During the morning of August 8, Genevieve started to track northward along the western edge of a subtropical ridge to the east and northeast.That noon, more fragmented deep convective banding revealed that Genevieve had begun a weakening trend. As the result, the JTWC downgraded Genevieve to a typhoon late on the same day, as convection surrounding the system warmed. Early on August 9, Genevieve accelerated north-northeastward, and it began to encounter increasing vertical wind shear of 35 mph (55 km/h) with subsidence along the western side and weakening outflow into the TUTT cell. The eye of the typhoon became cloud-filled, while the deepest convection around the core was also became warmer. The system began to track north-northwestward in the afternoon, when the cold dense overcast has decreased in size and become less symmetric.
