A powerful eastward-moving mid-level trough across the central United States turned the hurricane northeastward and caused it to gradually speed up. Vertical wind shear increased as strong upper-level southwesterly flow increased, though in spite of the shear Wilma continued to intensify. Early on October 24, Wilma re-gained major hurricane status while about 120 miles (195 km) west-southwest of Key West, Florida. It slowly became better organized, with the large 50 mile (80 km) eye becoming very distinct on satellite and radar imagery. Wilma was able to retain its strength because large eyes in tropical cyclones are more stable and more resistant to vertical wind shear. Despite wind shear values of about 30 mph (48 km/h), Wilma strengthened further to reach winds of 125 mph (200 km/h). It weakened a little bit as it approached Florida, and made landfall at Cape Romano with winds of 120 mph (195 km/h) at around 1030 UTC on October 24.
