Hurricane Lowell expected to turn northward, bringing strong winds and heavy rain to Hawaiian islands

Hurricane Lowell, a Category 4 storm with sustained winds of about 150 mph, is moving west at roughly 7 mph and is expected to slow, turn sharply northward or north-northeastward on Sunday, Sept. 6, before accelerating, the National Hurricane Center said. The center of the storm is projected to pass 100 to 200 nautical miles west of Kauai on Sept. 7, with the right-front quadrant likely to affect the island.

"Any deviation eastward from its forecast track could bring more severe wind impacts, especially to Kauai County," the National Weather Service in Honolulu warned. The agency said it will consider issuing watches and warnings later on Sept. 5.

Lowell's hurricane-force winds extend up to 60 miles from its center, while tropical-storm force winds reach out about 160 miles. Heavy rainfall is expected across the islands, with totals of 3 to 6 inches possible and localized amounts exceeding 10 inches on Kauai and the Big Island. The National Weather Service cautioned that such rain could trigger flash flooding and mudslides, particularly on steep terrain.

Swells generated by Lowell and the remnants of Hurricane Karina are forecast to produce life-threatening surf and rip currents on south- and east-facing shores, with high-surf advisories already in effect. The combined effect of large swells and monthly high tides may threaten harbor entrances, coastal properties and roads.

Officials urged residents to review hurricane safety plans, know evacuation zones, avoid driving on flooded roads and assemble emergency kits with at least three days of water, food, medications and other essentials. Multiple channels for receiving alerts, such as weather radios and emergency alert systems, were recommended.
