Convection continued but the cyclone was encountering extensive easterly to north-easterly wind shear which stinted the strengthening of this storm throughout its history. The cyclone initially headed toward the west-northwest around a subtropical ridge that was centered over the western Gulf of Mexico. The depression moved north west, parallel with the west coast of Mexico due to being steered by the mid/upper-level ridge. On August 31, it strengthened to become Tropical Storm Henriette, 85 miles (137 km) south of Acapulco.
