Winter weather in 2017 kicked off with a winter storm from January 4-8. This winter storm causes six fatalities. [1] Around a week later, an ice storm causes 9 fatalities.[ citation needed ] Portland, Oregon saw the most snow in a single day in 20 years. [2] Around a week after that, a nor'easter from the Tornado outbreak of January 21-23, 2017 caused a death in Philadelphia, [3] It also resulted in 100 accidents in Quebec. [4] After a lull in activity, winter weather resumed on February 9, which caused a man to die in Manhattan. [5] New York City had record warmth the day before. [6] Then, another winter storm rode up the East Coast a few days later, killing two. [7] [8] Six thousand power outages occur in Nova Scotia. [9] A month later, a giant blizzard rode up the East Coast. At least 16 people were killed. [10] A record no-snow streak in Chicago was ended. [11] Another winter storm affected the Rocky Mountains in late April. Pueblo, Colorado saw 9200 power outages as a result, [12] and portions of Interstate 70 in Kansas shut down. [13] While mostly rain, a significant storm complex affected the Northeastern United States in late October. It caused over $100 million in damage, [14] and 1.3 million power outages. Maine set a record number of power outages. [15] However, the mountains of West Virginia record up to 8.4 inches (21 cm) of snow. [16] In early December, a winter storm results in 3 deaths and 400,000 power outages. [17] The year ends with a record breaking cold wave. Flint, Michigan set a monthly record low. [18]

The year started with an intense tornado outbreak that became the 2nd largest and 2nd deadliest for January. [19] The 81 tornadoes resulted in 20 deaths. [20] An EF3 tornado in Mississippi caused 4 deaths, 57 injuries and $9.46 million in damage. [21] [22] [23] The next day, an EF3 tornado in Georgia causes 11 deaths, 45 injuries and $2.5 million in damage. [24] [25] [26] Another EF3 tornado in Georgia caused 5 deaths, 40 injuries and $310 million in damage. [27] [28] [29] [30] [31] Total damage was $1.3 bilion in damages. [32] Two weeks later, an EF3 tornado strikes New Orleans, causing 33 injuries, including 5-6 serious. [33] It caused at least $2.7 million in damage. [34] [35] It was part of a small outbreak of 15 tornadoes that day. Total economic losses were estimated at $175 million. [36] Another intense outbreak occurs in late February and early March. This included an EF4 tornado in Missouri and Illinois, causing 1 death, 12 injuries and $14.8 million in damage. [37] [38] [39] [40] Another EF3 in Illinois and Indiana causes 1 death, 2 injuries and $5.7 million in damage. [41] [42] [43] As another tornado that day killed two in Illinois, the total death toll was four. [44] Total damage is $1.3 billion. [32] A week later, another tornado outbreak affected the Central United States. Nineteen people were injured, [45] [46] Damage totaled $2.5 billion. [32] More tornadoes affect the US on April 2 and 3. The 59 tornadoes from the system cause 3 deaths. [47] [48] Less than a week later, two die due to a tornado in Paraguay. [49] Another tornado outbreak affected the United States in late April and early May. The storm system resulted in $1.9 billion, [32] and caused 20 total deaths. Five of those deaths are tornadic. Two fatal tornadoes strike Canton, Texas which cause a combined 4 fatalities, 49 injuries and $1.87 million. [50] [51] [52] [53] A tornado outbreak sequence in mid to late May results in 2 deaths, 39 injuries and $975 million. [54] Significant tornadic activity slowed down after this. On August 6, a small outbreak of tornadoes occurred near Tulsa, Oklahoma. The tornadoes cause 30 injuries, all due to an EF2 in Tulsa, and $50.24 million, of which $50 million is due to the EF2 in Tulsa. [55] Five days later, more tornadoes occur in China. The tornadoes cause 5 deaths and 58 injuries. [56]
