A “rare” phenomenon that will have the characteristics of an “extratropical cyclone” may affect the eastern coast of Buenos Aires starting this Sunday with “several days of rain and very intense winds” that will persist until at least Tuesday, reported the National Meteorological Service (SMN)
The agency detailed that there will be “intense winds and rains in the southeast and east of the province of Buenos Aires and then move northeast, away from the continent, which will cause winds from the southern sector with speeds between 45 and 55 kilometers per hour and gusts up to 75 kilometers per hour.
The SMN explained that “the Atlantic Coast and the Río de la Plata may be affected by the external part of the cyclone” and that next Tuesday “it is possible that this region will once again have very windy conditions, with gusts between 50 and 70 kilometers per hour”.

“It is very exceptional that a warm core system forms at these latitudes. These are typical characteristics of tropical systems, better known as hurricanes or tropical cyclones,” the SMN said.
The agency stressed that although this type of phenomenon “is not very frequent in our region”, it has been recorded on other occasions over the Atlantic Ocean, off the coast of the province of Buenos Aires, Uruguay and southern Brazil.
He specified that the last cyclone of these characteristics occurred towards the end of June 2021 and was called Raoni.
