A tornado that tore through the Hattiesburg area overnight killed three people, closed parts of Interstate 59 and left nearly 15,000 homes and businesses without power. And as emergency crews are responding to disaster needs, officials are also preparing for another round of severe weather this evening. All three fatalities were in Hattiesburg. Forrest County Coroner Butch Benedict said two of the fatalities were in a trailer park off Edwards Street. The third was from a residence off Crestwood Drive.
