Kauai Officials Urge Vigilance, Prepare for Heavy Rain and Flooding

On December 12, 2025, County of Kaua‘i officials issued an advisory asking the public to be vigilant as the National Weather Service forecast potential heavy rain and a slight chance of thunderstorms that could lead to flash flood conditions. Forecasters said lingering moisture would likely keep the pattern showery, with rain approaching from the usual leeward areas and persisting into early next week. County, state, and federal agencies said they will continue to monitor conditions and coordinate preparations.

The advisory emphasized practical steps residents should take to reduce risk and protect emergency response capacity. Officials reminded the public to use 911 only for life threatening or time critical emergencies, noting that non emergency calls for weather updates or road conditions can delay urgent response. For road status and closures call 8082411725. To report non emergency road hazards contact Kaua‘i Police Department dispatch at 8082411711. For recorded weather information call the National Weather Service automated line at 8082456001 or visit weather.gov/hfo.

Officials warned that Kūhiō Highway near the Hanalei Bridge may be closed with little or no advance notice if a Flash Flood Warning is issued, and that utilities and other services could be disrupted. Customers are advised to update contact information with Kaua‘i Island Utility Cooperative at 8082464300 to receive outage alerts. Standard preparedness recommendations included using surge protectors and unplugging unnecessary appliances, keeping battery powered radios and flashlights with fresh batteries available, and staying away from downed power lines while reporting them to 911.

Outdoor recreation will be affected as river and stream crossings, trails, and coastal areas can become hazardous quickly. Residents and visitors are advised to check conditions before hiking, river travel, or beach excursions, and not to cross swollen rivers or streams. County lifeguards should be consulted before entering the ocean during unsettled weather. To receive official emergency notifications sign up for the county Wireless Emergency Notification System via kauai.gov/KEMA or call the Kaua‘i Emergency Management Agency at 8082411800.

The advisory focuses on preserving life and mobility, while urging community members to update contact details and follow official channels so emergency services can respond effectively if conditions deteriorate.
