A surface trough moving from the southeast and south, and an upper low far west of the islands created instability statewide. These features produced heavy showers and thunderstorms over portions of the state. Rainfall was particularly intense over Kauai, and this led to flash flooding over northern parts of the Garden Isle. There were no reports of serious injuries. The costs of any damages were not available.
