The names are used sequentially without regard to year and are taken from five lists of names that were prepared by the ESCAP/WMO Typhoon Committee, after each of the 14 members submitted 10 names in 1998. ESTIMATED POSITIONS 22S038W AT 270000 UTC AND 24S039W AT 271200 UTC.  PAGASA also retires the names of significant tropical cyclones when they have caused at least ₱1 billion in damage or have caused at least 300 deaths. There have been over 82 recorded tropical and subtropical cyclones in the South Atlantic Ocean since 1957.  During early afternoon of March 13, the Brazilian Navy declared that Cari became a remnant low.  Significant tropical cyclones have their names retired from the lists and a replacement name selected at the next World Meteorological Organization Hurricane Committee. , A subtropical depression formed southwest of Rio de Janeiro on November 15, 2016. The storm caused fourteen deaths and the evacuation of thousands, with an emergency declared in four cities.  A study was subsequently performed and published during 2012, which concluded that there had been 63 subtropical cyclones in the Southern Atlantic between 1957 and 2007.  The name "Kurumí" replaced "Kamby" in 2018 without being used.  The name of a tropical cyclone is determined by using Lists A — D in order, without regard to the year before restarting with List A.  If a tropical cyclone causes loss of life or significant damage and disruption to the way of life of a community, then the name assigned to that cyclone is retired from the list of names for the region.  However, the system did not intensify any further, as it soon encountered unfavorable conditions, and Jaguar eventually dissipated on May 22. Subtropical Storm Alberto formed in May 2018. A subtropical storm is similar to a tropical storm in that it develops over the open ocean waters and, like a tropical storm, it has winds of at least 39 mph. Afterward, the storm began to weaken due to strong wind shear.  Within the Southern Hemisphere, systems must be characterized by a significant amount of gale-force winds occurring around the center before they are named. However, variations in the averaging period of winds in different basins make inter-comparison difficult. It has some characteristics of a tropical storm, but not all of them. A subtropical storm is a hybrid system.

A tropical system will …  Names are generally assigned in order from predetermined lists, once they produce one, three, or ten-minute sustained wind speeds of more than 65 km/h (40 mph). , Any member of the World Meteorological Organization's hurricane, typhoon and tropical cyclone committees can request that the name of a tropical cyclone be retired or withdrawn from the various tropical cyclone naming lists. VALID UNTIL 271200 UTC.  On early December 11, as it moved more southwardly, Guará attained its peak intensity while transitioning to an extratropical cyclone. Subtropical cyclones originate over tropical or subtropical waters and have a closed circulation about a well-defined center.  Hurricane Catarina was the third system, while the fourth system had a well-defined eye like structure, and formed off the coast of Brazil on March 15, 2004. Later that day, the system strengthened into a subtropical storm, receiving the name Jaguar from the Brazilian Navy Hydrographic Center. Most of Since 2011, the Brazilian Navy Hydrographic Center has assigned names to tropical and subtropical systems in the western side of the basin, near the eastern coast of Brazil, when they have sustained wind speeds of at least 65 km/h (40 mph), the generally accepted minimum sustained wind speed for a disturbance to be designated as a tropical storm in the North Atlantic basin. On March 16, Arani began experiencing 25 kn (13 m/s; 46 km/h; 29 mph) of wind shear because another frontal system bumped it from behind.  Two subtropical depressions formed in 2014: one in late-February 2014 and the other in late-March 2014. This depression has since strengthened into a subtropical storm and has been assigned the name Mani The National Hurricane Center defined a subtropical storm as: “A subtropical cyclone in which the maximum sustained surface wind speed (using the U.S. 1-minute average) is 34 kt (39 mph or 63 km/hr) or more.” A subtropical cyclone as defined by the National Hurricane Center is: The credit for the first usage of personal names for weather systems is generally given to the Queensland Government Meteorologist Clement Wragge, who named systems between 1887 and 1907. On March 27, Iba weakened into a tropical depression and turned to the east, before dissipating on March 28. The first one lasted until Christmas Day, 2013.  A name is retired or withdrawn if a consensus or majority of members agree that the system has acquired a special notoriety, such as causing a large number of deaths and amounts of damage, impact, or for other special reasons. ", National Oceanic and Atmospheric Administration, II. ", "Frequently Asked Questions: How do tropical cyclones form? , Two subtropical cyclones affected both Uruguay and Rio Grande do Sul state in Brazil between 2009 and 2010.  