2014 Cyclone Quinn tornado outbreak (Ireland)

Additional information: Cyclone Quinn (2014)

NOTE: Cyclone Quinn was never a tropical cyclone.

Between March 17 and 20, 2014, much of southeastern Ireland was affected by tornadoes resulting from Cyclone Quinn, a very devastating European windstorm. Severe flooding and widespread fatalities were reported alongside the outbreak. While most of the tornadoes harmed very little urban infrastructure, a T10 (F5) tornado tracked through the heart of Dublin, destroying famous landmarks and killing hundreds.

The winter of 2013-14 had been an extremely abnormal winter for northern Europe. Dozens of snowstorms and freak windstorms had affected vast portions of the British Isles, France, Benelux, and Central Europe. However, by March, an extreme position of the Arctic jet stream fueled near record-breaking temperatures around the British Isles. This resulted in an uptick of the intensity of the storms. Notably, Cyclone Niall had rapidly intensified to a Category 5-equivalent windstorm in just a couple of days. Days later, Cyclone Patrick bombed from a gale-force windstorm to that of a Category 5-equivalent system off the coast of Galway, going on to inundate much of central Ireland. Additionally, this compounded on to a bitter, moist winter which had threatened Ireland's economy. On the morning of St. Patrick's Day, Cyclone Quinn came to life just offshore of Cork. As it moved towards shore, its very small size prompted an exceptional case of a bomb cyclone, with its winds rising over 100 miles per hour in 18 hours to those matching a Category 5 hurricane. With this came plenty of funnels across Quinn's circulation. Moving ashore near Waterford, Ireland, these funnels would go on to cause an outbreak rarely witnessed in modern history.
