One of the victims was a 71-year-old woman who drowned in Colima state after a strong current swept away the car in which she and her son were riding.
Jova passed only about 12 miles from Puerto Vallarta, where officials had piled sandbags and tarps across a beach volleyball court that will be used in the Pan American Games, which start on Friday.
Officials of the games, centered around Guadalajara, assured arriving guests and athletes that the storm would not interfere with the competition.
