New Orleans Louisiana Hit With Multiple Tornado Warnings and Catastrophic Flooding as Tropical Storm Arthur Remnants Unleash Overnight and Morning Chaos

NEW ORLEANS, LOUISIANA — An incredibly active overnight and morning severe weather event is ongoing across lower Louisiana Thursday June 18, with multiple Tornado Warnings and catastrophic flooding rains hammering New Orleans, Laplace, Slidell, and the surrounding parishes as Tropical Storm Arthur remnants continue producing life-threatening conditions across the same areas devastated by Hurricane Ida in 2021.

Multiple Tornado Warnings Active Across New Orleans Metro

Live radar shows multiple simultaneous warning polygons active across the New Orleans metro Thursday morning. An orange Tornado Warning polygon covers the New Orleans and Estelle corridor along Interstate 10, with a yellow Severe Thunderstorm Warning extending from Laplace westward. A broader green Flash Flood Warning covers Thibodaux, Gray, Houma, and the surrounding Lafourche and Terrebonne Parish region.

Extreme reflectivity returns in red and white are concentrated directly over New Orleans and Laplace, indicating the most intense rainfall and storm activity is centered on the metro area during the active morning warning period.

Flooding Rains Compounding Tornado Threat Across Lower Louisiana

The combination of simultaneous tornado warnings and flooding rains creates an extraordinarily dangerous situation for residents across lower Louisiana Thursday morning. Communities from Gonzales and Belle Rose southward through Thibodaux, Houma, Jean Lafitte, and Galliano are all under active warning coverage as the tropical remnant system continues pushing heavy rainfall and rotating storm bands through the region.

Storm chasers and meteorologists are noting the striking similarity between this morning’s event and conditions experienced during Hurricane Ida in 2021 across the same lower Louisiana parishes.

Residents Across New Orleans and Surrounding Parishes Must Take Immediate Action

Anyone in New Orleans, Laplace, Slidell, Thibodaux, and Houma must take tornado shelter immediately if under an active Tornado Warning and avoid all flooded roadways as rising water continues across the region. This is an ongoing life-safety event with multiple hazards occurring simultaneously across lower Louisiana Thursday morning.
