Hurricane Nolo is heading toward the Hawaiian Islands, bringing with it the potential for "catastrophic flash floods and potentially deadly" flooding, according to the U.S. National Weather Service. Initially a tropical storm, Nolo was upgraded to a hurricane on Thursday and is now moving north-northwest across the Pacific Ocean. Heavy rainfall is expected to reach the eastern part of the Hawaiian archipelago by Saturday, September 26, with the National Hurricane Center (NHC) warning that the main island of Hawaii could face severe flooding over the weekend. In addition to flooding, there is a risk of landslides due to the heavy rain. The NHC has issued a flood warning that remains in effect until 6 p.m. local time on Saturday, which corresponds to 6 a.m. on Sunday in mainland France. Hurricane Nolo is currently generating sustained winds of nearly 130 kilometers per hour, with even stronger gusts in certain areas, as measured by air force reconnaissance aircraft. The storm is expected to continue strengthening and could become a "major hurricane" by Saturday, according to the NHC. Hawaii is still recovering from the effects of Hurricane Lala, which struck the southern part of the main island in August, bringing damaging winds and severe flooding. This is the second major storm to impact the islands in recent months, following Hurricane Lowell, which swept through the western islands in early September. These repeated storms have placed additional strain on local communities and emergency services, which are now preparing for the potential impacts of Hurricane Nolo.
