- Lowell has dropped to a Category 3 storm with sustained winds near 120 mph as it tracks just west of Kauai and Niihau overnight, after twice reaching Category 5 strength earlier this month — only the third Pacific hurricane on record confirmed to hit that intensity twice.
- A Tropical Storm Warning covers both islands, with forecasters calling for up to 14 inches of rain in higher terrain, surf as tall as 20 feet on south- and west-facing shores, and gusts that could top 75 mph.
- Gov. Josh Green declared a state of emergency and mobilized 129 National Guard members; Kauai has opened five shelters as officials privately measure Lowell against 1992's Hurricane Iniki, the last storm to hit the island head-on.
Hurricane Lowell is sliding past Kauai and Niihau overnight several hundred miles weaker than the monster it was a week ago, though forecasters warn the storm still carries enough punch to trigger flash floods, mudslides and dangerous surf across Hawaii's western islands before it clears out Tuesday night.
