these may be recoverable as mitigation or additional living expense. Keep the receipts either way.
• Additional living expense (ALE). If your home is unsafe or uninhabitable because of covered damage, your policy may pay for a place to stay, extra food costs and extra mileage. Save every receipt and note every night away.
• Renters and condo owners: renters policies cover your contents and ALE; condo owners should notify both the AOAO (for the building) and their own HO-6 carrier (for interiors and contents).

Business Owners: Closures, Spoiled Stock and Lost Income

For Kauaʻi’s visitor economy — and every restaurant, farm, shop and tour operator from Hanalei to Poʻipū, Waiʻanae to Hāna — the building is often the smaller half of the loss. Līhuʻe Airport closed for a day, Nāwiliwili Harbor and the barge schedule stalled, parks and trails closed, Front Street and the Kīhei shoreline roads shut, Kaumualiʻi Highway buried. Add Kekaha’s farms and shrimp ponds under salt water and the visitor economy running on generators. Review your commercial policy for:

• Business interruption / business income — income lost while covered physical damage keeps you closed. Keep clean records of normal revenue and every day of closure.
• Civil authority coverage — income lost when government orders keep customers away, even if your building is fine. Save the closure orders, road-closure notices and airport announcements that affected you.
• Perishable stock / spoilage — inventory lost to the outage. Photograph and inventory before disposal.
• Extra expense — generators, temporary space, expedited shipping to reopen. Keep every receipt.

Business interruption claims are among the most technical and most underpaid in all of insurance. If Lowell closed your doors, this is exactly the claim to have professionally managed from day one.

The Claim Itself: What to Expect in the Weeks Ahead

Your insurer assigns an adjuster, an inspection happens (read our inspection guide first), an estimate arrives, and a first check may follow. Three reminders for catastrophe claims specifically:

• First offers after catastrophes run low. Rushed inspections and mainland pricing databases miss island reality — barge freight, single-wall construction, Kauaʻi’s contractor shortage. Estimates are negotiable and supplements are normal.
• Depositing a routine check usually doesn’t close your claim — but read the wording. Our insurance check guide covers what to look for.
• Hidden damage surfaces for months. Wet decking under lifted shingles, moisture in wall cavities, mold in Hawaii humidity, salt corrosion after surge. Keep documenting and keep supplementing. Our Damage Iceberg guide shows exactly what inspections find below the waterline.

The money the carrier never offers is money you never see. That is the hidden cost of handling a hurricane claim alone.

The Hidden Cost of Handling It Yourself

Most property owners who manage their own storm claim believe they are saving money. Here is what actually happens: the carrier’s adjuster inspects, the carrier’s estimating software prices the scope, and the carrier’s letter explains what it will pay. Every step is built and controlled by the party that writes the check. Owners take the number, deposit it, and never learn what a complete, code-referenced, Hawaii-priced claim would have been worth. Nobody sends a letter for the depreciation that was never released, the underlayment that was never scoped, the code upgrades that were never mentioned, or the business income that was never claimed.

What our experience in Hawaii looks like. Across the claims our team has handled here, the represented outcome has consistently been higher than the carrier’s opening position — sometimes modestly, sometimes dramatically. We have taken claims that opened with an offer near $50,000 to settlements above $600,000, because the first inspection missed most of the loss. Those are real past results, not a promise for yours; they are what happens when someone who reads policies for a living builds the claim from the start.

What the research says. A 2010 Florida legislative study (OPPAGA Report 10-06) of Citizens Property Insurance claims found that policyholders who used public adjusters received substantially larger payments — the widely cited figures are 574% higher on typical claims and 747% higher on 2005 hurricane claims — though their claims took longer to settle. Florida is a different market, but the pattern is the same one we see in Hawaii: the carrier’s first number is rarely the claim’s real value.

Why the gap exists. Not because adjusters are villains — most are decent people with 200 files and a mainland price list. The gap exists because a complete claim requires a thorough inspection (roof, attic, moisture readings, every elevation), a line-item estimate priced for Hawaii, the policy read clause by clause for coverage the carrier does not volunteer, and someone who pushes back when the answer is slow, low or no. That is the job of a licensed public adjuster: your adjuster, working only for you. We look out for your recovery, not the insurance company’s bottom line.

When to Bring Us In

Either way, the first step is the same and it costs nothing: send us what you have — even phone photos and a screenshot of your declarations page — and our licensed Hawaii team will review your damage, your policy and your options. If your claim is one you can handle yourself, we will tell you exactly that.

Free State & County Recovery Programs

Alongside your insurance claim, use every official program you qualify for. Governor Green’s September 3 emergency proclamation (in effect through November 1) activated the National Guard, the Major Disaster Fund and streamlined permitting; a federal declaration for Lowell had not been announced when this guide was published, so watch the links below.

File your county damage report as soon as you safely can — it is separate from your insurance claim, and the totals help unlock federal aid for your island.
