The National Weather Service has extended a flash flood warning for the island of Kauai until midnight.
A nearby disturbance triggered thunderstorms, leaving the island under a flash flood warning for much of Monday.
Flooding concerns prompted the early closure of Hanalei School, which was quickly transformed into an emergency shelter for the American Red Cross to assist any residents who chose to evacuate.
Kuhio Highway was closed near Hanalei Bridge due to flooding, and stream levels remained high for much of the afternoon and early evening, gradually lowering through the later evening hours.
Officials continue to report heavy ponding, low visibility, and other hazardous driving conditions across the island. Drivers are advised to drive with extreme caution.
On east Kauai, low water crossings on Loop Road at Wailua River were inundated.
Rain drenched other parts of the state Monday as well.
On Maui, a flash flood warning was issued for a few hours with heavy rain in west Maui, Kula, Haiku, and Hana.
Some lightning strikes were reported near Hilo and Keaau. Hawaii island was previously under a flood advisory with one to three inches of rain reported.
Oahu was under a flood advisory in the morning with moderate to heavy rainfall near the Koolau mountain range.
Meanwhile, the state will experience at least one more day of wet weather with storm remnants providing the fuel for heavy rain.
Future radar keeps moisture over the islands for another day with leeward showers during the day and windward showers at night.
Drier weather should return Wednesday.
