Genevieve reformed a eye with more symmetric and organized convection for short time early on August 10, but the eye disappeared very soon as the system elongated further. Upper-level analysis indicated a complex environment— an anticyclone located to the southeast, a TUTT cell to the west, and a second anticyclone to the north. The TUTT cell and the first anticyclone caused strong upper-level southwestern flow and moderate vertical wind shear over the system, but the issues were offset by the quick speed of the typhoon. Tracking northwestward, Genevieve crossed 30°N at noon and began to encounter cold sea surface temperatures less than 79 °F (26 °C) which do not support tropical cyclones. At the same time, a trough expanded the region of subsidence, isolating the core from the tropical moisture along the equatorward periphery. Later, deep convection along the tightly-wrapped low-level circulation center of the typhoon diminished fast as dry air surrounded the system.
