A Category 2 hurricane raked Hawaii’s westernmost inhabited islands overnight, sending sustained winds of 110 mph across Niihau and pushing a hurricane warning over all of Kauai County. Lowell’s center tracked just west of Niihau as the storm closed the final stretch of open ocean between it and the island chain, arriving with heavy rain, damaging gusts and seas the National Weather Service put at 20 to 45 feet. Oahu, roughly 190 miles to the east, stayed under a tropical storm warning rather than a hurricane warning as forecasters watched the storm’s exact path. The event marked one of the more direct hurricane encounters the state has faced in years, with wind and surf effects reaching far beyond the immediate track of the storm’s center.
Advisory 49 Pins Down the Storm’s Strength
The National Hurricane Center’s overnight bulletin, Advisory 49, listed maximum sustained winds at 110 mph with higher gusts, a Category 2 reading on the five-step hurricane scale. Aircraft reconnaissance measured a minimum central pressure of 963 millibars, or 28.44 inches of mercury, a depth that typically accompanies a compact but potent storm core. At 11 p.m. Hawaii Standard Time on September 7, the center was fixed near 21.9 degrees north and 160.8 degrees west, about 90 miles west of Lihue on Kauai and 190 miles west-northwest of Honolulu.
The National Hurricane Center advisory described the setup as a hurricane passing dangerously close to Niihau before curving away from the main island chain, a track that kept the most damaging quadrant of the storm bearing down on the two westernmost counties rather than sweeping across Oahu or Maui. A central pressure reading in the low 960s millibar range is a standard way meteorologists gauge a storm’s intensity independent of the wind estimate, and the two measurements together painted a consistent picture of a strong, compact Category 2 system rather than a weakening one.
Hurricane and Tropical Storm Warnings Span the Islands
Kauai County, which includes both Kauai and Niihau, was placed under a full hurricane warning, the strongest advisory the weather service issues short of an extreme wind warning. Oahu carried a tropical storm warning, reflecting forecasts for weaker but still hazardous winds as Lowell’s outer bands reached the more populated island. The split reflected how tightly wound the storm’s core remained even as its overall forward speed slowed while approaching the archipelago.
A hurricane warning of this kind triggers a standard set of local responses in Hawaii, including school and government office closures, the activation of emergency shelters and advisories urging residents in flood-prone and coastal areas to move to higher ground before conditions deteriorate. Because Kauai sits farthest west among the state’s populated counties, it typically receives the least lead time of any island when a storm approaches from the south or southwest, leaving emergency managers a narrower window to finish preparations once a hurricane warning is issued.
Barking Sands Reports the First Direct Wind Impacts
A weather station at Barking Sands on western Kauai, known in aviation circles as PHBK, recorded sustained winds of 51 mph with a gust to 84 mph as Lowell’s outer bands arrived. That reading, taken from one of the few instrumented sites on the island’s exposed west shore, gave forecasters an early, real-world confirmation that the storm’s wind field extended well ahead of its center rather than staying confined to the immediate eyewall. The station sits on a stretch of coastline with little topographic shielding, which typically makes it one of the first places on Kauai to register a storm’s leading winds before they reach more sheltered inland communities.
Niihau Faces the Region’s Highest Wind Forecast
The National Weather Service office in Honolulu forecast peak winds of 75 to 95 mph for Puuwai, the small settlement on Niihau, with gusts reaching as high as 160 mph as the eyewall passed closest to the privately owned island. That forecast, carried in a National Weather Service alert, made Niihau the single location expected to take the most direct hit from Lowell’s core, ahead of any other point in the state. Niihau is one of Hawaii’s least populated and least developed islands, privately owned and largely closed to outside visitors, factors that limit the number of structures and residents directly exposed even as the wind forecast there ran higher than anywhere else in the state.
Kauai’s History With Direct Hurricane Strikes
Kauai has been struck directly by a major hurricane before. Hurricane Iniki came ashore on the island in September 1992 as a Category 4 storm, killing several people and destroying thousands of homes in what remains the most damaging hurricane to hit Hawaii in the modern record. Lowell’s Category 2 winds were considerably weaker than Iniki’s, and its center passed offshore of Niihau rather than making a direct landfall on Kauai itself, but the comparison is part of why emergency officials in the county treat any hurricane-strength system approaching from the south or west with particular caution.
Power Losses Spread Across Kauai County
Local outlets reported that most of Kauai County lost electricity as Lowell’s hurricane-force gusts reached the island, with utility crews unable to begin repairs until winds eased enough for safe access to damaged lines. Coastal flooding from the large surf compounded the wind damage in low-lying areas, and county officials urged residents to stay off flooded and debris-strewn roads while the storm’s core continued moving away from the islands. The National Weather Service noted that a few tornadoes remained possible across the Hawaiian Islands as Lowell’s outer bands rotated through, a secondary hazard layered on top of the hurricane winds and surf. Agricultural operations on Kauai’s western side, along with the island’s tourism-dependent hotels and vacation rentals, were among the first sectors expected to report damage assessments once road access improved.
