Floods have ravaged the states of Puebla, Tabasco and Veracruz, and travel to these regions should be deferred. Secondary roads are unsafe here and also in the states of Chiapas, Hidalgo, Jalisco, Michoacan and Oaxaca. In Villahermosa, the capital of Tabasco state, angry residents clashed with police Oct. 11 over complaints that the government was promising help but doing little. Much of the city has been under water for a week.
