A twister lashed Oslo during the violent rains that hit the capital Saturday.

That the meteorological service. It is rare to experience twister in this country, but in 2004 swept one twister in Oslo that was so strong that it moved in several cars, brick houses, was tossed around and several trees and signs fallow.

State Meteorologist Olav Erikstad at the Meteorological Department said at the time NTB that waterspout a very unusual weather phenomenon in Norway, and that it is exceptional that waterspout came in over the developed area.

A waterspout occurs when the air on the ground is mild, and the air in altitude is very cold. When rising the hot air quickly, and thus arises a gap along the ground that must be filled. When this starts to rotate creates a twister.

On Bygdøy in Oslo fell Saturday 33.4 millimeters rainfall between 11 and 12 o’clock Saturday, almost half of what normally falls in the month of August.
