VILLAHERMOSA, Mexico (AP) - Thousands of people huddled on their rooftops Wednesday to escape flooding in the Gulf coast state of Tabasco as a tropical depression dumped torrential rains on central and southern Mexico. At least 83 people have died because of flooding in 10 states. A state spokesman, Jaime Molina, reported 42 dead in Puebla state, most by mudslides, with 150 others missing. He said at least 25 died around Teziutlan, a mountain city 110 miles east of Mexico City. In coastal Veracruz state, officials late Wednesday reported 16 more deaths, bringing that state's total to 35. Torrential rains from the season's 11th tropical depression have caused southeastern Mexico's worst flooding in 40 years and have forced more than 157,000 people from their homes over the past week.
