The unusual summertime pattern that brought intense heat to the Midwest and East, and our days'-long bouts with thunderstorms in the Northwest is affecting Poland as well.

A viewer near Warsaw captured this video of one tornado in particular.

Here is the Associated Press story on what happened:

WARSAW, Poland (AP) - A freak wave of summer tornadoes has struck northern and western Poland, killing at least one person and injuring another 10 people.

An area around Bory Tucholskie forest, a national park and popular tourist destination, was hit by a twister between 800 and 1,000 meters (875-1,100 yards) wide. More than 400 hectares (nearly 1,000 acres) of woodland were flattened in the area, authorities said, and more than 100 houses destroyed.

Power lines were downed and roads were closed as hundreds of firefighters worked to clear away fallen trees. Some trains had to make detours after debris fell onto tracks.

Firefighter Mieczyslaw Torlop told the TVN station that one man was killed in the village of Wycinki after being crushed by his house, which collapsed.

Tornadoes can strike anywhere in the world, but the United States by far and away gets the most of any other nation.

That's due to our unique geography that allows cold air from Canada to frequently clash with warm, moist air from the Gulf of Mexico, providing the required ingredients for supercell storm development and making a regular battleground of the Midwest. The flat terrain also allow air to flow freely with little interference from topography.
