Weather officials say Tropical Storm Flossie is weakening as it moves westward across the Pacific toward Hawaii. But the storm is still expected to bring heavy rain and winds up to 60 mph, along with the possibility of flash flooding and mudslides.
The National Weather Service said midday Sunday that Flossie is expected to reach the eastern end of Hawaii late Sunday night.
Weather officials issued a tropical storm warning for Oahu, Hawaii's most populous island, to go along with previous warnings for the Big Island, Maui, Molokai and Lanai.
The service also issued a tropical storm watch for Kauai and Niihau.
Officials warned people to cancel beach trips, finish necessary storm preparations and evacuate if asked by local officials.
It's not immediately clear which island faces the most danger.
