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. | |||||||||||
