Category one Hurricane Lala skirted Hawaii's Big Island over the weekend without making landfall, but its rainfall - up to 32 inches in some locations - triggered flash floods and mudslides that swept more than 100 properties from their foundations, according to Governor Josh Green. One person died in a vehicle accident tied to the storm. More than 200,000 households lost power at peak, and the storm has since weakened to a tropical storm tracking west of the islands, though tropical storm warnings remained in effect across all eight major islands as of Sunday.
Insurance Business had flagged the risk of this outcome before Lala arrived, noting that rainfall-driven landslide and mudflow damage typically falls outside standard homeowners coverage and depends instead on National Flood Insurance Program policies or surplus lines placements - meaning a storm that never makes landfall can still generate a meaningful, fragmented claims picture. Lala has confirmed that analysis.
Hawaii's insurance structure is unlike any other state in the US, and the reason traces directly to Hurricane Iniki in September 1992. Iniki was a category four storm that killed six people, injured around 100 more, and caused roughly $3 billion in damage after making landfall on Kauai - at the time the costliest hurricane to hit Hawaii in the modern era. The losses were severe enough that insurers pulled back from the state in significant numbers, prompting Hawaii to establish the Hawaii Hurricane Relief Fund to stabilise what remained of the residential property market.
The practical legacy of that exit is a market where hurricane wind coverage, flood coverage and standard property coverage function as effectively separate products with different carriers, different triggers, different deductibles and different claims processes. A homeowner hit by Lala this weekend may need to navigate all three simultaneously - and may find that the gaps between them are precisely where the most significant damage falls.
Zephyr Insurance, one of Hawaii's specialist carriers, activated hurricane coverage for Big Island policyholders ahead of Lala's approach and issued a direct reminder to customers: standard homeowners policies exclude both hurricane wind and flood damage; flood losses fall to NFIP or private flood policies; and vehicle damage requires separate comprehensive auto coverage. That the carrier felt the need to send that reminder at all is itself a measure of how frequently Hawaii policyholders misunderstand what they actually have.
Lala's flooding lands on a Hawaii property insurance market that was already stretched before the storm. The 2023 Maui wildfires destroyed more than 2,200 structures, drove insured losses past $3.2 billion, and accelerated a conversation about whether the state's insurance market was structurally capable of absorbing repeated climate-driven disasters. A report from the Insurance Fairness Project earlier this year warned that hundreds of thousands of properties across Hawaii do not currently qualify for flood insurance at all - in a state where rainfall-driven damage, rather than direct hurricane landfall, has historically been the more consistent claims driver.
Catastrophe modelers typically wait until a storm's final track and intensity are confirmed before publishing loss estimates, and no formal figure has been released for Lala as of this writing. Hawaii's ILS and catastrophe bond structures are generally built to protect against more intense, higher-category storms - meaning a category one system like Lala is unlikely to trigger reinsurance or cat bond recoveries even though it has caused significant localised damage. That dynamic mirrors the outcomes from Hurricane Lane in 2018 and Hurricane Hone in 2024, both of which caused meaningful flood and wind damage in Hawaii without making landfall.
For adjusters working Lala claims, the fragmentation of Hawaii's insurance structure is the central practical challenge. Flood claims will need to be filed separately from wind or homeowners claims, and many policyholders will arrive at that conversation without understanding which policy covers which loss type. Expect that explanation to be needed repeatedly.
For brokers serving Hawaii clients, Lala is a direct prompt to review flood coverage across the book. Most of this storm's damage came from rain rather than wind - and Hawaii's own claims history shows that pattern is more the rule than the exception for storms approaching the islands. Clients outside FEMA-designated Special Flood Hazard Areas who have never purchased flood coverage may have made that decision based on their map classification rather than their actual rainfall and runoff exposure. Private flood products from surplus lines carriers are available in Hawaii alongside NFIP policies, giving brokers options beyond the federal programme for clients who want higher limits or broader terms than the NFIP provides. The conversation is overdue for any Hawaii property client whose flood coverage status has not been reviewed since the Maui wildfires changed the market's risk calculus.
