The National Weather Service in Honolulu issued a Hurricane Warning at 11:09 PM HST on September 6 for the island of Kauai and nearby Niihau. The warning covers eight zones: Kauai North, South, East, Southwest, the Kauai Mountains, Niihau, and the island’s northwest and leeward coastal waters.
A Hurricane Warning means hurricane conditions – sustained winds of 74 mph or higher – are expected within the warning area, typically within 36 hours. A warning of this kind is issued when there is little time left to prepare, so residents should treat this as a signal to act now, not to wait for more information.
What You May Notice
Conditions will likely deteriorate through the night and into tomorrow. Expect strengthening winds, heavy rain, rising surf along exposed coastlines, and possible power outages. Coastal and marine areas, including the northwest and leeward waters, face dangerous seas – all small craft should already be in port. Low-lying areas and the mountain zones may see flash flooding and debris flows as rain bands move in.
Sensible Steps Right Now
First, secure loose outdoor items, charge phones and battery packs, and make sure your emergency kit has water, medications, flashlights, and cash. Second, know your shelter plan: if you live in a flood-prone or coastal evacuation zone, follow instructions from Kauai County emergency management and move early rather than during the worst conditions. Third, stay indoors away from windows once winds arrive, and avoid driving – floodwater is the leading cause of hurricane-related deaths.
Continue monitoring official updates, as warnings can be expanded, upgraded, or downgraded as the storm’s track becomes clearer. This alert is based on the official warning issued by the National Weather Service (NWS) Honolulu office.
Frequently Asked Questions
What should I do right now?
Finish preparations immediately: secure loose outdoor items, charge devices, gather water, medications, and flashlights, and fuel your vehicle. If you are in a coastal or flood-prone zone, follow Kauai County evacuation guidance and move to a safe location before conditions worsen.
Which areas are under this warning?
The warning covers all of Kauai – North, South, East, Southwest, and the mountain interior – plus the island of Niihau and Kauai's northwest and leeward coastal waters.
How long will this last?
A Hurricane Warning typically covers a window of roughly 24-36 hours while the storm passes, but the NWS will keep the warning in effect until hurricane conditions are no longer expected. Monitor official updates for when the warning is downgraded or canceled.
Is it safe to go outside during the storm?
No – stay indoors and away from windows once strong winds begin. A brief calm could be the storm's eye, with dangerous winds returning shortly after, so wait for the official all-clear from local authorities.
