[edit] F5 tornadoes in Canada

Canadian tornadoes tend to be less deadly in part due to sturdier buildings, made for colder weather. The F4 tornado that struck a densely populated area of Edmonton, Alberta, killing 27, may have been rated an F5 due to greater damage had it struck a US city of similar size.

[edit] Largest outbreak of tornadoes

The Super Outbreak, in which 149 tornadoes affected 13 states and one Canadian province on April 3 - 4, 1974. The outbreak also produced an unprecedented number of large, long-track, and intense tornadoes; 6 F5 and 24 F4 tornadoes were observed.

[edit] Highest (observed) winds in a tornado

During the F5 tornado that moved into Oklahoma City on May 3, 1999, a mobile doppler radar situated near the tornado measured winds of 301 +/- 20 mph(484 +/- 32 km/h) (Center for Severe Weather Research) inside the funnel.

Winds were measured at 257-268 mph (414-431 km/h) using portable doppler radar in the Red Rock Tornado during the Andover, Kansas Tornado Outbreak. Though these winds are possibly indicative of an F5 strength tornado, this particular tornado's path never encountered any significant structures and caused minimal damage. Thus it was rated an F4.

[edit] Fastest ground speed (movement)

73 mph (117 km/h) from the Tri-State Tornado (other weak tornadoes have approached or exeeded this speed, but this is the fastest forward movement observed in a major tornado).

[edit] fastest tornado(and longest location)

The longest track single tornado is thought to be the Tri-State Tornado, which traversed 425 miles an hr in about 3.5 hours.

[edit] Widest damage width

The widest tornado on record was the Wilber/Hallam, Nebraska tornado during the outbreak of May 22, 2004, with a width of 2.5 miles (4 km) at its peak.

[edit] Costliest tornado

The Oklahoma City tornado of May 3, 1999 caused $1.2 billion (USD) in damage. This was the first time in history that damage from a single tornado exceeded one billion present-day dollars.

Normalized for wealth and inflation, the St. Louis-East St. Louis Tornado is by far the most destructive and costliest tornado, with damages estimated at $2.9 billion (1997 USD).

[edit] Last tornado event to kill more than 40 people in the U.S.

Oklahoma Tornado Outbreak of May 3, 1999 - 245 dead

[edit] Least deadly tornado decade (Canada)

There was no tornado fatalities in Canada in the 1990's.[citation needed]

[edit] First confirmed tornado and first tornado fatality in the U.S.

[edit] Deadliest tornado of the 80s

May 22, 1987 - Saragosa, Texas - 30 dead

[edit] Biggest outbreak in the fall

92 tornadoes broke out in 41 hours of continuous tornado activity from November 21 to 23, 1992. Many other very large outbreaks have occurred in the fall, especially in November.

[edit] Longest span without a tornado rated F5

As of December 5, 2006, it has been more than 7 1/2 years since the United States has had an F5 tornado. The last hit near Oklahoma City during the May 3, 1999 event.

[edit] Latest Date for First Tornado of Year in US

The first confirmed tornado of 2003 hit in Mississippi on February 15.

[edit] Most tornadoes spawned from a hurricane

123 tornadoes spun out of Hurricane Frances upon landfall in Florida in September 2004. The old record was 115 from Hurricane Beulah in 1967.

[edit] Exceptional coincidence

A small town in Kansas called Codell was hit by a tornado on the exact same date three years straight. A tornado hit on May 20, 1916, 1917, and 1918. The U.S. has 100,000 thunderstorms a year; less than 1% produce a tornado. The odds of this coincidence occurring again is extremely small.
