A powerful Hurricane Iselle will weaken before reaching Hawaii later this week but heavy rain, strong winds and rough seas will affect the islands. Although currently a powerful Category 4 hurricane, the National Hurricane Center expects Iselle to weaken considerably over the next several days and be a tropical storm when it finally reaches the islands.
The Big Island of Hawaii will be the first to feel the impacts from Iselle as it is forecast to reach the island by Thursday evening, Hawaiian time. At present track, the center of circulation will pass just north of the Big Island of Hawaii and then near some of the smaller islands, such as Maui or Oahu. It is even possible that it could make landfall on one of the islands before the end of the week.
Due to the projected track of the storm, areas on the northern and eastern portions of the islands will likely feel greater effects than the southern and western sides. However, if the projected path of the storm shifts, Iselle could make a direct hit on the Big Island. A direct hit on the islands does not have to occur for significant impact as the storm is much larger than a single point of latitude and longitude.
