Greek tornado outbreak of 2019

the Greek tornado outbreak and flooding of 2019 was the largest known tornado outbreak in Greek history, occurring on July 29-31, 2019. The tornado outbreak was the result of the remnants of a medicane moving through the Greek mainland and neighboring islands, as well as Anatolia. The slow moving remnants also caused catastrophic flooding in Greece and Anatolia.

Meteorological history
The Italian government began tracking a disturbance in the Adriatic Sea on July 22, as it moved south it attained tropical cyclone status on July 23 when it obtained a strong centralized circulation as well as winds of 45 mph. It continued south and briefly attained Category 1 hurricane strength winds early on July 25 before it made landfall near Split, Croatia. It rapidly weakened to a remnant low by the time it re-emerged into the Adriatic Sea on July 26, the storm accelerated motion south and exited the sea as a post-tropical low on July 28, the rather isolated thunderstorm activity formerly associated with the medicane then moved east and slowed down as they entered Greece early on the morning of July 29.

It rapidly developed rain coverage, and several thunderstorms developed rotation. At 8:42 am UTC that day, a EF0 tornado touchdown was confirmed near Patras, with a waterspout moving onshore at 12:28 pm UTC near Katsouli and briefly becoming a EF1 tornado. The Greek government issued a flood and severe weather watch, the first of it's kind, at 12:56 pm UTC for most of Greece, with the border regions with North Macedonia, Albania, Bulgaria and Turkey being excluded. It stated the possibility for "Widespread catastrophic flooding, damaging winds of up to 112 km/h, small hail and tornadoes".

At 5:22 pm UTC, a EF2 tornado would occur near Prousos, heavily damaging many homes in the area and killing 1 tourist from the Ukraine. Widespread street flooding was reported all over the country by this point, with the only possible safe areas for tornadoes being flooded.

At 5:41 pm UTC, the last tornado of July 29 was confirmed when a high-end EF2 tornado occurred in Arta, knocking out power to the city and destroying many older houses. The tornado was one of the strongest ever recorded in Greece.

On July 30, a supercell produced a EF1 tornado around 2:28 am UTC near Athens, the capital of Greece, minor roof damage was reported, with the bulk of EF1 damage occurring at a house where the roof sustained high-end EF1 damage.
