“Hurricane Ivan passed by the extreme western tip of Cuba on 13 September as a Category 5 hurricane but again weakened to Category 4 strength once it entered the Gulf of Mexico. Wind shear and cooler waters caused Hurricane Ivan to further weaken before making its first U.S. landfall. On the morning of 16 September, the hurricane made landfall near Gulf Shores, AL, on the Alabama-Florida border, as a Category 3 hurricane with winds of 193 km/h (120 mph) and a 4.3-m (14-ft) storm surge. It weakened rapidly over land, becoming a tropical depression later that day.”
