| Brief Description: EVENT NARRATIVE: Wind speeds were estimated between 110 and 120 mph, or on the low end of EF2. This tornado was spawned by the same storm that produced the Youngsville tornado. The tornado began southwest of the intersection of Poydras Highway and Eunice Road and moved northeast, ending past Nursery Highway. Several brick homes had roofs removed near the highs school, with one home losing most of its second floor. A total of 44 homes were damaged or destroyed, with 80 homes impacted by the tornado. Three injuries occurred in a small brick home where the roof blew off, causing a brick wall and other debris to land on them. Several trees were damaged or uprooted. This was the strongest tornado in southwest Louisiana since the November 23 2004 tornado outbreak. EPISODE NARRATIVE: An approaching cold front resulted in showers and thunderstroms across southwest Louisiana, some of which became severe. Several tornadoes touched down across Acadiana. | |||||||||||
