The combination of a nearby surface low and upper trough brought heavy showers and thunderstorms to parts of the Aloha State, mainly Kauai, Oahu, and Maui.  Some of the rainfall was enough to cause flash flooding in a few instances.  However, there were no reports of serious injuries.  The total cost of damages was not known, but a report about flooding at Waimea Valley Park on Oahu on the 28th indicated damages in the $10's of thousands.
