Shortly afterwards, increased wind shear took its toll on the system, causing Genevieve to lose its organization as it continued westward, under the influence of a subtropical ridge and the Intertropical Convergence Zone. After the low-level circulation center was exposed and became separated from the deep convection, the NHC downgraded Genevieve to a tropical depression on July 26. Although deep convection increased near the center early on the next day, Genevieve continued to fight westerly shear when crossing 140°W, moving into the waters monitored by the Central Pacific Hurricane Center (CPHC). Due to the lack of deep convection, the CPHC indicated that Genevieve had become a post-tropical remnant low early on July 28, as only a low-level cloud swirl remained. However, the CPHC noted the possibility of re-development since shear was forecast to decrease.
