Later that day, the depression was upgraded to a tropical storm and was named "Bertha". Over the next three days, Bertha tracked west-northwest while gradual intensification was occurring. On July 7, Bertha was upgraded to a hurricane with sustained winds of 75 mph (120 km/h) while east of Guadeloupe.
