(CNN) -- Rain began falling on the Big Island Thursday afternoon and the winds began to pick up as Hurricane Iselle zeroed in on Hawaii. The outer bands of the storm reached the eastern part of the island, bringing wind gusts as fast as 65 mph. By Thursday, the shelves of many supermarkets were swept bare. Schools and government offices closed. Sandbags were being filled and placed around homes and hotels. Ports were told to close. In Hawaii County, where there is a hurricane warning, 630 people have gone to shelters, Mayor Billy Kenoi told CNN affiliate KHON. Gwendolyn Hill, who operates a bicycle tour on the island, said she normally goes to the store at 5:30 a.m. and is usually the only one there.
