Flash flooding risk remains due to Lowell; Hurricane and Tropical Storm Warnings cancelled
(Update: 8 a.m. Tuesday, Sept. 8, 2026) A risk of flash flooding risk remains in the Hawaiian Islands due to Hurricane Lowell. Hurricane and Tropical Storm Warnings have since been cancelled for Hawaiʻi.
At 8 a.m., the center of Hurricane Lowell was located about 190 miles NNW of Līhuʻe, Kauaʻi, and 285 miles NW of Honolulu, Oʻahu. Lowell is moving toward the north near 18 mph. This general motion is forecast through today, taking the core of Lowell farther from Kauaʻi County. Lowell is then forecast to turn toward the northwest and west and slow down on Wednesday and Thursday after passing the main Hawaiian Islands.
Maximum sustained winds have decreased to near 80 mph with higher gusts. Further weakening is forecast, and Lowell should become a tropical storm later today and continue to weaken for the next couple of days. Hurricane-force winds extend outward up to 70 miles from the center and tropical-storm-force winds extend outward up to 230 miles.
RAINFALL: Hurricane Lowell is expected to produce additional rainfall totals of 2 to 4 inches for Kauaʻi, with maximum storm totals of 24 inches possible. For the Big Island, an additional 3 to 6 inches of rain is expected with isolated storm totals of 8 inches possible. For Oʻahu and Maui counties, an additional 1 to 3 inches of rain is expected with isolated storm totals of 8 inches possible. This rainfall may produce significant flash flooding and mudslides, especially across Kauaʻi county and portions of the Big Island.
STORM SURGE: Water levels may remain elevated along the coasts of Niʻihau, Kauaʻi, and Oʻahu due to large waves, and will begin to subside after the next high tide cycle.
SURF: Swells from Lowell will continue to generate life-threatening surf and rip current conditions during the next few days across many of the Hawaiian Islands. Please consult products from your local weather office.
