Hurricane Lowell Lashes Hawaii's Western Islands as Third Major Storm in Three Weeks

Hurricane Lowell, a Category 3 storm with sustained winds of 125 mph, swept past the Hawaiian islands of Kaua'i and Ni'ihau on September 7 and 8, 2026, under a statewide emergency declaration, knocking out power and forcing school closures across Kaua'i, Ni'ihau and O'ahu. It was the third major storm in just over three weeks to target Hawaii, a punishing rhythm that forecasters tied to an El Nino pattern supercharging the Pacific hurricane season.

The 2026 season has put Hawaii in an unusual position. Tropical cyclones are not rare in the central Pacific, but three significant systems in three weeks have forced the state to operate in a near-constant state of alert. Each storm has followed a different track and brought its own mix of threats, yet the cumulative effect has been much the same: schools shut, power flickering, roads flooding, and emergency crews moving from one island to the next before the previous storm has fully cleared.

Lowell's arrival followed days of forecasts that carried both reassurance and warning. The storm's center was expected to remain offshore, passing west of the island chain rather than crossing directly over it. But forecasters were blunt that Hawaii did not need a direct hit to feel the storm. Waves, wind and rain would arrive well ahead of the center, and the ground beneath the western islands had already been tested by earlier systems in the season.

Key Facts

CNN reported on September 6 that Lowell was a Category 3 hurricane with 125 mph winds and that it was the third storm in just over three weeks to target Hawaii as El Nino supercharged the Pacific hurricane season.

CNN reported on September 6 that Hawaii Gov. Josh Green had declared a statewide emergency, activated the Hawaii National Guard and deployed six high-water vehicles to Kaua'i as the state braced for the storm's approach.

CNN reported on September 6 that the storm's center was forecast to pass about 130 miles west of Ni'ihau and about 170 miles west of Kaua'i late on September 7 into September 8, with waves of up to 14 feet and 4 to 6 inches of rain expected across the western islands.

ABC News reported on September 7 that destructive wind gusts topped 90 mph and that Lowell had triggered Hawaii's first-ever tornado watch, a striking measure of the storm's intensity and reach even with its center offshore.

USA Today reported on September 8 that a hurricane warning remained in effect for Kaua'i County as rains from Lowell drove flash flooding across parts of the island.

The Weather Channel reported on September 8 that the storm's core had passed just north of Kaua'i, leaving lingering winds, rain and pounding surf behind. Kauai Now reported on September 8 that the western islands were beginning to deal with the aftermath as the system finally pulled away to the northwest.

Taken together, the reports describe a storm that did not need to make landfall to leave a mark. The numbers tell the story: winds near the center reached 125 mph, gusts on land topped 90 mph, waves were forecast to reach 14 feet, and rain totals of 4 to 6 inches were expected to fall on islands that had seen little time to dry out between storms. A track that kept the center roughly 130 to 170 miles offshore still produced a statewide emergency, a hurricane warning for Kaua'i County, the activation of the National Guard and the first tornado watch ever issued in Hawaii.

Analysis

The bigger picture here is that Hawaii is in the middle of a season that looks very different from the one its emergency plans were built around. Three major storms in just over three weeks is not simply bad luck; it is the signature of an El Nino pattern that has given the Pacific hurricane season an unusual amount of energy. When the ocean and atmosphere settle into that configuration, the central Pacific tends to sit in a more favorable position for tropical cyclone formation and intensification, and the islands have been catching storms that in a quieter year might have stayed far to the south or died out before reaching land.

What this really means is that officials are now making decisions under a new set of expectations. Gov. Josh Green's choice to declare a statewide emergency, activate the Hawaii National Guard and send six high-water vehicles to Kaua'i before Lowell arrived tells you how seriously the state took a storm whose center was forecast to remain offshore. That kind of preparation is expensive and disruptive. It closes schools, mobilizes troops and ties up resources. But the alternative, waiting to see whether a storm will turn at the last moment, is exactly what leaves communities exposed when a forecast cone shifts east by even a few dozen miles.

There is also a quieter signal in the response. The school closures that stretched across Kaua'i, Ni'ihau and O'ahu were ordered not only for the storm itself but for the conditions that a near miss can still produce: falling trees, flooded roads, power lines brought down by gusts of 90 mph or more. Emergency managers have learned that the most dangerous hours of a hurricane often come after the headline wind number has moved on, and the decisions made on September 6 and September 7 reflected that lesson. The state was not reacting to Lowell in isolation; it was reacting to Lowell as the third storm in a row, with all the exhaustion and accumulated risk that implies.

Why It Matters

Hurricane Lowell matters because it shows how thin the margin can be between a close call and a catastrophe for an island chain. The forecast track kept the center roughly 130 to 170 miles offshore, and yet a hurricane warning covered Kaua'i County, the state called up the National Guard, power went out and schools closed. A track even slightly farther east could have produced a far more damaging scenario. The fact that so many impacts occurred without a direct hit is a warning about what the next storm might do if its path bends the other way.

The storm also matters for what it says about the season as a whole. Three major storms in three weeks has strained the usual disaster cycle, in which communities respond, recover and then prepare for the next event. When storms arrive in quick succession, recovery is cut short and preparation begins from a weaker position. The pre-positioning of six high-water vehicles on Kaua'i and the standing activation of the Hawaii National Guard suggest that state leaders are now planning for a season in which storms arrive in clusters rather than as isolated events.

For the broader Pacific, Lowell is another data point in a season that El Nino has reshaped. Islands that sit far from the busiest hurricane corridors have found themselves in the crosshairs repeatedly, and each pass raises the same question about how communities harden themselves against a hazard that is arriving more often. The emergency declaration that Gov. Josh Green signed was a statewide one, covering islands beyond the storm's immediate path, and that breadth is itself a recognition that the whole chain now shares a common exposure.

Next Up

With the storm's core now passing just north of Kaua'i, the immediate focus is on the hazards Lowell leaves behind. The Weather Channel reported on September 8 that lingering winds, rain and pounding surf were expected to persist across the western islands, and USA Today reported on September 8 that flash flooding remained a live threat in Kaua'i County, where the hurricane warning had not yet been lifted. The cleanup from a storm can take days even when the sky has cleared, and the ground soaked by 4 to 6 inches of rain will stay unstable until it has time to drain.

The end of Lowell will not necessarily mean the end of the threat. The same El Nino conditions that produced three major storms in three weeks remain in place across the Pacific, and forecasters will be watching for any new disturbances that could organize along a similar path. State officials, already operating under a statewide emergency declaration, are likely to keep response resources in place until the season shows clearer signs of quieting, and communities that have been through three storms in a month will be watching the same maps.

For Kaua'i, Ni'ihau and O'ahu, the coming days are about recovery and about counting the cost of a storm that knocked out power and closed schools without ever crossing the coastline. For the rest of the Pacific hurricane season, Lowell is a reminder that the next storm may already be taking shape, and that preparation is measured not in whether a warning is issued but in how much time communities have between them.
