On March 18,1925,one of the deadliest tornado outbreaks in recorded history generated at least twelve significant tornadoes and spanned a large portion of the midwestern and southern United States. In all,at least 751 people were killed and more than 2,298 were injured,making the outbreak the deadliest tornado outbreak,March 18 the deadliest tornado day,and 1925 the deadliest tornado year in U.S. history. The outbreak generated several destructive tornadoes in Missouri,Illinois,and Indiana on the same day,as well as significant tornadoes in Alabama and Kansas. In addition to confirmed tornadoes,there were undoubtedly others with lesser impacts,the occurrences of which have been lost to history.
The 1974 Super Outbreak was the second-largest tornado outbreak on record for a single 24-hour period,just behind the 2011 Super Outbreak. It was also the most violent tornado outbreak ever recorded,with 30 F4/F5 tornadoes confirmed. From April 3–4,1974,there were 148 tornadoes confirmed in 13 U.S. states and the Canadian province of Ontario. In the United States,tornadoes struck Illinois,Indiana,Michigan,Ohio,Kentucky,Tennessee,Alabama,Mississippi,Georgia,North Carolina,Virginia,West Virginia,and New York. The outbreak caused roughly $843 million USD in damage,with more than $600 million occurring in the United States. The outbreak extensively damaged approximately 900 sq mi (2,331 km2) along a total combined path length of 2,600 mi (4,184 km). At one point,as many as 15 separate tornadoes were occurring simultaneously.
A deadly tornado outbreak occurred in Central Texas during the afternoon and evening of May 27,1997,in conjunction with a southwestward-moving cluster of supercell thunderstorms.

The Central Plains were hit by two significant outbreaks on May 22 and May 24,the first outbreak of which produced a very large and violent tornado in Hallam,Nebraska. The Ohio Valley was affected by one of the largest tornado outbreaks ever during the Memorial Day weekend on May 29–30.
This page documents notable tornadoes and tornado outbreaks worldwide in 2006. Strong and destructive tornadoes form most frequently in the United States,Bangladesh,and Eastern India,but they can occur almost anywhere under the right conditions. Tornadoes also develop occasionally in southern Canada during the Northern Hemisphere's summer and somewhat regularly at other times of the year across Europe,Asia,Argentina,Brazil and Australia. Tornadic events are often accompanied with other forms of severe weather,including strong thunderstorms,strong winds,and hail.
Severe weather is any dangerous meteorological phenomenon with the potential to cause damage,serious social disruption,or loss of human life. Types of severe weather phenomena vary,depending on the latitude,altitude,topography,and atmospheric conditions. High winds,hail,excessive precipitation,and wildfires are forms and effects of severe weather,as are thunderstorms,downbursts,tornadoes,waterspouts,tropical cyclones,and extratropical cyclones. Regional and seasonal severe weather phenomena include blizzards (snowstorms),ice storms,and duststorms.

On February 10–11,2009,a broad-scale damaging wind event and small tornado outbreak affected the Central and Eastern United States. During the two-day period,14 tornadoes touched down in seven states. Oklahoma was struck by six tornadoes,the most of any state. The six tornadoes in Oklahoma also tied the record for the most tornadoes ever recorded in the state during the month of February,which would later be broken in 2023.

Tornadoes also appear regularly in neighboring southern Canada during the Northern Hemisphere's summer season,and somewhat regularly in Europe,Asia,and Australia.
From April 4–5,2011,a large-scale damaging wind event and tornado outbreak affected the Southern and Eastern parts of the United States. The system produced a large serial derecho windstorm that caused thousands of reports of wind damage and several embedded tornadoes. Power outages were extensive across the area and tree damage was severe. Several people were killed and injured by falling trees and branches as the storm passed through. Damaging tornadoes touched down in Arkansas,Kentucky,and Mississippi. The storm continued into the early hours of the morning causing more wind damage along the East Coast along with a few more tornadoes. It is reportedly one of the most prolific damaging wind events on record. The outbreak was the first in a series of devastating tornado outbreaks in the month of April 2011,which would culminate near the end of the month with the largest tornado outbreak ever recorded.
From April 14–16,2011,a tornado outbreak,among the largest recorded tornado outbreaks in U.S. history,produced 178 confirmed tornadoes across 16 states,resulting in severe destruction on all three days of the outbreak. A total of 38 people were killed from tornadoes and an additional five people were killed as a result of straight-line winds associated with the storm system. The outbreak of severe weather and tornadoes led to 43 deaths in the Southern United States. This was the largest number of fatalities in an outbreak in the United States since the 2008 Super Tuesday tornado outbreak. It is locally referred to as the "Forgotten Outbreak" in Alabama as it was vastly overshadowed by the 2011 Super Outbreak less than two weeks later.

Other destructive tornadoes occurred in Arkansas,Georgia,Kentucky,Louisiana,New York,and Virginia,with storms also affecting other states in the Southern and Eastern United States. In total,360 tornadoes were confirmed by NOAA's National Weather Service (NWS) and Government of Canada's Environment Canada in 21 states from Texas to New York to southern Canada. Widespread and destructive tornadoes occurred on each day of the outbreak. April 27 was the most active day,with a record 216 tornadoes touching down that day from midnight to midnight CDT. Four of the tornadoes were rated EF5,which is the highest ranking on the Enhanced Fujita scale;typically these tornadoes are recorded no more than once a year.
This page documents the tornadoes and tornado outbreaks of 2012.
