This is a list of notable microbursts.
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, 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.
In meteorology, a downburst is a strong downward and outward gushing wind system that emanates from a point source above and blows radially, that is, in straight lines in all directions from the area of impact at surface level. It originates under deep, moist convective conditions like Cumulus congestus or Cumulonimbus. Capable of producing damaging winds, it may sometimes be confused with a tornado, where high-velocity winds circle a central area, and air moves inward and upward. These usually last for seconds to minutes. Downbursts are particularly strong downdrafts within thunderstorms.
The Late-May 1998 tornado outbreak and derecho was a historic tornado outbreak and derecho that began on the afternoon of May 30 and extended throughout May 31, 1998, across a large portion of the northern half of the United States and southern Ontario from southeastern Montana east and southeastward to the Atlantic Ocean. The initial tornado outbreak, including the devastating Spencer tornado, hit southeast South Dakota on the evening of May 30. The Spencer tornado was the most destructive and the second-deadliest tornado in South Dakota history. A total of 13 people were killed; 7 by tornadoes and 6 by the derecho. Over two million people lost electrical power, some for up to 10 days.
Severe storms in Australia refers to the storms, including cyclones, which have caused severe damage in Australia.
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.
The heat wave of 2006 derecho series were a set of derechos — severe winds with powerful thunderstorms — that occurred on July 17–21, 2006. The first storms hit a wide swath of north-central and northeastern North America that stretched from the Upper Midwest through much of Ontario and into the northeastern United States. Another round struck the middle Mississippi River Valley, including two derechos that hit St. Louis, Missouri. The storms left more than three million people without power, some more than once and some for weeks.
The Corn Belt derecho was a progressive derecho which affected a large area of the central United States on June 29, 1998. In the morning, thunderstorms, including a supercell, developed over South Dakota and tracked into central Iowa. As the thunderstorms reached central Iowa, a strong rear-inflow jet developed which caused the thunderstorm to take on a different characteristic, becoming a derecho. It traveled more than 600 miles in about ten hours, causing more than $125 million worth of widespread damage destruction, especially to crops, and was responsible for power outages to nearly a half a million people.
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.
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.
From May 3 to May 11, 2003, a prolonged and destructive series of tornado outbreaks affected much of the Great Plains and Eastern United States. Most of the severe activity was concentrated between May 4 and May 10, which saw more tornadoes than any other week-long span in recorded history; 335 tornadoes occurred during this period, concentrated in the Ozarks and central Mississippi River Valley. Additional tornadoes were produced by the same storm systems from May 3 to May 11, producing 363 tornadoes overall, of which 62 were significant. Six of the tornadoes were rated F4, and of these four occurred on May 4, the most prolific day of the tornado outbreak sequence; these were the outbreak's strongest tornadoes. Damage caused by the severe weather and associated flooding amounted to US$4.1 billion, making it the costliest U.S. tornado outbreak of the 2000s. A total of 50 deaths and 713 injuries were caused by the severe weather, with a majority caused by tornadoes; the deadliest tornado was an F4 that struck Madison and Henderson counties in Tennessee, killing 11. In 2023, tornado expert Thomas P. Grazulis created the outbreak intensity score (OIS) as a way to rank various tornado outbreaks. The tornado outbreak sequence of May 2003 received an OIS of 232, making it the fourth worst tornado outbreak in recorded history.
The 2010 Bronx tornado was a rare EF1 tornado which struck the Bronx in New York City, United States, touching down there on July 25, 2010 and traveled 1 mi (1.6 km). The tornado, which was the second ever tornado recorded in the Bronx, touched down around 2:55 p.m. EDT in Riverdale, located within the Bronx, causing damage to buildings, trees, cars, and power lines. Seven people were injured along its track due to broken glass. The tornado lifted around 3:00 p.m. EDT while still within the Riverdale neighborhood.
This page documents the tornadoes and tornado outbreaks of 2011. Extremely destructive tornadoes form most frequently in the United States, Bangladesh, Brazil and Eastern India, but they can occur almost anywhere under the right conditions. Tornadoes also appear regularly in neighboring southern Canada during the Northern Hemisphere's summer season, and somewhat regularly in Europe, Asia, and Australia.
The 2010 New Year's Eve tornado outbreak was a three-day-long tornado outbreak that impacted the central and lower Mississippi Valley from December 30, 2010 to January 1, 2011. Associated with a low pressure system and a strong cold front, 37 tornadoes tracked across five states over the length of the severe event, killing nine and injuring several others. Activity was centered in the states of Missouri and later Mississippi on December 31. Seven tornadoes were rated EF3 on the Enhanced Fujita Scale; these were the strongest during the outbreak. Non-tornadic winds were recorded to have reached as high as 80 mph (130 km/h) at eight locations on December 31, while hail as large as 2.75 in (7.0 cm) was documented north-northeast of Mansfield, Missouri. Overall, damage from the outbreak totaled US$123.3 million, most of which was related to tornadoes. This is the most prolific tornado outbreak in Missouri in the month of December.
