Honolulu -- The National Weather Service placed Kauai and Oahu under a flash flood warning Wednesday morning as an anticipated storm system arrived.

The storm is also forecast to bring strong southwest winds. A wind advisory for much of the state begins at noon Wednesday.

Kauai and Oahu could see the worst of the storm on Wednesday, forecasters said.

Forecasters said conditions could bring heavy showers or thunderstorms and stall over the central islands on Thursday.

Forecasters say the heaviest rainfall amounts will most likely affect the western half of the state, but that there could be a threat of flash flooding on all islands. There is also a chance of thunderstorms that may cause rainfall totals to increase even more.
