A flood warning has ended for Kauai and Oahu after heavy rain and flooding conditions eased, but officials continue to monitor roadways, rivers and other areas affected by the storm. Kuhio Highway remains closed at the Hanalei Bridge on Kauai, where rising water created ongoing travel concerns.
The severe weather alerts were canceled after a period of intense rainfall across both islands. The National Weather Service had issued a flash flood warning for much of Kauai, while Oahu was placed under a flood advisory because of heavy rain over the Koolau mountains.
Flood Warning Ends as Rainfall Eases Across the Islands
On Kauai, the flash flood warning remained in effect through much of the afternoon and evening before being canceled at 11:45 p.m. The alert covered areas vulnerable to rapid runoff, including locations near streams, rivers and low-lying roads.
Oahu’s flood advisory lasted until 10 p.m. Rainfall over the Koolau mountains reached rates of approximately 1 to 3 inches per hour, creating the potential for ponding on roadways, overflowing drainage channels and dangerous driving conditions.
Although the alerts have expired, residents and visitors are being urged to remain cautious. Floodwater can continue moving through waterways even after rainfall decreases, and roads may remain blocked or hazardous because of debris, erosion or rising water.
Critical Road Closure Remains at Hanalei Bridge
Kuhio Highway is still closed at the Hanalei Bridge, one of Kauai’s key routes. The closure is expected to affect people traveling between communities on the island’s north shore.
Water was also rising rapidly along the south fork of the Wailua River, according to the report. Residents near rivers and streams should avoid crossing flooded areas and should never drive around barricades or through moving water.
Road conditions can change quickly during and after heavy rain. Even a shallow layer of fast-moving water can sweep away a vehicle, hide damaged pavement or make a roadway impossible to navigate safely.
What Kauai Residents Should Know Now
Kauai residents seeking road and emergency information can contact the Kauai Emergency Management Agency or use the county’s notification services. Officials also encourage residents to follow verified public safety updates before traveling.
- For road conditions and closures, call 808-241-1725.
- For weather updates, call the National Weather Service automated line at 808-245-6001.
- For emergency management assistance, call 808-241-1800.

Residents can also sign up for Kauai’s emergency notification service through the county. Text alerts are available by sending KAUAIEMA to 888777.
Lingering Flood Risks Remain After Alerts Expire
The end of a flood warning does not mean every danger has disappeared. Saturated ground can contribute to additional runoff, while swollen rivers may remain elevated for hours after the heaviest rain ends.
People living near streams, valleys and steep slopes should keep an eye on changing conditions. Drivers should allow extra time, avoid closed roads and turn around if they encounter water covering the pavement.
On Oahu, the expired advisory signals that the most intense rainfall has passed, but isolated showers and localized flooding may still occur. Residents in areas that received the heaviest rain should continue watching for updates from local officials and weather authorities.
Hawaii News Now reported that severe weather alerts were canceled after conditions improved. However, the continuing Hanalei Bridge closure and rising water along the Wailua River show why caution remains important across Kauai.
