Shortly after Keith reached peak intensity, the eye had moved over portions of Belize, causing it to lose definition. Outflow became restricted, and the developing disturbance to the northeast increased wind shear. As a result, Keith began to weaken steadily on October 1. While remaining nearly stationary, Keith made a landfall on Ambergris Cay late on October 2 as a minimal hurricane. Shortly thereafter, Keith weakened into a tropical storm, and its convection became limited to the southeastern quadrant. At 0300 UTC, the storm made its second landfall about north of Belize City, and within nine hours weakened into a tropical depression. The building ridge to the north caused the system to accelerate more to the west-northwest across the Yucatán peninsula. Early on October 4, Keith emerged into the Bay of Campeche, where favorable conditions allowed convection to quickly redevelop. Later that day, it re-intensified into a tropical storm, with improved outflow and convective organization. On October 5, the Hurricane Hunters reported a circular eye had reformed along with winds supporting an upgrade to hurricane status. Keith intensified further that day, until it made its final landfall north of Tampico with winds of 90 mph (150 km/h). It rapidly weakened over the high terrain of northeastern Mexico, dissipating late on October 6.