The first tropical cyclone of the year was a tropical disturbance in the South Pacific, which formed on January 2 over the Solomon Islands. It was the first of 20 tropical cyclones in the South Pacific during the year, [57] [58] including Cyclone Donna, which became the strongest cyclone on record in the basin in the month of May, with 10 minute sustained winds of 205 km/h (125 mph). [59] In the neighboring Australian basin, there were 28 tropical cyclones, most of them weak; [57] [58] however, Cyclone Ernie in April reached Category 5 intensity on the Australian tropical cyclone intensity scale, with 10 minute sustained winds of 220 km/h (140 mph). [60] Cyclone Debbie struck Queensland in March, causing A$3.5 billion (US$2.67 billion) in damage and 14 deaths across Australia. [61] [62] In November, Cyclone Cempaka killed 41 people in Indonesia from heavy rainfall. [63] The south-west Indian Ocean was quiet, with only six tropical cyclones during the year. [57] [58] Of these, Cyclone Dineo in February killed at least 258 people when it moved through Mozambique and Zimbabwe. [64] [65] Cyclone Enawo struck Madagascar in March, killing 78 people. [66] There was also a subtropical cyclone – Guará – which formed off Brazil in December. [67]
In the northern hemisphere, activity began on January 7, when a tropical depression formed and later moved across the Philippines, killing 11 people. [68] It was the first of 41 tropical cyclones in the western Pacific Ocean in the year. [69] The final two storms of the season – Kai-tak and Tembin – moved through the Philippines in December, together causing 406 deaths. [64] The year's costliest typhoon was Hato, which left more than US$4.34 billion in damage when it moved ashore southern China near Hong Kong. [70] In the north Indian Ocean, there were 10 tropical cyclones, which included several deadly storms. Cyclone Ockhi in December killed more than 137 people in Sri Lanka and southern India. [69] [71] There were 20 tropical cyclones in the eastern Pacific Ocean, including Tropical Storm Lidia, which killed 20 people when it struck western Mexico. [69] [72]
In the Atlantic Ocean, activity began in April and lasted until November, with 18 tropical cyclones, [69] including several deadly and costly storms. In August, Hurricane Harvey struck southeastern Texas and subsequently stalled over the state, dropping 60.58 in (1,539 mm) of rainfall; this was the highest amount of precipitation associated with a tropical cyclone in the United States. The rains caused widespread flooding along the storm's path, particularly near Houston, resulting in more than 100 fatalities and US$125 billion in damage, tying Harvey with Hurricane Katrina in 2005 as the costliest United States hurricane. [73] In September, Hurricane Irma struck the northern Lesser Antilles and later Cuba as a Category 5 hurricane, and later Florida at a lower intensity, causing more than US$50 billion in damage and 139 deaths. [74] Two weeks after Irma, Hurricane Maria struck Dominica as a Category 5 hurricane and later Puerto Rico as a Category 4 hurricane, causing US$90 billion in damage and more than 3,000 deaths, mostly in Puerto Rico. [75] [76] [77] Also during the season, Hurricane Nate produced damaging floods across Central America, killing 45 people. [78]
In addition to the above cyclones, there was a Mediterranean tropical-like cyclone called Cyclone Numa, which killed 22 people when it struck Greece. [79]

A satellite tornado is a tornado that revolves around a larger, primary tornado and interacts with the same mesocyclone. Satellite tornadoes occur apart from the primary tornado and are not considered subvortices; the primary tornado and satellite tornadoes are considered to be separate tornadoes. The cause of satellite tornadoes is not known. Such tornadoes are more often anticyclonic than are typical tornadoes and these pairs may be referred to as tornado couplets. Satellite tornadoes commonly occur in association with very powerful, large, and destructive tornadoes, indicative also of the strength and severity of the parent supercell thunderstorm.
The 2008 Atlanta tornado outbreak was a destructive and deadly tornado outbreak that affected the Southeastern United States on March 14–15, 2008. The most infamous tornado of the outbreak occurred on March 14 when an isolated but strong EF2 tornado caused widespread damage across Downtown Atlanta, Georgia, including to the CNN Center and to the Georgia Dome, which was hosting the 2008 SEC men's basketball tournament. Other buildings that were damaged include the Georgia World Congress Center, Philips Arena during an Atlanta Hawks game, and the Omni Hotel, which was evacuated after many windows were blown out. The Westin Peachtree Plaza Hotel suffered major window damage. The image of the building with all its windows blown out became famous and for a time was a symbol of the tornado. Centennial Olympic Park, SunTrust Plaza and historic Oakland Cemetery were also damaged.
