Hawaii Governor Josh Green declared a statewide emergency on March 9, 2026, as a powerful Kona low-pressure system bore down on the island chain with threats of flash flooding, damaging winds, severe thunderstorms, and summit-level snow on the Big Island. The initial proclamation, issued before the storm made its closest approach, activated state and county emergency agencies to coordinate preparations across all major islands and was detailed in a governor’s news release. A second proclamation followed days later, signaling that the threat escalated beyond initial projections and forced officials to widen their response.
Statewide Emergency Ahead of First Impact
The storm was expected to strike Kauai and Oahu first on March 9, with conditions spreading across the rest of the state through the weekend. That timeline drove the governor’s decision to act before rainfall began, a departure from the reactive posture Hawaii has sometimes taken during past Kona events. By issuing the proclamation early, the state positioned itself to unlock emergency procurement authority and direct resources through the state emergency management agency, county emergency management offices, and the National Weather Service simultaneously.
The preemptive approach matters because Kona storms, which form south or southwest of the islands rather than from the typical northeast trade-wind direction, tend to produce widespread and prolonged rainfall that overwhelms drainage infrastructure. Flash flooding is the primary killer in Hawaiian weather events, and the state’s mountainous terrain can funnel water into populated valleys within minutes. The governor’s office framed the proclamation around heavy rain and flash flooding potential statewide, but the hazard list extended well beyond water to include wind, thunderstorms, and winter conditions at high elevations.
NWS Forecast: Flooding, Wind, and Big Island Snow
The Honolulu forecast office of the National Weather Service described a hazard suite that included flash flooding, damaging winds, strong to severe thunderstorms, and snow and ice on Big Island summits. High Wind products were among the active watches, warnings, and advisories the NWS issued for the event, reflecting concern that gusts could damage structures and knock out power across multiple counties.
That combination of hazards is what separates a serious Kona low from routine winter rain. Wind-driven rain penetrates buildings differently than vertical rainfall, and saturated soil loosens root systems that hold trees upright during gusts. When both hazards arrive together, the risk of downed power lines, blocked roads, and cascading infrastructure failures rises sharply. Snow and ice on the summits of Mauna Kea and Mauna Loa add a less-discussed but real danger for observatory workers, maintenance crews, and hikers who may not expect winter conditions in a tropical state, especially when visibility drops and temperatures plunge quickly.
Maui County Mobilizes Crews and Shelters
On March 10, Maui County Mayor Richard Bissen signed a separate county emergency proclamation and ordered crews into the field. Preparations included clearing drains and culverts, staging sandbags at key locations, identifying emergency shelters, and readying public works teams for rapid deployment if roads washed out or landslides occurred. The NWS had already issued a flood watch specifically for Maui County, giving Bissen legal and practical grounds to act ahead of the heaviest rainfall.
County officials encouraged residents and visitors alike to stay informed and prepare personal emergency kits with food, water, medications, and flashlights. That messaging carried extra weight on Maui, where communities are still recovering from the August 2023 wildfire disaster in Lahaina. The county’s ongoing work through Maui recovery programs means that some displaced residents remain in temporary housing that may be more vulnerable to high winds and flooding than permanent structures. A severe storm hitting Maui during an active rebuilding phase raises the stakes for both emergency managers and the families they serve, who may have fewer options if shelters fill or transportation is disrupted.
Layered Proclamations Signal Escalating Risk
The state’s disaster declaration index shows that a Second Emergency Proclamation related to the March 2026 Kona Low Weather Event was filed after the initial declaration. That sequence indicates the storm’s impacts either met or exceeded the thresholds outlined in the first proclamation, requiring expanded authority for spending, resource allocation, or regulatory waivers as conditions evolved.
Hawaii’s emergency proclamation system works in layers by design. The governor’s declaration activates state-level coordination, while county mayors issue parallel orders that unlock local resources and clarify lines of authority for police, fire, and civil defense agencies. When a second state proclamation follows, it typically extends the geographic scope, the duration, or the spending ceiling of the original, and can also adjust which statutes are suspended to speed contracting and repairs. This layered structure allows officials to scale their response without waiting for federal disaster declarations, which can take days or weeks to process. For residents, the practical effect is faster access to shelters, debris removal, and road repairs than a single-tier system would allow, particularly in remote communities that can be isolated by one washed-out bridge.
Vulnerable Populations Face Heightened Exposure
Hawaii’s statewide homelessness initiatives add a dimension that weather forecasts alone do not capture. Unsheltered individuals on every island face direct exposure to flash flooding and wind without the protection of permanent walls or elevated foundations. Emergency managers must account for encampments near streams, drainage ditches, and coastal areas that become hazardous during heavy rain, and outreach teams typically increase contact in the days before a major storm to warn people and offer transport to shelters where space is available.
The state’s housing programs, including those tracked through the central housing portal, also intersect with storm preparedness. Residents in transitional or subsidized housing may lack renter’s insurance, backup power, or the financial reserves to evacuate on short notice or replace damaged belongings. When officials urge people to “be prepared,” the advice lands differently depending on income, housing stability, access to vehicles, and proximity to flood zones or unstable slopes. A Kona storm of this magnitude tests not just infrastructure but the equity of the state’s safety net, revealing gaps where language access, disability accommodations, or transportation assistance may fall short of need.
What the Preemptive Strategy Gets Right and Where It Falls Short
Hawaii’s decision to issue emergency proclamations before the storm arrived reflects lessons learned from past events where delayed action cost lives and complicated recovery. By moving early, the governor and county mayors gave agencies time to clear critical drainage, pre-position equipment, and alert residents while skies were still relatively calm. The coordination described in the statewide announcement and mirrored in Maui County’s local order shows a system that can pivot quickly when forecasts point to a multi-hazard event.
Yet preemptive declarations are only as effective as the resources and communication that follow them. For residents without cars, savings, or stable housing, the ability to act on official guidance remains limited. Outreach to homeless encampments, translation of alerts into multiple languages, and tailored support for wildfire-displaced families on Maui are all areas where the state’s policies are still being tested. As the March 2026 Kona low plays out, the layered proclamations and advance warnings demonstrate a more proactive posture, but they also highlight the ongoing challenge of ensuring that every community, from summit observatories to coastal encampments, can weather the next severe storm with more than just a forecast in hand.
