Hurricane Lowell Threatens Western Hawaiian Islands as It Turns North
9/6/2026, 11:06:46 AM
Core Event: Approaching Hurricane Lowell
- Who – Hurricane Lowell, a Pacific cyclone that reached Category 5 with 160 mph winds before settling at Category 4.
- What – Forecast to turn north, passing west of Kauai and Niihau with heavy rain, storm surge, flash-flooding risk, and life-threatening surf.
- When – Latest advisories (early September) place the center several hundred miles south-southwest of the islands, with closest approach late Monday night into Tuesday.
- Where – Impacts focused on the western Hawaiian Islands, especially Kauai County and the Papahanaumokuakea Marine National Monument.
- How – An upper-level low is expected to erode the ridge steering Lowell, causing the pivot northward and acceleration.
Background & Context
Three simultaneous hurricanes (Lowell, Karina, Marie) are active in the central and eastern Pacific—the first such clustering in more than a decade. A strong El Niño is warming Pacific waters, fueling rapid intensification. Lowell’s projected track mirrors that of the 1992 Hurricane Iniki, reminding residents of Hawaii’s limited hurricane history.
Data & Statistics
- Intensity – Maximum sustained winds of 145 mph (Category 4) as of early September; brief Category 5 peak at 160 mph on September 4.
- Wind field – Hurricane-force winds extend ~60 mi from the center; tropical-storm-force winds reach ~160 mi.
- Rainfall – Forecast totals of 3-6 in across the islands, with isolated amounts exceeding 10 in on Kauai and the Big Island.
- Storm surge – Potential water levels 1-3 ft above ground in Kauai County and up to 1 ft in Oahu if surge coincides with high tide.
- Surf – Waves of 12-14 ft expected on south and east shores; life-threatening surf and rip currents likely for several days.
Official Statements & Responses
- The National Hurricane Center warns Lowell will remain near major-hurricane strength at its closest approach and that watches may be required for Kauai County and the marine monument.
- The National Weather Service in Honolulu emphasizes flash-flooding and mudslide hazards in steep terrain and urges residents to know evacuation zones and avoid flooded roads.
- Gov. Josh Green declared a state of emergency, activating the Hawaii National Guard and pre-positioning high-water vehicles for Kauai.
- Mayor Rick Blangiardi cautioned that “this is not a time for alarm, but it is absolutely a time to pay attention.”
On-the-Ground Reports
- Kauai residents are stocking emergency kits, securing outdoor items, and monitoring alerts.
- Former lifeguard Ken Suiso described the swell’s rapid change, noting waves can jump from 2 ft to 15 ft within hours.
Conflicting Reports & Gaps
- Track uncertainty – The NHC notes a “considerable spread” among models: some place Lowell’s center 100-200 nm west of Kauai, while a minority suggest an eastward jog that could bring the core within 50 nm.
- Intensity outlook – Forecasts vary from maintaining Category 4 strength to weakening to Category 2-3 before closest approach.
Why It Matters
Even a glancing blow could trigger flash floods, mudslides, and power outages on steep terrain, threatening infrastructure and tourism during the holiday weekend.
What’s Next
- A Tropical Storm Watch is expected for Kauai County by Saturday, with possible escalation to a Hurricane Watch.
- Hurricane Hunter aircraft are scheduled to fly into Lowell later this week to refine intensity estimates.
- Residents should complete hurricane kits, secure property, and stay tuned to official alerts through the next several days.
