Update may 2, 3:30 p.m.: The National Weather Service has canceled the flood advisory for Kauaʻi, but a flood watch remains in effect until 6 a.m. Wednesday. High surf advisory remains in effect.

Update May 2, 12:30 p.m.: The National Weather Service has issued a flood advisory until 3:15 p.m. on Tuesday on Kauaʻi. At 12:13 p.m., radar and automated rain gauges indicated heavy rain over the northeast portion of Kauaʻi. The heaviest rain was falling between Wailua and Anahola at a rate of 1 to 3 inches per hour.

Update May 2, 7 a.m.: In addition to the flood watch, the National Weather Service also has issued a high surf advisory for Kauaʻi and Niʻihau for north- and west-facing shores.

The forecast is for surf of 12 to 16 feet along north-facing shores, and 8 to 12 feet along west-facing shores. Strong breaking waves and strong currents will make swimming dangerous.


Update May 2, 6 a.m.: The National Weather Service now has Kauaʻi and Niʻihau under a flood watch until early Wednesday morning.

Unstable conditions with slow-moving heavy showers and thunderstorms will develop through early Wednesday morning as a low-pressure system approaches the islands from the northwest.

Flash flooding caused by excessive rainfall is possible.
