EF1 tornado in St. Tammany Parish, Louisiana

High resolution satellite analysis, ground survey, and radar imagery aided in confirming the existence of another tornado that tracked just south of the Interstate 12/10 interchange before crossing the Interstate near Military Road and impacting the neighborhoods along Crawford Landing Road. A localized area of tree damage that aligned along eastbound Exit 83 where branches and trunks were broken or bent east distinctly separates this damage from the damage path to the north and east. This tornado damage is being used as the starting point for the tornado as it aligns with the remainder of the damage path further east. As the tornado tracked east, scattered tree damage was reported across Country Club Blvd with numerous uproots, a few snaps, and many hardwood branches broken. Damage was relatively more sporadic as the tornado crossed near the Interstate interchange until damage became more apparent along Lake Village Blvd and into Crawford Landing Road. Thereafter, the tornado damage path across the Pearl River Wildlife Management Area became increasingly more apparent as the tornado appeared to intensify on high resolution satellite imagery. The tornado damage path was its widest and most intense just west of Perch Lake where the peak width was measured to be near 175 yards before exiting St. Tammany Parish and entering Hancock County along its 10 mile path. It had a peak intensity of EF-1 or 105 mph.

A strong upper level disturbance, surface low, and cold front produced a line of severe thunderstorms that pushed across Southeast Louisiana and Southern Mississippi in the morning and early afternoon hours of Wednesday, April 10, 2024. The line of severe thunderstorms produced strong straight line winds, extensive flash flooding in the New Orleans metro area and several tornadoes. The strongest tornado was an EF-2 tornado that impacted the city of Slidell in St. Tammany Parish, LA on the morning of the 10th. 7 tornadoes have been confirmed from this event. 4 of those 7 touched down and tracked across just the city of Slidell. At one point, as many as 3 of those 7 were on the ground at the same time. These tornadoes have been determined to range in strength from EFU to EF2 after NWS storm surveys and high resolution satellite analysis were conducted.
