Kauai faces significant risks of flash flooding, strong winds, and extreme surf and storm surge, particularly on Monday. The uncertainty surrounding Hurricane Lowell’s trajectory means that other parts of Hawaii could also be affected if the storm veers northward. Hurricane Karina, passing northeast of the islands, and Hurricane Marie in the East Pacific, add to the potential for compounded impacts. Residents are advised to prepare for heavy winds starting Sunday, with conditions potentially worsening into Monday.
