Oceans are supercharging hurricanes past Category 5

Deep ocean hot spots packed with heat are making the strongest hurricanes and typhoons more likely-and more dangerous. These regions, especially near the Philippines and the Caribbean, are expanding as climate change warms ocean waters far below the surface. As a result, storms powerful enough to exceed Category 5 are appearing more often, with over half occurring in just the past decade. Researchers say recognizing a new Category 6 could improve public awareness and disaster planning.
