Tropical Storm Helene threatens the U.S., Mexico
NPRTropical Storm Helene threatens the U.S., Mexico toggle caption The National Hurricane Center Tropical storm and hurricane watches were issued for parts of the lower Florida Keys, western Cuba and Mexico’s Yucatán peninsula Tuesday morning as forecasters elevated Potential Tropical Cyclone Nine to Tropical Storm Helene. Helene formed in the northwestern Caribbean Sea, just south of the western tip of Cuba and is expected to reach hurricane strength, with wind strengths of 115 mph, by Wednesday. They expect the storm to move fast, meaning a huge inland swathe will endure the brunt of the storm and its predicted storm surge — or abnormal rise of water. Matthew Rosencrans, the lead hurricane forecaster for the National Weather Service, told NPR earlier this month that the water in the Atlantic is warmer than usual, which helps storms develop into powerful forces.
