Hurricane Lowell Strengthens to 140 MPH, Brings Life-Threatening Swells to Hawaii

Satellite sensors track the tightly coiled cloud structure of a major tropical cyclone churning across the warm waters of the Pacific basin. Even when upper-level wind shear begins to disrupt the storm's eyewall structure hundreds of miles offshore, powerful ocean swells propagate outward to produce hazardous coastal surf and outer rain squalls long before the storm's circulation center approaches land.

During early September 2026, the Pacific tropical cyclone season showed active conditions with multiple storm systems in the Eastern and Central Pacific basins. On September 3, NOAA reported Major Hurricane Lowell approximately 450 miles south-southwest of Hilo with 140-mph sustained winds.

The Central Pacific Hurricane Center and the National Hurricane Center tracked Lowell’s position and movement. Swells generated by the storm were expected to affect the Hawaiian Islands over the weekend, creating dangerous surf and rip current conditions.

NOAA advised interests in the Hawaiian Islands to monitor Lowell’s progress. Coastal forecast products emphasized the threat from swell, not only the storm center itself, because wave energy can reach shore before the core arrives.
