One Czech TV station said the tornado may have been a F3 or F4 on the Fujita scale, rated at "significant" to "severe" damage. Meteorologist Michal Žák said it was "probably the strongest tornado in recent [Czech]history" and very uncommon in Europe reports RT.
This major and rare tornado in Europe comes only days after powerful storms ripped through Belgium, including a tornado that obliterates almost 100 homes in country's south.
