Hawaii is bracing itself for a significant Kona storm, expected to bring heavy rain, strong winds, and thunderstorms across the islands. Governor Josh Green has declared an emergency to mobilize resources in anticipation of the severe weather. The National Weather Service (NWS) forecasts that the storm will initially impact Kauai, Niihau, and Oahu before spreading to other islands. The state has closed numerous parks and trails, advising residents to stay away from forested and coastal areas due to the risks of storm surge, high surf, rising streams, and falling trees. A flood watch is in effect until Saturday, with potential rainfall exceeding 20 inches in some areas, according to meteorologist Laura Farris.
