The F4 tornado that hit Hamden, Connecticut in 1989 struck on July 10.
Yes. Moore, Oklahoma was hit by an F4 tornado on May 8, 2003.
The day the F4 tornado hit Edmonton, July 31, 1987, is known as Black Friday.
There was a deadly F4 tornado that likely hit the Auburndale area on April 4, 1966.
Picher, Oklahoma was hit by an EF4 tornado (same thing as an F4, just on a somewhat different scale) on May 10, 2008
Absolutely yes. In 2008 an EF4 tornado hit the town of Hautmont. In 1967 a tornado outbreak hit France,Belgium and Netherlands producing an F5 tornado in Palluel and an F4 tornado in Pommereuil with a width of 2.5 km (1.6 mi). On June 3, 1902 an F3/F4 tornado hit Javaugues reaching a width of 3 km (1.9 mi). (The largest on record in Europe) and finally in 1845 an F5 tornado hit the town of Montville, the strongest on record in Europe. In addition to these, weak tornadoes occur fairly regularly.
No, Colorado has never recorded an F5 or EF5 tornado, the strongest was an F4. The largest tornado (by path width) on record in Colorado was rated EF3.
Yes. Although no hurricane on record has produced an F5 tornado, two known hurricanes have produced F4 tornadoes. Hurricane Carla spawned an F4 tornado in Galveston, Texas on September 12, 1961. Hurricane Hilda spawned an F4 tornado that hit Larose, Louisiana on October 3, 1964.
No. First of all, there seems to be a some confusion here. The Oak lawn tornado outbreak was not a tornado, it was an outbreak of at least 45 tornadoes across the Midwest and Great Lakes regions. Second, the F4 tornado that struck Oak Lawn was not the only tornado in the area of Chicago. Among other events, an F3 tornado struck downtown Chicago in 1871, an F4 tornado hit Bolingbrook in 1976, and an F5 tornado hit Plainfield in 1990.
An F4 or higher tornado (the only higher rating being F5) is classified as violent.
The Goliad, Texas tornado was an F4.
If your house is hit by the full force of an F4 (now EF4) tornado it will probably be completely leveled. Even if you escape the worst of it (which can be surprisingly likely depending on the tornado) there will still likely be severe damage. The best place to be in an event like this, or any tornado, is in a storm cellar or basement.