From June 23 to 26, 2012, Tropical Storm Debby produced a significant tornado outbreak across the Florida Peninsula. Throughout the entire event, 25 tornadoes touched down across the state, making the outbreak the second largest on record in Florida, behind only that spawned by Hurricane Agnes, which produced 28 tornadoes from June 18 to 19, 1972. At least ten of the tornadoes—the largest 24-hour total in South Florida since Hurricane Isbell produced eight in 1964—had been confirmed in four South Florida counties by the National Weather Service forecast office in Miami.
On December 23, 2015, an outbreak of supercell thunderstorms produced tornadoes across northern Mississippi and middle Tennessee, resulting in 13 tornado-related deaths and numerous injuries. Other tornadoes occurred as far north as Indiana and Michigan. Scattered tornado activity continued over the next two days before the outbreak ended. This was the first of two deadly tornado outbreaks to impact the southern United States during December 2015 with the other occurring just a day after this one ended.
An unusually prolific and very destructive late-winter tornado outbreak resulted in significant damage and numerous casualties across the southern and eastern half of the United States between February 23–24, 2016. Lasting over a day and a half, the outbreak produced a total of 61 tornadoes across eleven states, which ranked it as one of the largest February tornado outbreaks in the United States on record, with only the 2008 Super Tuesday tornado outbreak having recorded more. In addition, it was also one of the largest winter tornado outbreaks overall as well. The most significant and intense tornadoes of the event were four EF3 tornadoes that struck southeastern Louisiana, Pensacola, Florida, Evergreen, Virginia, and Tappahannock, Virginia. Tornadoes were also reported in other places like Texas, Florida, and Pennsylvania. Severe thunderstorms, hail and gusty winds were also felt in the Northeastern United States and Mid-Atlantic states on February 24 as well.
This page documents notable tornadoes and tornado outbreaks worldwide in 2017. Strong and destructive tornadoes form most frequently in the United States, Brazil, 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 and Australia. Tornadic events are often accompanied with other forms of severe weather, including strong thunderstorms, strong winds, and hail.
A prolific and deadly winter tornado outbreak struck areas across the Southeast United States between January 21–23, 2017. Lasting just under two days, the outbreak produced a total of 81 tornadoes, cementing its status as the second-largest January tornado outbreak and the third-largest winter tornado outbreak since 1950. Furthermore, it was the largest outbreak on record in Georgia with 42 tornadoes confirmed in the state. The most significant tornadoes were three EF3 tornadoes that heavily damaged or destroyed portions of Hattiesburg, Mississippi, and Albany and Adel, Georgia. A total of 20 people were killed by tornadoes—mainly during the pre-dawn hours of the outbreak—making it the second-deadliest outbreak in January since 1950, behind the 1969 Hazlehurst, Mississippi tornado outbreak that killed 32 people. In addition, the tornado death toll was higher than the entire previous year. In the aftermath of the outbreak, relief organizations assisted in clean-up and aid distribution. Total economic losses from the event reached at least $1.3 billion.
A small but damaging outbreak of 15 tornadoes impacted the Southeastern United States on February 7, 2017. The most damaging tornado of the outbreak was a large and powerful EF3 tornado. The tornado caused considerable damage along its path and left approximately 10,000 homes without electricity. 33 injuries occurred in the area after the tornado hit near Chef Menteur Highway with hundreds of structures sustaining moderate to significant damage along the ten-mile path. In response to the disaster, Governor John Bel Edwards declared a state of emergency.
The tornado outbreak of February 28 – March 1, 2017 was a widespread and significant outbreak of tornadoes and severe weather that affected the Midwestern United States at the end of February 2017 and beginning of March. Fueled by the combination of ample instability, strong wind shear, and rich low-level moisture, the event led to 71 confirmed tornadoes and thousands of other non-tornadic severe weather reports. The most notable aspect of the outbreak was a long-tracked EF4 tornado—the first violent tornado of 2017 and the first violent tornado during the month of February since the 2013 Hattiesburg, Mississippi tornado—that tracked from Perryville, Missouri to near Christopher, Illinois, killing one person. Three EF3 tornadoes were recorded during the event, including one that caused two fatalities in Ottawa, Illinois, one that caused a fatality near Crossville, and one that heavily damaged or destroyed homes in and around Washburn. In addition to the deaths, 38 people were injured by tornadoes and an additional 30 were injured by non-tornadic impacts, mainly by fallen trees.

