The National Meteorological Service (SMN) issued this February 28 a new yellow alert for high temperatures in a wide area of the central zone of the country, which includes the City of Buenos Aires, the Buenos Aires suburbsand 10 provinces.
According to the agency, it is a temperature level that can be dangerous to health, especially for risk groups such as children and people over 65, in some cases with chronic diseases.
The yellow alert, which implies “mild or moderate risk” for health according to the SMN, extends to the most of the province of Buenos Aires, Corrientes and Córdoba; southeast of Santiago del Estero, south of San Luis, north of La Pampa, and northwest of Neuquén.
As indicated by the SMN on its Twitter account, a new period begins with very high temperatures that will mainly affect the center of the country and the coast. This Monday, the pampas city of Santa Rosa is the hottest with 40°C.
On the other hand, it is pointed out that until the weekend minimums of between 22 and 25 degrees are expected, and maximums of between 33 and 28 in the region comprised by the provinces “Santa Fe, Entre Ríos, sectors of Córdoba, Corrientes, Santiago del Estero, Buenos Aires, La Pampa, San Luis, Mendoza and Neuquén”.
This Tuesday, the temperature had exceeded 36 degrees in the city of Buenos Aires, with a minimum of 21, with somewhat cloudy skies and winds rotating from the northwest to the northeast. According to the SMN, similar conditions are expected at least until Sunday, March 5, with higher minimums and increasing cloudiness from that date.
“There is a high pressure system over the Atlantic Ocean that favors a circulation from the north. So warm air is continually arriving throughout the region and that favors temperatures rising,” said Cindy Fernández, SMN meteorologist.
“Today the temperatures are at their peak and they will remain even until the weekend,” added the specialist. and estimated that “we could have a new heat wave in several provinces and, at the country level, it would be the ninth of the 2022-2023 season.”
For a heat wave to be determined, at least three consecutive days must be recorded with maximum and minimum temperatures above the threshold values for each location.
“This is the first time that there have been so many heat waves. When you look at the data backwards, there are usually no more than 4 or 5 heat waves per summer. And this year we have already doubled the number,” Fernández remarked. “It is expected that as climate change intensifies, summer after summer we will have more heat waves,” he anticipated.
