Hurricane Bertha (1990) tropical cyclone, the depression executed an elongated counter-clockwise loop to the northeast. Conditions favored further intensification, and based on ship reports, it is estimated the depression strengthened into Tropical Storm Bertha early on July 28. Bertha quickly strengthened to attain hurricane status early on July 29 about halfway between Cape Canaveral, Florida and Bermuda.

Bertha continued slowly northeastward to ridging from the Bermuda high extending westward to the United States.
