A severe thunderstorm warning is a type of public warning for severe weather that is issued by weather forecasting agencies worldwide when one or more severe thunderstorms have been detected by Doppler weather radar, observed by weather spotters, or reported by an emergency management agency, law enforcement, or the general public. Unlike a watch, a warning is issued to areas in the direct path of active severe thunderstorms, that are expecting a direct impact typically within an hour. Severe thunderstorms can cause property damage and injury due to large hail, high winds, and flooding due to torrential rainfall. The exact criteria to issue a warning varies from country to country.
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. These storms produced 20 tornadoes, mainly along the Interstate 35 corridor from northeast of Waco to north of San Antonio. The strongest tornado was an F5 tornado that leveled parts of Jarrell, killing 27 people and injuring 12 others. Overall, 30 people were killed and 33 others were hospitalized by the severe weather.
Severe storms in Australia refers to the storms, including cyclones, which have caused severe damage in Australia. For comparison, a comprehensive list of all damaging storms can be found on the Australian Bureau of Meteorology website.
The Daulatpur–Saturia tornado occurred in Manikganj District, Bangladesh on 26 April 1989. There is great uncertainty about the death toll, but official estimates from the World Meteorological Organization indicate that it was devastating and that it killed approximately 1,300 people, which would make it the deadliest tornado in history. In 2022, this tornado's status as the deadliest tornado in history was challenged, claiming it did not kill more than 922 people. The tornado affected the cities of Daulatpur and Saturia the most, moving east through Daulatpur and eventually northeast into Saturia. Previously, the area that the tornado hit had been in a state of drought for six months.
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. The first day of the outbreak produced the most tornadoes; the second brought mainly high wind damage and rain or snow in most of the Northeast.
The tornado outbreak of April 9–11, 2009 was a tornado outbreak that affected large portions of the Southern United States on April 9–11, 2009. At least 5 people were killed by tornadoes including three in Mena, Arkansas and two in Murfreesboro, Tennessee just south of Nashville. A total of 85 tornadoes were confirmed over the two days. Three people were killed in Texas due to wildfires caused by strong winds stemming from the same storm system. This event is sometimes referred to as the Good Friday tornado outbreak of 2009.
In the early morning hours of April 4, 1981, an unusual and deadly anticyclonic F4 tornado struck West Bend, Wisconsin. It killed three people, and injured another 53. The tornado was largely unexpected and the storm that produced it did not display features of a typical severe storm. Because of this, the National Weather Service issued only a Severe Thunderstorm Warning prior to the tornado which caused local law enforcement to not sound the tornado sirens in time for residents to take shelter.
At approximately 11 pm local time, 13 April 2010, a severe storm struck parts of Bangladesh and eastern India. It lasted about 90 minutes, with the most intense portion spanning 30–40 minutes. As of 16 April, more than 140 deaths have been reported. At least 91 people died in the Indian state of Bihar, 44 in West Bengal, and 4 in Assam. In Bangladesh, five deaths and two hundred injuries were reported. Most of the deaths were women and children crushed when their huts were destroyed. Over 91,000 dwellings were destroyed in India and several thousand in Bangladesh; approximately 300,000 dwellings were at least partially damaged. Both mud and pucca housing was damaged by the storm. Nearly 500,000 people were left homeless or otherwise affected by the storm.
From May 21 to May 26, 2011, one of the largest tornado outbreaks on record affected the Midwestern and Southern regions of the United States. A six-day tornado outbreak sequence, most of the tornadoes developed in a corridor from Lake Superior southwest to central Texas, while isolated tornadoes occurred in other areas. An especially destructive EF5 tornado destroyed one-third of Joplin, Missouri, resulting in 158 deaths and over 1,000 injuries. The Joplin tornado was the deadliest in the United States since April 9, 1947, when an intense tornado killed 181 in the Woodward, Oklahoma, area. Tornado-related deaths also occurred in Arkansas, Kansas, Minnesota, and Oklahoma. Overall, the tornado outbreak resulted in 186 deaths, 8 of those non-tornadic, making it second only to the 2011 Super Outbreak as the deadliest since 1974. It was the second costliest tornado outbreak in United States history behind that same April 2011 outbreak, with insured damage estimated at $4–7 billion.
Near the end of 2012, a massive storm complex developed that produced both a tornado outbreak and a blizzard across the southern and eastern United States. On Christmas Day 2012, a tornado outbreak occurred across the Southern United States. This severe weather/tornado event affected the United States Gulf Coast and southern East Coast over a two-day span. It occurred in conjunction with a much larger winter storm event that brought blizzard conditions to much of the interior United States. In total, 31 tornadoes were confirmed by the National Weather Service in five states from Texas to North Carolina. All but one of the tornadoes that occurred during the outbreak touched down on December 25, with the other occurring the following day in North Carolina. Two of the tornadoes were destructive enough to be rated EF3 on the Enhanced Fujita Scale. At least 16 people died as a result of the related blizzard, and thousands were without power.
On November 17, 2013, the deadliest and costliest November tornado outbreak in Illinois history took shape, becoming the fourth-largest for the state overall. With more than 30 tornadoes in Indiana, it was that state's largest tornado outbreak for the month of November, and the second largest outbreak recorded in Indiana. Associated with a strong trough in the upper levels of the atmosphere, the event resulted in 77 tornadoes tracking across regions of the Midwest United States and Ohio River Valley, impacting seven states. Severe weather during the tornado outbreak caused over 100 injuries and eleven fatalities, of which eight were tornado related. Two tornadoes—both in Illinois and rated EF4 on the Enhanced Fujita scale—were the strongest documented during the outbreak and combined for five deaths. In addition to tornadoes, the system associated with the outbreak produced sizeable hail peaking at 4.00 in (10.2 cm) in diameter in Bloomington, Illinois, as well as damaging winds estimated as strong as 100 mph (160 km/h) in three locations.
The 2014 Nepal snowstorm disaster occurred in central Nepal on 14 October 2014 and resulted in the deaths of at least 43 people of various nationalities, including at least 21 trekkers. Injuries and fatalities resulted from unusually severe snowstorms and avalanches on and around the mountains of Annapurna and Dhaulagiri. The incident was said to be Nepal's worst trekking disaster.

A significant and deadly severe weather event that affected the Southeastern United States on March 3, 2019. Over the course of 6 hours, a total of 41 tornadoes touched down across portions of Alabama, Georgia, Florida, and South Carolina. The strongest of these was an EF4 tornado that devastated rural communities from Beauregard, Alabama, through Smiths Station, Alabama to Talbotton, Georgia, killing 23 people and injuring at least 100 others. Its death toll represented more than twice the number of tornado deaths in the United States in 2018 as well as the deadliest single tornado in the country since the 2013 Moore EF5 tornado. An EF3 tornado also destroyed residences to the east of Tallahassee in Leon County, Florida, and was only the second tornado of that strength in the county since 1945. Several other strong tornadoes occurred across the region throughout the evening of March 3 and caused significant damage. A large number of EF0 and EF1 tornadoes also touched down.
