A Pacific storm system now designated Potential Tropical Cyclone One-C is bearing down on Hawaii's Big Island, where the National Hurricane Center projects a strong tropical storm at landfall, the most serious direct hit threat the islands have faced in decades.
The National Hurricane Center upgraded the disturbance formerly known as Invest 93C on Wednesday, a formal step that allows forecasters to issue official track cones, watches, and warnings before the system fully organizes into a named storm. At the time of the upgrade, the system sat just over 1,000 miles southeast of the Big Island, FOX Weather reported, with forecast models showing strong agreement that it will intensify into a tropical storm or hurricane over the next few days.
If the system reaches tropical storm strength, it will be named Lala. Tropical Storm Watches had not yet been posted as of Wednesday but were expected either Wednesday night or Thursday morning, with impacts still more than 48 hours out. The FOX Forecast Center said the storm will likely organize into a tropical depression or tropical storm by that window.
Even a near-miss carries real danger for residents and visitors across the Hawaiian island chain. Forecasters project wave heights potentially exceeding 30 feet, a punishing wall of surf driven by a system that does not need to make direct landfall to cause serious coastal damage.
Tides across Hawaii are already running above normal. Three separate factors are stacking up: strong trade winds, the moon's current distance from Earth, and thermal expansion of ocean water that is unusually warm. Add a tropical cyclone's wind field on top of those elevated baselines, and the flooding risk climbs fast.
The National Weather Service in Honolulu and the Hawaii Emergency Management Agency are both analyzing the threat. The FOX Forecast Center urged all Hawaii residents to take two immediate steps: plan where they could go to be safe if they live in housing vulnerable to strong winds, heavy rain, or elevated tides, and stay current on guidance from local officials.
Direct tropical cyclone landfalls in Hawaii are extraordinarily rare. The last hurricane to come ashore was Category 4 Hurricane Iniki in 1992, which remains the costliest hurricane in Hawaiian history. That three-decade gap can breed complacency, and complacency in the face of a strong tropical storm aimed at populated coastline is a recipe for preventable harm.
The Big Island is the projected landfall point under the current NHC track. The official forecast calls for a strong tropical storm at the time of arrival, though the system's final intensity and precise track remain uncertain. Forecasters have not yet specified which other islands beyond the Big Island fall inside the projected cone.
Hawaii's geography makes any tropical system especially dangerous. The islands' steep volcanic terrain can wring enormous rainfall totals out of even modest storms, triggering flash floods and landslides with little warning. A 2021 storm system that struck the islands dumped up to 40 inches of rain on south- and southwest-facing mountainsides and forced flood watches across every Hawaiian island, and that event arrived without a tropical cyclone's concentrated wind field.
One-C is not the only system on the board. A second disturbance elsewhere in the Pacific basin carries development odds currently rated in the "high" category, though details on its location, projected track, and potential threat remain limited. Multiple simultaneous systems stretch forecasting resources and complicate emergency planning for island communities that have limited evacuation routes.
The NHC's formal upgrade of the system, from a generic "invest" to a potential tropical cyclone, matters for one practical reason above all others. It triggers the bureaucratic machinery that gets warnings into the hands of residents, airlines, shipping companies, and military installations across the islands. Without that designation, official watches and warnings cannot be issued, and the public communication pipeline stays shut.
That pipeline is now open. What happens next depends on how quickly the system organizes and whether the track holds steady toward the Big Island or shifts. Residents who wait for the watches to post before preparing are already behind.
Nature does not check the calendar before aiming a storm at an island chain. The people who live there shouldn't wait for permission to get ready.