The June 2012 Mid-Atlantic and Midwest derecho was one of the deadliest and most destructive fast-moving severe thunderstorm complexes in North American history. The progressive derecho tracked across a large section of the Midwestern United States and across the central Appalachians into the mid-Atlantic states on the afternoon and evening of June 29, 2012, and into the early morning of June 30, 2012. It resulted in a total of 22 deaths, millions of power outages across the entire affected region, and a damage total of US$2.9 billion which exceeded that of all other derecho events aside from the August 2020 Midwest derecho. The storm prompted the issuance of four separate severe thunderstorm watches by the Storm Prediction Center. A second storm in the late afternoon caused another watch to be issued across Iowa and Illinois.
A significant and destructive tornado outbreak that affected parts of the Midwestern United States and lower Great Plains in mid-May 2013. This event occurred just days after a deadly outbreak struck Texas and surrounding southern states on May 15. On May 16, a slow moving trough crossed the Rockies and traversed the western Great Plains. Initially, activity was limited to scattered severe storms; however, by May 18, the threat for organized severe thunderstorms and tornadoes greatly increased. A few tornadoes touched down that day in Kansas and Nebraska, including an EF4 tornado near Rozel, Kansas. Maintaining its slow eastward movement, the system produced another round of severe weather nearby. Activity significantly increased on May 19, with tornadoes confirmed in Oklahoma, Kansas, Iowa, Missouri, and Illinois. In Oklahoma, two strong tornadoes, one rated EF4, caused significant damage in rural areas of the eastern Oklahoma City metropolitan area; two people lost their lives near Shawnee. The most dramatic events unfolded on May 20 as a large EF5 tornado devastated parts of Moore, Oklahoma, killing 24 people. Thousands of structures were destroyed, with many being completely flattened. Several other tornadoes occurred during the day in areas further eastward, though the majority were weak and caused little damage.
On the morning and into the early afternoon of June 3, 2020, a powerful derecho crossed the U.S. states of Pennsylvania and New Jersey, resulting in four fatalities. It was the deadliest derecho event in the region since 1950.
This page documents notable tornadoes and tornado outbreaks worldwide in 2022. Strong and destructive tornadoes form most frequently in the United States, Argentina, Brazil, Bangladesh, and Eastern India, but 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, Australia and New Zealand. Tornadic events are often accompanied by other forms of severe weather, including strong thunderstorms, strong winds, and hail. Worldwide, 32 tornado-related deaths were confirmed: 23 in the United States, three in China, two each in Poland and Russia, and one each in the Netherlands and Ukraine.
A significant late-season tornado outbreak took place on November 4, 2022, across Northeast Texas, southwestern Arkansas, southeastern Oklahoma, and northwestern Louisiana with multiple large, destructive tornadoes occurring over a span of several hours. Major damage was reported in Sulphur Springs, Powderly, Caviness, Paris, Cason, Daingerfield, Athens, New Boston, Texas, and Idabel, Oklahoma, with the latter two communities being placed under tornado emergencies. Two fatalities occurred in Cason, Texas, and Pickens, Oklahoma respectively. Numerous PDS tornado warnings were issued as well. An additional tornado embedded within a narrow, but intense line of showers with damaging winds was also confirmed in Illinois the following morning as the system progressed eastward. Strong winds affected most of the western Great Lakes throughout the day before moving into Canada that evening. Two fatalities and at least 34 injuries were confirmed from tornadoes, and an additional fatality occurred near Stilwell, Oklahoma from drowning.
This is a list of notable tornadoes and tornado outbreaks worldwide in 2023. Strong, destructive tornadoes form most frequently in the United States, Argentina, Brazil, Bangladesh and East India, but can occur almost anywhere. Tornadoes develop occasionally in southern Canada during the Northern Hemisphere's summer, and at other times of the year across Europe, Asia, Argentina, Australia and New Zealand. They are often accompanied by other forms of severe weather, including thunderstorms, strong winds, and large hail. Worldwide, 116 tornado-related deaths were confirmed – 83 in the United States, 12 in China, nine in Indonesia, eight in Myanmar, three in Turkey, and one in Saudi Arabia.
A multi-day period of significant tornado activity along with significant derechos occurred across the Midwestern United States and the Mississippi Valley as well as an additional tornado in the Canadian province of Quebec. From May 19–27, 2024, two derechos occurred and tornadoes were reported across large portions of the Central United States, with multiple Particularly Dangerous Situation (PDS) watches issued across the sequence. On May 19, strong tornadoes occurred with isolated supercells in Colorado and Oklahoma while a derecho produced widespread wind damage and weak tornadoes across Kansas into the early morning hours of May 20. Limited tornadic activity took place on May 20, but another outbreak along with widespread damage struck mainly Iowa and Wisconsin on May 21. Five fatalities were confirmed with a large, violent, long-tracked EF4 tornado that went through Greenfield, Iowa. Scattered to widespread severe weather and tornadoes occurred over the next two days, including an EF2 tornado that injured 30 people on the west side of Temple, Texas. Another derecho formed in southwestern Nebraska late on May 23 and moved eastward, producing widespread wind damage and weak tornadoes through Nebraska and Iowa and northwestern Illinois before withering away in the northern part of the state during the morning hours of May 24.
