MEXICO CITY—Southwestern Mexico braced for heavy rain and mudslides Wednesday after Polo, a powerful Pacific cyclone, became a major hurricane. Forecasters also warned another system headed for Hawaii could cause catastrophic flooding later in the week.
Hurricane Polo, an “extremely dangerous” storm, is expected to skirt Mexico’s Guerrero state, submerging coastal areas with 4 to 6 inches (10 to 15 centimeters) of rain through Thursday, according to the National Hurricane Center in Miami.
