Severe weather since 1950:

In 1997, severe storms snapped a power pole and downed several power lines in New Orleans in the early pre-dawn hours. Around 2 inches of heavy rainfall produced street flooding in St. Tammany and upper Jefferson Parishes. 

In 2000, severe storms produced minor wind damage in Slidell and Poplarville in the evening hours. 

In 2007, a significant EF-2 rated tornado developed near Westwego and hit an occupied hotel, injuring 10; then crossed the Mississippi River into Harahan area and into New Orleans, lifting in Gentilly near Pontchartrain Park. One fatality occurred - an elderly woman living in temporary Katrina housing in Gentilly, just days before moving back into her permanent home. In total, 1 fatality, 34 injuries and around $5 million in damage.
