A gradually weakening Tropical Storm Vance churned Sunday off Mexico's southwest Pacific coast but still threatened heavy rains and flash flooding in several western states of the country.
Vance, a former Category 2 hurricane as of Friday, was losing strength but still was expected to dump heavy rain on the Mexican states of Colima, Nayarit and Sinaloa, as well as parts of Michoacan, Jalisco and Durango, the U.S. National Hurricane Center in Miami said.
