Шаблон:Short description Шаблон:Infobox storm As Hurricane Isaias moved up the East Coast of the United States, a damaging outbreak of 39 tornadoes impacted areas from South Carolina to Connecticut between August 3–4, 2020. The most significant tornado of the outbreak was a large and intense EF3 tornado that obliterated a mobile home park near Windsor, North Carolina, killing two and injuring 14. This was the strongest tornado in the United States to be spawned by a tropical cyclone since 2005. In the end, the outbreak killed two and injured 26.

Meteorological synopsis

Файл:Isaias 2020-08-03 1815Z.jpg
Hurricane Isaias intensifying as it approached its final landfall in The Carolinas on August 3.

After weakening to a tropical storm southeast of Florida, Isaias quickly re-intensified to hurricane status as it approached its final landfall point of Ocean Isle Beach, North Carolina on August 3.[1] A cold front and upper-level trough that was influencing the storm's movement enhanced the shear profiles across the region and a slight risk for severe weather was issued by the Storm Prediction Center (SPC) in their 1300 UTC update for Northeastern South Carolina and Northeastern North Carolina. Numerous embedded low-topped supercells formed overnight, producing many tornadoes and causing widespread damage, primarily to the north and east of the center of Isaias.[2]

With the tornado outbreak already underway and likely to continue, the SPC issued an enhanced risk in their 1300 UTC update from the Northeastern Delmarva Peninsula to the Tri-State area on August 4, east of the forecast track where wind shear was maximized. Numerous tornadoes, a few of which were strong, continued to touch down throughout the morning before abruptly ceasing around midday after the storm moved into New England and transitioned into an extratropical cyclone. In the end, a total of 109 tornado warnings were issued by various National Weather Service offices across a swath of 12 states due to Hurricane Isaias.[3]
