UPDATE: The flood warning is now in effect until 9:45 pm.
The National Weather Service in Honolulu has issued a flood advisory for the County of Kaua´i until 9:45 pm Tuesday night.
At 3:47 pm, radar indicated heavy rain over the island of Kaua´i. Rain was falling at a rate of 1.5 to 2.5 inches per hour.
Locations in the advisory include but are not limited to Līhu´e, Kapa´a, Kalaheo, Kekaha, Princeville, Kīlauea, North Fork Wailua Trails, Alakai Swamp Trails, Lawai, Omao, Kōke´e State Park, Wailua Homesteads, Hanalei, Hanapepe, Wainiha, Na Pali State Park, Koloa, Haena, Waimea and Wailua.
Stay away from streams, drainage ditches and low lying areas prone to flooding. Rainfall and runoff will also cause hazardous driving conditions due
to ponding, reduced visibility and poor braking action.
Do not cross fast flowing or rising water in your vehicle, or on foot. Turn around, don’t drown.
NWS has also issued a special marine warning for Kaua´i windward waters until 5 pm Tuesday.
A strong thunderstorm capable of producing waterspouts was located over Moloa´a, moving west at five knots. Waterspouts, small hail, heavy rain, lightning, and wind gusts up to 40 knots are all hazards accompanying the storm.
Waterspouts can easily overturn boats and create locally hazardous seas. Small craft could be damaged in briefly higher winds and suddenly higher waves. Locations impacted include FAD Buoy EK, Kīlauea Lighthouse and Hanalei Bay.
Boaters should seek safe harbor immediately until the storm passes.
