Yellow alert for storms for Mendoza and San Luis
Two yellow level alerts for storms, some locally strong, were issued this Saturday for
the east of the province of Mendoza and the west of San Luis
where accumulated precipitation of 30 to 45 millimeters and occasional hail was expected, according to the SMN. .
The agency reported that the storm alert was in effect for the Mendoza towns east of General Alvear, low areas of San Rafael and Malargüe, east of Las Heras, La Paz, Lavalle, San Martín and Santa Rosa.
The same alert applied to the east of the province of San Luis, in cities such as San Luis, low areas of Belgrano and Juan Martín de Pueyrredón.
"These areas will be affected by storms, some locally strong, it was reported, which "may be accompanied by intense gusts, occasional hail, strong electrical activity and mainly by abundant falls of water in short periods," the agency indicated.
Lastly, the SMN predicted accumulated precipitation values between 30 and 45 millimeters, which could be exceeded occasionally.
The “extraordinary data” left by the first heat wave
The first heat wave of the 2024 season is already behind us.
But its impact left "extraordinary data" in the records of the Meteorological Service.
What made it so notable?
The event stood out for its exceptional duration.
There were
23 consecutive days
of intense heat, from January 21 to February 12.
"But that's not all. Its geographical scope was astonishing
: it affected all the provinces
at some point during that period," they describe from the SMN, in a thread published in X.
So, this heat wave was
"extreme" and "extensive"
, two adjectives that separate it from the typical, usual, heat waves of each summer.
But, once again, why was it different?
"The strange thing is to have had a heat wave at the end of January during a strong phenomenon like El Niño," SMN meteorologist José Luis Stella had explained to Clarín.

The oppressive temperatures - which in the City and the GBA, for example, exceeded °39 - sustained and recorded in a large part of the national territory, took place because, precisely, the El Niño signal (the effect of its presence, such as intense rains) was inhibited by the
atmospheric blockage (anticyclone) in the Atlantic
, which prevented the passage of a cold front that could replace the mass of warm, almost tropical air.
"Not even Patagonia was spared. All regions felt the heat. 80 meteorological stations recorded a heat wave," the organization adds.
As the days passed, the heat intensified and spread throughout the Argentine territory.
But the wave had
two peaks of impact
: between January 31 and February 3, and from February 5 to 7.
The report revealed that during those peaks, more than 55 weather stations across the country detected the heat wave simultaneously.
Within this extended period, several locations surpassed their record for highest daily maximum temperature, some for January and others for February.
From 37° to 43.8°.
The record was taken by San Martín, in Mendoza
, which endured the heat wave for 12 days in a row.
The maximum in that department was 41.3°.
In the City, on February 6 the thermal exceeded 40 degrees in another oppressive day within the series.
At 2 p.m. that day
it climbed to 42.8°.
