UPDATE 11:15 p.m.
HATTIESBURG, Miss. - - The people of Hattiesburg, Miss., are trying to assess the damage after a tornado tore through the city on Sunday.
It was part of a wave of severe storms that downed trees, damaged buildings and injured more than a dozen people.
The twister traveled down one of Hattiesburg's main streets and mangled homes, commercial buildings and structures on the campus of the University of Southern Mississippi. Emergency officials say at least 10 people were injured in surrounding Forrest County and three were hurt to the west in Marion County, but they aren't aware of any deaths.
A Mississippi Emergency Management Agency spokesman says it appears that a single tornado caused the damage in those two counties and Lamar County. Hundreds of homes are damaged in Forrest County, along with a couple dozen in the other two.
On the campus of the university, trees were snapped in half around the heavily damaged Alumni House where part of the roof was ripped away. The university says no one was hurt but that it was under a state of emergency, anyone away from campus should stay away until further notice.
Emergency officials say an apparent tornado has caused significant damage in Hattiesburg, Miss., after passing along a main road.

He said the damage was still being evaluated, but that the storm passed along a main Hattiesburg thoroughfare.
National Weather Service meteorologist Joanne Culin says there have also been reports of injuries in Marion County.
