On the state's most populated island, which is about 200 miles (320 kilometers) north of the Big Island, employees of the Sheraton Waikiki resort filled sandbags to protect the Oahu oceanfront hotel from surging surf. Stores along Waikiki's glitzy Kalakaua Avenue stacked sandbags along the bottom of their glass windows to prepare for heavy rain and flash flooding.

Hurricane Lane, which was still offshore, already lashed the Big Island with nearly 20 inches (50 centimeters) of rain in nearly 24 hours and was moving closer, putting it and Maui "in the thick" of the storm, National Weather Service meteorologist Melissa Dye said. The agency says the storm has weakened to a Category 3 but can still cause major damage.
