Aug 11 (Reuters) - Wildfires on Hawaii's Maui island and Big Island have killed at least 55 people, forced thousands of residents and tourists to evacuate, and devastated the historic resort city of Lahaina. WHAT'S DRIVING THE HAWAII WILDFIRES? Winds from Hurricane Dora, hundreds of miles southwest of the Hawaiian Islands in the Pacific Ocean, have fanned the flames across the U.S. state, officials say. There was no estimate for the Upcountry fire in the mountainous center of the eastern mass of the island, Maui County said. The island of Maui lies to the north and west of the island of Hawaii.
