A supercell is a thunderstorm characterized by the presence of a mesocyclone, a deep, persistently rotating updraft. Due to this, these storms are sometimes referred to as rotating thunderstorms. Of the four classifications of thunderstorms (supercell, squall line, multi-cell, and single-cell), supercells are the overall least common and have the potential to be the most severe. Supercells are often isolated from other thunderstorms, and can dominate the local weather up to 32 kilometres (20 mi) away. They tend to last 2–4 hours.
Supercells are often put into three classification types: classic (normal precipitation level), low-precipitation (LP), and high-precipitation (HP). LP supercells are usually found in climates that are more arid, such as the high plains of the United States, and HP supercells are most often found in moist climates. Supercells can occur anywhere in the world under the right pre-existing weather conditions, but they are most common in the Great Plains of the United States in an area known as Tornado Alley. A high number of supercells are seen in many parts of Europe as well as in the Tornado Corridor (es) of Argentina, Uruguay and southern Brazil. (Full article...)Selected tornado list -

Selected tornado year -
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.
In 2006, there were 1,333 reported tornadoes in the US (of which 1,103 tornadoes were confirmed), with 67 reported fatalities (about half of those recorded in Tennessee). In addition, four other tornado-related deaths were reported in Europe - all of them in Germany where 119 tornadoes were confirmed, 12 deaths in Japan, nine deaths in China, three deaths in Vietnam, and one tornado fatality has been reported in Canada, in the province of Manitoba for a worldwide total of 94.

2024 tornado activity
From April 26–28, 2024, a very large, deadly and destructive tornado outbreak occurred across the Midwestern, Southern, and High Plains regions of the United States, primarily on April 26 and 27. The Storm Prediction Center (SPC) first issued an enhanced risk for the Plains on April 26, as a broad upper-trough moved eastwards, with tornadic activity erupted in the states of Iowa and Kansas that evening. A moderate risk was issued by the SPC on April 27 for areas further south in Oklahoma, where a deadly nocturnal event unfolded with many supercell thunderstorms and tornadoes tracking over towns several times. Millions were put under a particularly dangerous situation (PDS) tornado watch on April 27, and several PDS tornado warnings were issued that night as numerous strong tornadoes touched down. The outbreak served as the beginning of a broader 16-day period of constant severe weather and tornado activity across the United States that would continue until May 10.
Damaging tornadoes occurred across many states over the two days of the outbreak. On April 26, a tornado in Lancaster County, Nebraska, injured three people, which touched down in the northeastern outskirts of Lincoln, Nebraska. At least six fatalities were attributed to the tornadoes, with more than 156 people injured. At least twenty eight tornadoes were confirmed, with ten in Iowa and one each in Nebraska and Texas. Significant damage was also reported in Elkhorn and near Bennington, Nebraska, from an EF3 wedge tornado that prompted a tornado emergency. Another long-tracked tornado in Iowa that impacted Shelby County, Iowa, prompted two tornado emergencies as well. On April 27, several tornadoes occurred in Texas, Oklahoma, and Kansas. Overnight, a significant tornado passed near Holdenville, Oklahoma, causing at least two fatalities and four injuries. A tornado impacted Sulphur, Oklahoma, as well, causing at least 30 injuries.
The outbreak was the largest since a similarly large and deadly outbreak the year prior, although this one was spread out over a slightly larger time period and was not as deadly, with only 6 people dying as a result of this outbreak, and over 150 people being injured. With a grand total of 138 tornadoes over a two-day period, the tornado outbreak gained 87 points on the outbreak intensity score. (Full article...)Tornado anniversaries

The 1999 Sydney hailstorm was the costliest natural disaster in Australian insurance history, causing extensive damage along the east coast of New South Wales. The storm developed south of Sydney on the afternoon of Wednesday, 14 April 1999, and struck the city's eastern suburbs, including the central business district, later that evening.
The storm dropped an estimated 500,000 tonnes of hailstones in its path. The insured damage bill caused by the storm was over A$1.7 billion (equivalent to $3.8 billion in 2022), with the total bill (including uninsured damage) estimated to be around $2.3 billion. It was the costliest single natural disaster in Australian history in insured damage, surpassing the $1.1 billion in insured damage caused by the 1989 Newcastle earthquake. Lightning also claimed one life during the storm, and the event caused approximately 50 injuries. (Full article...)Topics
