Hurricane Simon is just off the Pacific coast of Mexico and is expected to move inland as an extremely powerful storm. Simon has strengthened to 155 mph, just below the threshold for a Category 5 storm. It is about 60 miles west-southwest of Manzanilla. The hurricane could bring 10 to 20 inches of rain over parts of southwestern Mexico, with some areas receiving up to 30 inches. The center warns of life-threatening flooding and mudslides. Jalisco state has suspended classes and begun evacuations. Businesses in Puerto Vallarta are preparing for the storm, with many boarding up windows and taking precautions.