The following is a list of weather events that occurred on Earth in the year 2020.
As Hurricane Isaias moved up the East Coast of the United States, a damaging outbreak of 39 tornadoes impacted areas from South Carolina to Connecticut between August 3–4, 2020. The most significant tornado of the outbreak was a large and intense EF3 tornado that obliterated a mobile home park near Windsor, North Carolina, killing two and injuring 14. This was the strongest tornado in the United States to be spawned by a tropical cyclone since 2005. In the end, the outbreak killed two and injured 26.
This page documents notable tornadoes and tornado outbreaks worldwide in 2021. 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.
A significant tornado outbreak sequence took place from March 24–28, 2021 in the Southern United States, just one week after another outbreak affected similar regions. There were 43 tornadoes confirmed across 11 states, with the bulk of activity primarily on March 25, which resulted in the Storm Prediction Center (SPC) issuing its second high-risk outlook for the month of March, as well as the second high-risk outlook for 2021. Several intense tornadoes touched down on that day, including ones that prompted the issuance of rare tornado emergencies near Hoover, Alabama, Brent and Centreville, Alabama, and in the Newnan, Georgia area. March 27 also saw widespread tornado activity mainly across East Texas, Southern Arkansas, Louisiana, and Western Tennessee with several strong tornadoes touching down. Scattered to widespread wind and hail damage occurred throughout the outbreak sequence, and repeated rounds of heavy rain caused widespread severe flash and river flooding across much of Tennessee.
The following is a list of weather events that occurred in 2021. The year began with La Niña conditions. There were several natural disasters around the world from various types of weather, including blizzards, cold waves, droughts, heat waves, tornadoes, and tropical cyclones. In December, powerful Typhoon Rai moved through the southern Philippines, killing 410 people and becoming the deadliest single weather event of the year. The costliest event of the year, and the costliest natural disaster on record in the United States, was from a North American cold wave in February 2021, which caused $196.4 billion (USD) in damage; the freezing temperatures and widespread power outages in Texas killed hundreds of people. Another significant natural disaster was Hurricane Ida, which struck southeastern Louisiana and later flooded the Northeastern United States, resulting in $70 billion (USD) in damage. December saw two record-breaking tornado outbreaks, only four days apart from each other. In Europe, the European Severe Storms Laboratory documented 1,482 weather-related injuries and 568 weather-related fatalities. The National Oceanic and Atmospheric Administration documented 796 weather-related fatalities and at least 1,327 weather-related injuries in the United States and the territories of the United States.
Hurricane Ida generated a tornado outbreak as it traversed the Southeastern, Mid-Atlantic, and Northeastern United States. Thirty-five confirmed tornadoes touched down from Mississippi to Massachusetts; one person was killed in Upper Dublin Township, Pennsylvania, and several people were injured in Alabama, New Jersey, and Pennsylvania. The most active and destructive part of the outbreak occurred during the afternoon of September 1, when several strong tornadoes struck Maryland, New Jersey, and Pennsylvania, including an EF3 tornado which impacted Mullica Hill, New Jersey. The same storm later dropped an EF1 tornado that prompted a tornado emergency for Burlington, New Jersey and Croydon, and Bristol, Pennsylvania, the first of its kind in the Northeast, as well as the first such alert associated with a tropical cyclone or it's remnants. This outbreak severely impacted New Jersey and the Philadelphia Metropolitan Area, a region which had been significantly impacted by strong tornadoes from another outbreak that occurred just over a month prior, as well as several weak tornadoes from the remnants of Tropical Storm Fred two weeks earlier. Overall, the 36 tornadoes killed one person and injured seven others.
The following is a list of weather events that occurred on Earth in the year 2022. The year began with a La Niña. There were several natural disasters around the world from various types of weather, including blizzards, cold waves, droughts, heat waves, wildfires, floods, tornadoes, and tropical cyclones. The deadliest weather event of the year were the European heat waves, which killed over 26,000 people, 11,000 of which were in France. The costliest weather event of the year was Hurricane Ian, which caused at least $112.9 billion in damages in Florida and Cuba. Another significant weather event was the Pakistan floods, which killed 1,739 people and a total of $14.9 billion in damages.
