No, tropical disturbances do not need high pressure in the center of their eye to become a full hurricane. In fact, tropical disturbances are the initial stage of a tropical cyclone, which is a low-pressure weather system formed over warm tropical oceans. These disturbances begin to organize and intensify when atmospheric conditions are favorable, such as warm sea surface temperatures, low vertical wind shear, and abundant moisture. As they develop, they can evolve into tropical depressions, then tropical storms, and finally full-fledged hurricanes. The development and intensification of tropical cyclones depend on various factors, and while a well-defined eye with high pressure in the center is characteristic of mature hurricanes, it is not a requirement for their formation or progression.
