Triggered by a slow-moving upper-level trough interacting with moist, unstable air from the Gulf of Mexico, the outbreak produced 35 confirmed tornadoes, including a violent EF4 that tore through Rolling Fork, Midnight, and Silver City, Mississippi with peak winds of 195 mph. This EF4 tornado alone caused catastrophic damage and multiple fatalities and brought tornado emergencies ahead of widespread destruction.<br>\n",

     "Over the four-day span, the system also unleashed damaging straight-line winds, large hail, and flooding. In total, the outbreak resulted in 23 fatalities (plus two from non-tornadic causes), over 230 injuries, and an estimated $1.9 billion in damage. The event was notable not only for its intensity but also for its geographic breadth and the prolonged nature of the severe weather threat.\n",
