Kona Storms Flood Oʻahu

Back-to-back low-pressure systems struck Hawaii in March 2026, delivering some of the worst flooding the state has seen in decades. The subtropical weather systems—called kona lows near Hawaii—siphoned moisture from the tropics, fueling slow-moving thunderstorms with torrential, destructive rains.

While the most intense rains had subsided by March 24, forecasters are continuing to monitor unsettled weather and the possibility of more flash floods in the coming days.
