We still haven't reached the peak of what's expected to be an above-average hurricane season. Two other storms - Emily and Gert - are moving through the open Atlantic and don't appear poised to make landfall. Tropical storm Franklin, currently in the Caribbean Sea, is expected to bring strong winds and heavy rainfall to Puerto Rico throughout the middle of the week. It's not just Hilary: Three tropical storms are churning over the Atlantic Ocean at the moment, with a fourth looking possible in the Gulf of Mexico amid a spate of thunderstorms. "The ocean temperatures off the coast of Baja California are much warmer than usual right now," Swain says, "As much as 3 to 6 Fahrenheit - that’s a pretty significant increment of additional hurricane fuel." Temperature anomalies there are part of what’s been fueling this storm, says UCLA climate scientist Daniel Swain. Part of the ocean that Hurricane Hilary formed over is around Baja California, Mexico, in the Pacific. Forty percent of the world’s oceans are experiencing heat waves right now, according to federal researchers, in part due to a natural climate pattern called El Nino and human-caused climate change. The ocean is a lot warmer than usual this summer. That's because hot ocean water is a sort of fuel, an energy source for hurricanes. Hurricanes are more likely to be larger and more powerful when they form over hotter ocean water. But humans' use of fossil fuels means that the whole Earth is heating up, and the ocean stores a lot of that heat. Scientists will need time to determine the role climate change played in Hurricane Hilary's formation and behavior.
