NEW ORLEANS - The National Weather Service has updated to ten the number of tornadoes that hit Louisiana Tuesday.

Among the twisters was a powerful EF-3 that the National Weather Service upgraded Thursday afternoon.  It struck parts of Assumption Parish where damage was wide-spread. 

Three EF-2 tornadoes were responsible for the extreme damage in Convent and LaPlace.  A similar-sized tornado also hit  in Livingston Parish, the NWS said.  

Meteorologist Phil Grigsby told The Associated Press Thursday the tornado that destroyed a Convent trailer park was an EF-2 tornado, with winds of 111-135 mph. 

The five other tornadoes were an EF-0, with winds of 65-85 mph. They were in Lacombe, Kenner, Madisonville, Manchac, Montpelier, and Prairieville.

Grigsby said survey teams are investigating several other suspected sites for tornado damage.
