MIAMI Tropical Storm Hanna was upgraded to a hurricane Saturday, moving toward the Texas coast and threatening to bring heavy rain, storm surge and possible tornadoes, all while another tropical storm approaches the Caribbean. Hanna is the first hurricane of the 2020 Atlantic hurricane season, the U.S. National Hurricane Center said in its Saturday morning update. Meanwhile, Tropical Storm Gonzalo was still on track to move across the southern Windward Islands on Saturday afternoon or evening. A tropical storm warning was in effect for Tobago and Grenada and its dependencies. Gonzalo and Hanna broke the record for the earliest seventh and eighth Atlantic named storms, respectively, according to Colorado State University hurricane researcher Phil Klotzbach.
