Argentina's National Meteorological Service (SMN) issued yellow alerts for storms on March 7, 2026, in Río Negro, San Luis, San Juan, Mendoza, and Neuquén, following a similar pattern seen in late February. An orange alert is active in Salta, indicating higher risk, with warnings for the coming hours.
This is the second instance in early 2026 of widespread SMN storm alerts, after yellow warnings on February 22 affected central and northern provinces.
Yellow alerts signal potentially damaging storms, including intense rain, gusty winds, and hail, while orange denotes greater severity. Affected areas in Río Negro, San Luis, San Juan, Mendoza, and Neuquén should prepare, per advisories issued around 3:00 a.m. on March 7. Salta remains under orange alert.
The SMN urges the public to monitor updates for specific zones and take precautions against severe weather.