Should a cyclonic storm move into the basin from the Western Pacific then it will keep its original name. Strong wind shear, which disrupts the formation of cyclones, as well as a lack of weather disturbances favorable for development in the South Atlantic Ocean make any strong tropical system not usual,but the climate change make easier strong storms.  The Indonesian Badan Meteorologi, Klimatologi, dan Geofisika names systems that develop between the Equator and 10°S and 90°E and 141°E, while Papua New Guinea's National Weather Service names systems that develop between the Equator and 10°S and 141°E and 160°E. A low pressure area formed over the Congo Basin on April 9. The last subtropical storm in the Atlantic was Fay on Oct. 10, 2014.  The names are taken from four different lists of 25 names and are assigned when a system moves into or develops into a tropical depression within PAGASA's jurisdiction. , Iba was the first tropical storm to develop in the basin since Anita in 2010, as well as the first fully tropical system to be named from the Brazilian naming list.. Now named, although this was a SD earlier.  If all of the names on a list for a season are used, any additional tropical or subtropical storms are named after the letters of the Greek alphabet. 99.0k.  Formal naming schemes have subsequently been introduced for the North Atlantic, Eastern, Central, Western and Southern Pacific basins as well as the Australian region and Indian Ocean.  On March 29, a north-westerly flow encroached on the systems environment, which caused the system to rapidly move towards 40S and the cold waters that were present to the south of 40°S. , When a tropical depression intensifies into a tropical storm to the north of the Equator between 140°W and 180°, it is named by the CPHC. , Within the Eastern Pacific Ocean, there are two warning centers that assign names to tropical cyclones on behalf of the World Meteorological Organization when they are judged to have intensified into a tropical storm with winds of at least 34 kn (39 mph; 63 km/h). On January 21, 2020, the Brazilian Navy Hydrographic Center began to monitor an area of persisting thunderstorms near São Paulo for potential subtropical cyclone development.  A fourth one formed in late January 2015. The National Hurricane Center also began monitoring the system as Low SL90. Weather Underground provides tracking maps, 5-day forecasts, computer models, satellite imagery and detailed storm statistics for tracking and forecasting Tropical Storm Mario Tracker. A subtropical storm exhibits features of both tropical and non-tropical systems.  It lasted until February 1, when the cyclone became extratropical. , Early on March 14, 2011, the Navy Hydrographic Center-Brazilian Navy (SMM), in coordination with the National Institute of Meteorology, were monitoring an organizing area of convection near the southeast coast of Brazil. In comparison to tropical cyclones, the maximum winds occur relatively far from the center (greater than 60 nautical miles) and have a less symmetric wind field and distribution of convection.  Names are assigned in sequence from list A, while list B details names that will replace names on list A that are retired or removed for other reasons. Tropical cyclones and subtropical cyclones are named by various warning centers to simplify communication between forecasters and the general public regarding forecasts, watches, and warnings. A subtropical storm exhibits features of both tropical and non-tropical systems. South Atlantic storms have developed year-round, with activity peaking during the months from November through Ma… 21. Winds are often used to measure intensity as they commonly cause notable impacts over large areas, and most popular tropical cyclone scales are organized around sustained wind speeds. South Atlantic tropical cyclones are unusual weather events that occur in the Southern Hemisphere. , Within the Australian region in the Southern Hemisphere between 90°E – 160°E, a tropical cyclone is named when observations or Dvorak intensity analysis indicate that a system has gale force or stronger winds near the center which are forecast to continue. According to the Weather Prediction Center, places along Alberto's path received anywhere from 3-9 inches of rainfall and the system traveled so far north it impacted many areas in the Midwest.  If all of the names on a list are used, storms are named using the letters of the Greek alphabet. The weather station owned by MetSul Weather Center in Morro Redondo, Southern Brazil, recorded 278.2 mm (10.95 in) in a 24-hour period.  On March 12, the Brazilian Hydrographic Center downgraded Cari to a subtropical depression, while the CPTEC stated that the storm had become a "Hybrid cyclone". The next day it moved offshore northern Angola with a curved cloud pattern.  Should the list of names for a given year be exhausted, names are taken from an auxiliary list, the first ten of which are published every year.  However, if the system should weaken into a deep depression and subsequently reintensify after moving into the region then will be assigned a new name.
