A tornado outbreak struck southern and central Poland on 15 August 2008. Overall, it killed four people. Tornadoes affected Opole Voivodeship, Silesian Voivodeship and Łódź Voivodeship. The European Storm Forecast Experiment issued a Level 3 which means there could potentially be a major severe thunderstorm outbreak. Tornado outbreak Multiple supercells formed in southern Poland on the afternoon of August 15, 2008 and produced several significant tornadoes that resulted in many casualties and significant damage. The main tornado-producer was a long-tracked right moving supercell with a BWER and a hook echo visible on radar which formed in southern Poland and moved north-northeastward, spawning several strong tornadoes. The outbreak began when a weak tornado touched down in Knurów causing little damage. While the first tornado was occurring, the main tornado-producer produced its first tornado, a large and violent multiple-vortex that struck the villages of Dolnica, Kopanina, Zimna Wódka, Kolonia Jaryszów, Balcarzowice, Błotnica Strzelecka and Dąbrówka with a total path of 20 km damaging or destroying hundreds of buildings and wounding 15 people, with a width of 500–1000 m before dissipating in a wooded area. It was given a rating of high-end F3/low-end F4. The supercell produced another multiple-vortex tornado near Piłka and struck the northern side of town, causing little damage. Northeast of Rusinowice the tornado quickly became large and destroyed a large swath of forest, its path still clearly visible on satellite imagery today. The tornado then hit the western suburbs of Kalina where it killed 1 person and caused more tree damage before it probably dissipated east of Herby, where the supercell either quickly recycled and produced a new F3 tornado that struck the city of Blachownia, or the same tornado continued into Blachownia. After the tornado that impacted Blachownia dissipated, the supercell produced an F2 tornado struck the town of Mykanów. This tornado flipped a bus while it was crossing a highway, and a video taken by one of the passengers can be seen on YouTube today. At 16:40 UTC the same supercell produced another multiple-vortex and non-fully condensed F3 which struck the west part of Radomsko, destroying or damaging about 100 houses on a path of about 4–5 km. Four other tornadoes touched down, including another F3 and an F2 before the main tornado-producing supercell decayed. Another F1 tornado touched down in Radom, likely associated with a different supercell, before activity on the 15th ended. The outbreak continued
