Hawaii Governor Josh Green activated the National Guard this week as a powerful Kona low storm system drove flash flooding across multiple islands, forcing mass evacuations, threatening aging infrastructure, and prompting what officials called the worst flooding the state has experienced in more than 20 years. The emergency, which has escalated through four successive state proclamations since early March 2026, has tested every level of government response from Honolulu to Maui County and left residents in some of the most flood-prone communities scrambling for safety.
Statewide Emergency Proclamations Escalate
Governor Green issued an emergency proclamation ahead of the Kona low, citing heavy rain, widespread flooding, strong thunderstorms, and damaging winds as the primary threats. The proclamation enabled flexible deployment of state resources, including coordination with the Office of the Governor and the Hawaii Department of Defense for Guard mobilization. That initial action has since been updated multiple times. The fourth proclamation, effective March 19, 2026, remains active according to the state’s emergency management index, reflecting the storm’s persistence and the growing scope of the crisis.
The speed at which the state moved from a single proclamation to four in roughly ten days signals that early forecasts underestimated the Kona low’s duration and intensity. Each successive proclamation expanded the governor’s authority to redirect funds, waive regulatory barriers, and mobilize personnel. For residents, this means state agencies can bypass normal procurement timelines to deliver supplies, open shelters, and stage rescue equipment closer to affected communities. The practical effect is a government operating in crisis mode with fewer bureaucratic constraints, though the exact number of Guard troops deployed and their specific operational assignments have not been detailed in official records.
State officials have emphasized that the proclamations are not only about immediate lifesaving measures but also about continuity of critical services. Flooding has disrupted road access, power lines, and communications infrastructure in multiple districts. By keeping the emergency orders in place, agencies can rapidly contract for debris removal, temporary power, and emergency communications without navigating procedures designed for normal conditions. This flexibility has been particularly important on neighbor islands, where small communities may be cut off for days when primary roads are inundated or washed out.
Maui County Declares Imminent Danger
Maui County moved in parallel with the state, issuing its own emergency proclamations on March 10 and again on March 19, 2026, according to the county’s official declarations. The second proclamation specifically referenced the National Weather Service Flood Watch and determined that the Kona storm posed imminent danger to life and property. That document grants county officials broad powers including mobilization of local resources, authority to issue alerts and warnings, and the ability to order evacuations.
The county-level action matters because Hawaii’s geography creates distinct flood risks on each island. Maui’s narrow valleys and steep terrain can funnel rainfall into sudden, violent flash floods that overwhelm drainage systems built for normal conditions. By declaring imminent danger, county officials gained legal authority to act without waiting for state-level approvals, a critical distinction when floodwaters can rise in minutes. The March 19 proclamation also enumerated specific emergency powers that go beyond what routine weather advisories allow, including the ability to commandeer private resources if necessary for public safety.
On Maui, the storm has arrived less than two years after the devastating wildfires that destroyed large portions of Lahaina and displaced thousands. County and state agencies that were already stretched by long-term recovery now face overlapping crises. The Office of Homeland Security’s Maui-focused programs have been working to coordinate preparedness and resilience projects; those efforts are now being tested in real time as emergency managers juggle flood evacuations, sheltering needs, and ongoing recovery work in communities still rebuilding from fire.
230 Rescued as Dam Failure Looms
The human toll of the flooding became clear as rescue teams pulled 230 people from floodwaters, according to Associated Press reporting. Evacuation orders went out for communities north of Honolulu after officials warned that Wahiawa Dam, a 120-year-old structure, could fail under the sustained pressure of rising water levels. A breach of that dam would send a wall of water through downstream neighborhoods, turning an already severe emergency into a catastrophe.
The Wahiawa Dam warning exposes a vulnerability that extends well beyond this single storm. Hawaii’s dam infrastructure includes structures built in the plantation era, many of which were designed for agricultural water storage rather than modern flood control. When a storm system like the Kona low parks over the islands for days, these aging structures face loads they were never engineered to handle. The fact that a dam older than commercial aviation is still a critical piece of flood infrastructure on Oahu raises hard questions about deferred maintenance and capital investment that state and county officials will face long after this storm passes.
Oversight of these facilities falls in part to agencies such as the state’s Office of Water Resources, which is responsible for regulating dams and reservoirs. Recent events have underscored the need for updated hazard assessments, revised emergency action plans, and, in some cases, costly structural upgrades. The near-crisis at Wahiawa has renewed calls from engineers and community advocates for a comprehensive review of high-risk dams statewide, including clear evacuation mapping and communication strategies for downstream residents.
Park Closures and Public Safety Measures
The emergency response extended beyond evacuations and rescues. The Hawaii Department of Land and Natural Resources closed state parks on Kauai and Oahu as a precautionary measure, issuing public safety guidance to keep visitors and residents away from trails, waterfalls, and coastal areas where flash flooding and landslides posed the greatest risk. These closures affect both local recreation and Hawaii’s tourism economy, though the immediate priority was preventing additional rescue situations in remote terrain.
Officials have urged residents and visitors to heed barricades and closure signs, noting that fast-moving water can undercut riverbanks, destabilize slopes, and sweep away vehicles in seconds. Even after rainfall subsides, saturated ground can continue to produce landslides and rockfalls. Emergency managers say avoiding unnecessary travel into vulnerable areas is one of the most effective ways the public can reduce the burden on first responders already stretched thin by water rescues and medical calls.
Strain on Vulnerable Residents and Housing
The storm’s impacts are falling hardest on residents who were already living on the edge. For people experiencing homelessness or precarious housing, floodwaters can erase what little stability they have. State programs coordinated through the Hawaii Interagency Council on Homelessness are facing heightened demand as outreach teams work to move people out of encampments near streams, canals, and low-lying coastal zones that are especially prone to rapid flooding.
Emergency shelters are juggling an influx of evacuees alongside those who lacked stable housing before the storm. Housing resources available through Hale Hawaii are being leveraged to connect displaced families with temporary accommodations, rental assistance, and longer-term placement options where possible. But advocates warn that the underlying shortage of affordable housing limits how quickly people can move from emergency cots to permanent homes, raising concerns about prolonged displacement once the immediate flood threat recedes.
Social service providers also point out that repeated disasters can compound trauma, particularly for children, kupuna, and those who survived previous events such as the Maui wildfires. Mental health support, case management, and culturally informed outreach are being woven into the emergency response, though staffing and funding constraints remain a challenge. Community organizations have stepped in with volunteer networks to deliver food, clothing, and basic supplies to families sheltering in place or staying with relatives.
Information Access and Long-Term Questions
Throughout the crisis, officials have stressed the importance of staying informed through trusted channels. The state’s eHawaii portal serves as a central gateway for residents seeking emergency information, road closure updates, and links to county alert systems. Local civil defense agencies and weather services continue to issue real-time warnings via text, radio, and social media, urging people in flood-prone areas to be ready to move quickly if conditions deteriorate.
As the Kona low slowly weakens and floodwaters begin to recede, attention is already turning to what this event reveals about Hawaii’s readiness for a future of more frequent and intense storms. The rapid escalation of emergency proclamations, the near-failure of a century-old dam, and the strain on housing and social services all point to systemic vulnerabilities. State and county leaders will face mounting pressure to invest in resilient infrastructure, modernize drainage and dam safety systems, and expand support for residents who have the least ability to recover on their own.
For now, the focus remains on keeping people safe, restoring essential services, and accounting for the damage. But as communities dry out and begin the long process of repair, the questions raised by this storm, about climate risk, infrastructure, and equity, are unlikely to fade with the floodwaters.
