In Quintana Roo, 5,000 people from Chetumal and surrounding low-lying areas were forced to evacuate to 30 shelters. Offshore along a coral reef, about 50 fishermen stayed on a coral reef during the storm. In the Bay of Campeche, Pemex evacuated about 6,300 workers from its offshore oil platforms. Officials in Yucatán and Veracruz declared states of emergency. When Keith reached the Gulf of Mexico and began re-intensifying, a hurricane warning was issued from Tuxpan to Matamoros in northeastern Mexico, with a tropical storm watch issued northward to Port Mansfield, Texas. About 3,000 residents in Tamaulipas evacuated to 250 shelters, and in neighboring Veracruz, about 175 people left their houses before the storm struck. The threat of Hurricane Keith caused Mexican authorities to close most ports along the gulf coast, and many schools in the area were closed.
