Another round of strong-to-severe thunderstorms rocked the Southeast on Sunday night into Monday morning, leading to widespread power outages, and a deadly EF-4 tornado in Mississippi. Several strong storms were reported in Mississippi, Alabama, Louisiana, Georgia, Florida and Texas on Sunday afternoon and Sunday night. Damaging winds were the primary threat noted with the majority of the storms, although large hail and tornadoes were observed as well. Perhaps the most active time period, however, came late on Monday morning as the powerful line of storms moved into central Florida, leading to several tornado reports near Tampa and Orlando. Damaging winds were also observed with these storms. https://twitter.com/WeatherNation/status/1252278911490125829?s=20 https://twitter.com/WeatherNation/status/1252270044119089154?s=20 The strongest individual storm from this severe weather outbreak, however, likely was a powerful supercell thunderstorm that moved through southern Mississippi on Sunday. A long-track tornado moved through southern Mississippi on Sunday night, leaving behind a wide path of damage.
