Hurricane Simon Strengthens, Threatens Flooding in Mexico's Puerto Vallarta

Hurricane Simon intensified to 155 mph winds and moved near Mexico’s Pacific coast, posing a threat of life-threatening flooding and mudslides to parts of southwestern Mexico. The hurricane’s center was expected to impact the Puerto Vallarta area around midnight Sunday and continue through Monday morning. Jalisco state suspended classes and began evacuations in 22 coastal municipalities. The hurricane is currently about 60 miles (100 kilometers) west-southwest of Manzanilla and moving north-northwest at 6 mph (9 kph). Authorities warn that the storm could bring 10 to 20 inches (25-50 cm) of rain, with some areas receiving up to 30 inches (76 centimeters), triggering dangerous flooding and mudslides, especially in steep terrain. A dangerous storm surge is also expected along the immediate coast. In Puerto Vallarta, businesses were boarding up windows as residents prepared for the storm. Tourist Ed Currie and his wife planned to stay at their hotel, while local shop owner Jesús Gómez said he would close and take shelter when instructed by Civil Protection officials. The extent to which the hurricane will directly impact Puerto Vallarta remains uncertain, as the storm’s path could shift.
