Tropical Storm Alberto, the season's first named storm, weakened on Thursday as it moved inland over northeast Mexico after bringing heavy rains to parts of the parched region and leaving at least four people dead. Heavy rain amounting to several inches fell inland in Mexico's Tamaulipas, Nuevo Leon and Coahuila states. Alberto had spurred tropical storm warnings covering most of the western Gulf of Mexico's coastline from Texas to Veracruz. The storm made landfall with maximum sustained winds of 75 km per hour.
