On 15 May 2022, an extratropical cyclone moved through the southern region of Brazil and stopped offshore. The low made a retrograde movement and obtained subtropical characteristics, according to Centro de Hydrografia da Marinha (the CHM). On the morning of 17 May, the cyclone transitioned into a subtropical storm, and was given the name Yakecan. [14] During its trajectory, the storm caused snow in the Gaúcha and Catarinense Mountains, setting record lows for this time of year. [15] The cyclone lost its subtropical characteristics and was downgraded late on 19 May to a low-pressure area. [16]

Preparations

Following confirmation of the formation of the storm on 16 May, preparations began for damage reduction and possible weather strategies.

Brazil

In addition to the preparations of each state, the national civil defence was watching the storm situation with concern, thus already providing a number for emergency information via mobile phone. [17]

Rio Grande do Sul

In Rio Grande do Sul, some municipalities cancelled classes in the municipal public education network, highlighting the municipalities of: Porto Alegre, Canoas, Gravataí, Alvorada, Glorinha, Cachoeirinha, Eldorado do Sul, Guaíba, São Jerônimo, São José do Norte, Santa Vitória do Palmar, Chuí, Capão do Leão, Jaguarão, Pedro Osório, Piratini, Pinheiro Machado and Turuçu. [18] Besides major universities in the state have confirmed changes to their timetables due to the storm, among them: Federal University of Rio Grande, Federal University of Health Sciences of Porto Alegre, Unisinos, Federal University of Pelotas, Federal University of Rio Grande do Sul, Centro Universitário Ritter dos Reis, Lutheran University of Brazil, Fundação do Ministério Público (FMP), Instituto Meridiona (IMED), Universidade Feevale and the Pontifical Catholic University of Rio Grande do Sul. [18]

The civil defence together with the water and electricity companies were in a state of readiness to respond to possible calls that have already been programmed due to the strength of the storm. [19] In Porto Alegre, the Municipal Secretariat of Social Assistance was on duty for possible accidents and assistance to homeless people, teams were approaching and referring homeless people to hostels, shelters and hostels. The city hall made available the Tesourinha Gymnasium as a reception base for the homeless population. [20]

Santa Catarina

In Santa Catarina, the civil defence expected a somewhat weaker storm after hitting the state of Rio Grande do Sul, the main concern was the cold wave that hit the region and could even cause snowfall. [21] Another concern was with the geographical location of Florianópolis, given that it is an island bathed directly by the sea, which could reach waves up to 5 metres (16 ft) high with winds of up to 99 km/h on the coast. [22]

Impact

Brazil

Rio Grande do Sul

More than 220,000 people were affected by power cuts in greater Porto Alegre and Campanha Gaúcha because of the cyclone. Several power poles and cables were broken, leaving residents in the dark. [23] On Lake Guaíba, the storm damaged a boat carrying three people, resulting in one of them drowning. [24]

Santa Catarina

Several municipalities of the coastal strip and mountainous sector of Santa Catarina registered wind damage. On the slopes of the Santa Catarina mountains, the wind was intense enough to cause vehicles to topple over. [25] Due to the intense cold, in the higher areas the cyclone's action caused winter precipitation between 17 and 18 May, in the form of snow and frozen rain; [25] prior to Yakecan, snow had not fallen in the state in 15 years. [26]

Paraná

In Paraná, the ports of Paranaguá and Antonina operated partially due to the intensity of the winds brought by subtropical cyclone Yakecan. [27] According to the Paraná System of Technology and Environmental Monitoring (Simepar), wind gusts were recorded with an intensity that exceeded 64 km/h (40 mph) on the coast of the state. In Guaratuba, a boat and a bridge that gave access to the floats sank on 18 May. [27]

Elsewhere

The presence of Yakecan caused a polar air mass to extend over much of southern Brazil on 18 and 19 May, causing several places to observe record-low temperatures. The city of São Paulo recorded a historic low of 6.6 °C (43.9 °F) on 18 May, while the Federal District recorded its lowest ever temperature of 1.8 °C (35.2 °F) on 19 May. In Belo Horizonte, Minas Gerais, the temperature fell to 4.4 °C (39.9 °F), the lowest it had been in 43 years. [26]

Uruguay

Storm surge caused by the cyclone flooded several streets in the departments of Maldonado, mainly in the city of Punta del Este [28] and Rocha, as well as other locations in Canelones and Lavalleja. Four people had to leave their homes after the house where they were staying collapsed in the gale. [29] Rescue teams were sent out to respond to 204 incidents across the country. In Rocha, first responders were deployed on 20 occasions to clear trees and fallen power lines. [30] In La Paloma, trees and roofs collapsed with the force of the wind blocking several streets in the department. The gusts reached close to 100 km/h (62 mph) and INUMET (Uruguay's National Meteorological Institute) declared an orange alert for the whole country. [31] [32] In the Uruguayan capital Montevideo, a 23-year-old man died after a tree collapsed onto his home. [24]

<span class="mw-page-title-main">South Atlantic tropical cyclone</span> Tropical cyclones in the South Atlantic Ocean

South Atlantic tropical cyclones are unusual weather events that occur in the Southern Hemisphere. 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 extremely rare, and Hurricane Catarina in 2004 is the only recorded South Atlantic hurricane in history. Storms can develop year-round in the South Atlantic, with activity peaking during the months from November through May. 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. Below is a list of notable South Atlantic tropical and subtropical cyclones.
