Mar 8, 2021 The National Weather Service has issued a flash flood warning for areas of Haiku and Pauwela downstream of the Kaupakalua Dam. Maui County warned that residents evacuating their homes due to flooding in the Haiku area should not return until it is safe. Residents have been stranded after heavy rains and flash flooding crested the Kaupakalua Reservoir and Dam and Haiku, sending fast-flowing floodwaters across roads and heavily damaging or destroying half a dozen homes, the county said. Authorities have told everyone in the vicinity of Kaupakalua Dam and makai of Kaupakalua Road to leave the area immediately, as well as people near heavily flowing streams.
