Officials warn of potentially inclement weather into the weekend

Published on April 07, 2026

LĪHU‘E – County of Kaua‘i officials are urging the public to be vigilant due to potential severe weather conditions beginning Wednesday into the weekend.

The National Weather Service forecasts a notable shift in the weather pattern for Kauaʻi as a developing low-pressure system northwest of the state pulls deep tropical moisture northward, bringing strengthening southerly winds, widespread showers, and the potential for thunderstorms from midweek through the weekend. Periods of heavy rain are possible, particularly as a moisture band lingers near the island, and conditions are expected to become more organized and impactful Wednesday through Friday, when a Flood Watch is in effect. Gusty southerly winds may increase later in the week, especially near heavier showers and along exposed and windward areas. With soils still saturated from recent heavy rains, any bursts of intense rainfall could quickly lead to runoff, rising streams, and localized flooding, so residents are urged to stay weather aware as this unsettled pattern takes hold.

County services and facilities may close on little to no notice, depending on the severity of the incoming storm and its effects.

County, state, and federal officials will continue to monitor the situation and actively coordinate in preparation for this potential event.

Officials remind the public to use 9-1-1 only for life-threatening or time-critical emergencies. Calls to 9-1-1 for weather updates or general road conditions can significantly delay emergency response. For road status and closures, call 808-241-1725. To report non-emergency road hazards, contact KPD Dispatch (non-emergency) at 808-241-1711. For weather information, call the National Weather Service automated line at 808-245-6001 or visit www.weather.gov/hfo.

Officials note that Kūhiō Highway near the Hanalei Bridge may be closed with little or no advance notice, particularly if a Flash Flood Warning is issued. Utilities and other services may also be disrupted.

Standard tips to prepare for power outages from KIUC include:

• Use surge protectors to protect your appliances & equipment
• Turn off & unplug all unnecessary appliances or equipment
• Keep a portable battery-powered radio & flashlights with extra batteries
• Stay away from downed lines & report to 9-1-1
• Contact KIUC at 808-246-4300 to update your contact information & receive alerts

The public is advised to check conditions before venturing out for hiking, river, or beach excursions. River and stream crossings, recreational trails, and other outdoor recreation areas may quickly become hazardous. During severe weather, emergency rescues may not be possible. Do not cross swollen rivers or streams; always check with a lifeguard at any lifeguard station before entering the ocean. Know before you go. For up-to-date information about Kaua‘i ocean conditions and safety, please speak to a county lifeguard, visit www.safebeachday.com, or call the Ocean Safety Bureau at 808-241-4984.

Officials also advise the public to be aware of potentially heavy ponding across various portions of the island. The Public Works Roads Division is actively working on clearing drains and other proactive storm mitigation measures. Kūhiō Highway in the vicinity of the Hanalei Bridge remains open. Officials will continue to monitor stream gauges.

The Department of Health Clean Water Branch has issued Brown Water Advisories from Lydgate Beach to Wailua Beach and from Nāwiliwili to Kalapaki Beach.
