What type of clouds do tornadoes form inside?
Funnel clouds. A tornado is often made visible by a distinctive funnel-shaped cloud. Commonly called the condensation funnel, the funnel cloud is a tapered column of water droplets that extends downward from the base of the parent cloud.
Is a tornado just a cloud?
Tornadoes come in many shapes and sizes, and they are often visible in the form of a condensation funnel originating from the base of a cumulonimbus cloud, with a cloud of rotating debris and dust beneath it.
How can you tell if there is a tornado cloud?
The first sign is thunderheads: puffy cumulus or cumulonimbus clouds. The wall clouds and funnels will form right beneath them, so check there for any organized rotation. Watch the storm base closely, and look for persistent lowered areas—the lower they are, the better the chance of a tornado.
Where do F5 tornadoes occur?
Since 1950, Canada has had one tornado officially rated an F5. Outside the United States and Canada, seven tornadoes have been rated F5/EF5 or equivalent: two each in France, Germany, and Italy and one in Russia.
What happens just before a tornado?
Before a tornado strikes, the wind may die down and the air may become very still. A loud roar similar to a freight train may be heard. An approaching cloud of debris, even if a funnel is not visible.
What was the wind speed of a F5 tornado?
On the Fujita Scale, an F5 tornado has estimated wind speeds of 261-318 mph and is defined as having incredible damage in which strong frame houses can be leveled and swept off of foundations, automobile-sized objects can be lifted up into the air, and trees are usually debarked.

Where did the F5 tornado happen in Canada?
However, the population in the Canadian prairies is sparse so it’s harder to rate the damage that would classify a tornado as an EF5. An F5 tornado took place in Elie, Manitoba on June 22, 2007. At first, scientists thought it was an F4, but after further studies, the twister proved to be an F5.
Are there any EF5 tornadoes in the United States?
Since the implementation of the Enhanced Fujita scale on February 1, 2007, there have been nine officially rated EF5 tornadoes in the United States from May 4th, 2007-May 20th, 2013 to date, while previously fifty tornadoes were officially rated F5 on the original Fujita scale from May 11th, 1953-May 3rd, 1999.
Which is the most intense tornado on the Fujita scale?
The scale ranks tornadoes from F0 to F5, with F0 being the least intense and F5 being the most intense. F5 tornadoes were estimated to have had maximum winds between 261 mph (420 km/h) and 318 mph (512 km/h). [nb 1] Following two particularly devastating tornadoes in 1997 and 1999, engineers questioned the reliability of the Fujita scale.
