HONOLULU (HawaiiNewsNow) – Heavy rainfall, strong thunderstorms, powerful winds and hail is once again in the forecast for parts of the state.

The National Weather Service in Honolulu has issued a Flash flood watch until 4 a.m. Saturday for:

  • Maui
  • Molokai
  • Lanai
  • Oahu
  • Kauai

A surface trough in the vicinity of Maui is forecast to move west through Friday. The trough will be interacting with an upper level disturbance resulting in a good chance of heavy rains and thunderstorms.

The threat of heavy rains and thunderstorms will spread westward from Maui this afternoon to Kauai overnight. With the saturated ground any additional rainfall will bring increased runoff that could produce flash flooding...potentially resulting in landslides.

The City and County of Honolulu's Department of Emergency Management sent out this message Thursday Afternoon.

"Oahu residents can expect an increase of strong storm activity overnight and into tomorrow

The National Weather Service has informed the Department of Emergency Management that Oahu can expect an increase of strong storm activity overnight and into tomorrow.

Heavy rainfall and flooding, strong thunderstorm winds, hail and frequent periods of lightning are forecast with the peak effects occurring sometime Friday afternoon.

Although rainfall could be intense at times the bands of showers should move quickly over Oahu as the storm system tracks west of the state today thru Saturday."

Take precautions if you live in a flood prone area and stay tuned.

Sunday should see drier more stable weather.
