During the afternoon of April 27, 2011, a violent EF5 tornado touched down in eastern Mississippi, killing three people. Part of the historic 2011 Super Outbreak, the largest tornado outbreak on record, this was the first of four EF5 tornadoes to touch down that day and the first such storm in Mississippi since the 1966 Candlestick Park tornado. While on the ground for 30 minutes, it traveled along a 28.28-mile (45.51 km) path through four counties, leaving behind three deaths, eight injuries, and $1.1 million in damage.
The supercell thunderstorm that produced this tornado formed around 1:00 p.m. CDT south of Jackson, Mississippi. Traveling briskly to the northeast, it became severe within 25 minutes and potentially tornadic by 1:36 p.m. CDT. A tornado finally touched down at 2:30 p.m. CDT just east of the Philadelphia Municipal Airport. It quickly intensified and began producing EF5 damage by 2:38 p.m. CDT; extreme ground scouring, up to 2 feet (0.61 m) deep in places, occurred in northeastern Neshoba County. After crossing into Kemper County, the tornado obliterated a mobile home, killing all three inside. It reached EF5 strength a second time near the Kemper–Winston county line where extreme ground scouring again took place and pavement was scoured from roads. Extensive tree damage took place elsewhere along the track and it ultimately dissipated at 3:00 p.m. CDT about 6 miles (9.7 km) north of Mashulaville. (Full article...)Selected tornado list -
This page lists all the confirmed and probable tornadoes which have touched down in Canadian provinces & territories.
Experts have estimated that around 230 tornadoes occur in Canada each year, though only around 60 are formally confirmed. with most occurring in Southern Ontario, the southern Canadian Prairies and southern Quebec. Canada ranks as the second country in the world with the most tornadoes per year, after the United States of America. Of the average 60 confirmed tornadoes each year, Alberta and Saskatchewan both average between 14 and 18 tornadoes per season, followed by Manitoba and Ontario with normally between 8 and 14 tornadoes per season. Quebec is another recognized tornado-prone zone averaging between 4 and 8 tornadoes each year. Atlantic Canada and Interior British Columbia are also recognized tornado zones averaging between 0 and 4 tornadoes each year. The Canadian Territories are not typically seen as tornado-prone regions, however tornadoes can occur in the region. The peak season for tornadoes and severe thunderstorms in Canada is in the summer months, although tornadoes in Canada have occurred in spring, fall and very rarely winter.

- 1840 – the second-deadliest tornado in U.S. history destroyed the central and northern parts of Natchez, Mississippi and nearby areas, killing at least 317 people. Most of the deaths were in boats on the Mississippi River, which was experiencing high traffic at the time. The death toll may have been much higher, as there were unverified reports that hundreds of slaves were killed in Louisiana. The deaths of slaves in the pre-Civil War United States were not always counted.
- 1846 – A tornado devastated Grenada, Mississippi, killing at least 21 people. There were likely additional deaths later on as people succumbed to their injuries.

- 1882 – Deadly tornadoes touched down across Oklahoma and Arkansas. An F4 tornado destroyed much of McAlester, Oklahoma, killing 21 people. An F2 tornado destroyed much of a plantation near Silver, Arkansas, killing two people and hundreds of livestock. Another nine deaths were from other tornadoes.
- 1964 – A short-live but large and destructive F4 tornado struck the Anchor Bay area of Chester Township, Michigan, killing 11 people, injuring 224, and destroying 132 homes. Because of the high water table, few homes in the area had basements where people could take shelter, in spite of a 20-minute tornado warning.
- 1965 – An F4 destroyed 90% if Primrose, Nebraska, killing four people. The body of a truck was carried or rolled 2 miles (3.2 km). An F5 tornado completely swept away farms near Colome, South Dakota, resulting in one injury but no fatalities.
May 9
- 1876 – An F3 tornado moved through downtown Chicago and onto Lake Michigan, killing two people. A newspaper reporter wrote a detailed description of the tornado's multiple-vortex structure, including the presence of a downdraft at the center, a century before such mechanics were documented scientifically.
- 1927 – The third and most violent day of a three-day tornado outbreak resulted in 212 fatalities in the southern and Midwestern United States. An F4 tornado killed 98 people after destroying 31 blocks of Poplar Bluff, Missouri. Other tornadoes had large death tolls in Strong, Arkansas, Nevada, Texas, and Garland, Texas.

The 2006 Westchester County tornado was the strongest and largest tornado in Westchester County, New York since the 1904 Chappaqua tornado. It touched down there on Wednesday, July 12, 2006, and traveled 13 miles (21 km) into southwestern Connecticut during a 33-minute span through two states. The tornado touched down at 3:30 p.m. EDT (19:30 UTC) on the shore of the Hudson River before becoming a waterspout and traveling 3 mi (5 km) across the river. Coming ashore, the tornado entered Westchester County and struck the town of Sleepy Hollow at F1 intensity. After passing through the town, it intensified into an F2 tornado and grew to almost a one-quarter mile (400 m) in diameter. The tornado continued through the county, damaging numerous structures, until it crossed into Connecticut at 4:01 p.m. EDT (20:01 UTC). Not long after entering the state, it dissipated in the town of Greenwich at 4:03 p.m. EDT (20:03 UTC). When the tornado entered Westchester County, it was the eighth known tornado to either touch down or enter the county since 1950.
Two barns and a warehouse were destroyed, and a large stained-glass window was shattered. Numerous homes and businesses were damaged and thousands of trees were uprooted. There were no fatalities and only six minor injuries were associated with the storm. The cost of damages was estimated at $12.1 million. (Full article...)List of Featured articles and lists
