Several tornadoes hit southern Louisiana and Mississippi on Tuesday, killing at least three people, injuring more than 30, and destroying dozens of homes and businesses, weather and emergency officials said. Hardest hit in Louisiana was the Mississippi River town of Convent, where 90 percent of the estimated 160 mobile homes were demolished, state police said. Louisiana Governor John Bel Edwards said two people died at the mobile-home park and two or three others were missing. Authorities said they hoped the missing would be found at hospitals or elsewhere among the survivors in Convent, about 100 kilometers west of New Orleans.
