On Thursday, Hurricane Lowell held at Category 4 strength south of Hawaii, packing sustained winds of 140 mph after an extraordinary burst of intensification. The cyclone had surged from a 70 mph tropical storm to a 160 mph Category 5 hurricane in just 36 hours — becoming the central Pacific’s first Category 5 storm since Walaka in 2018.¹

The immediate concern is not Lowell’s current position but its projected pivot. Rather than continuing west and safely out to sea, the storm is expected to turn sharply north over the weekend, potentially bringing it dangerously close to Kauai late Monday or early Tuesday. The National Hurricane Center said Lowell was “still forecast to be at or near major hurricane strength when making its closest approach to the Hawaiian Islands.”

That forecast has created a clear shared warning among meteorologists: damaging winds, life-threatening surf and flooding rain are plausible for the western islands. Hurricane watches could be issued as early as Saturday night or Sunday morning if the projected track holds.

But the central disagreement is embedded in the forecast itself. Models broadly agree that Lowell will make the unusual northward turn; they remain far less certain about when. An approaching North Pacific system is expected to absorb the remnants of Hurricane Karina, forming a larger trough that could pull Lowell off its westward course. Small timing changes in that interaction could separate a close offshore pass from landfall.

Forecasters are trying to close that gap before the decisive weekend window. NOAA scheduled at least four reconnaissance flights into Lowell on Friday and Saturday, including low-level drone missions, while also sampling Karina and the approaching trough. Google DeepMind’s WeatherNext model has leaned toward a close Kauai pass, underscoring the risk — but not eliminating the uncertainty. For Hawaii, the next 48 hours will determine whether a rare atmospheric turn becomes a direct emergency.
