A yellow alert has been issued for multiple provinces in Argentina due to anticipated severe weather, including storms, rain, snow, strong winds, and the Zonda wind. The National Meteorological Service (SMN) warned that conditions could rapidly deteriorate across a wide swath of the country.

The alert encompasses Formosa, Chaco, Corrientes, Misiones, Santa Fe, Entre Ríos, La Rioja, San Juan, Mendoza, San Luis, Neuquén, Río Negro, and Chubut. The combination of factors poses a significant risk to residents and travelers in these areas.

These storms are expected to bring heavy rainfall in short periods, accompanied by lightning and possible hail. Wind gusts could reach up to 80 km/h (approximately 50 mph).

Accumulated rainfall totals are estimated between 40 and 70 mm (approximately 1.6 to 2.8 inches), with the possibility of higher amounts in certain locations.

Rainfall and Snow Alerts

The rainfall alert indicates that some areas will experience localized heavy downpours, with accumulated precipitation between 10 and 30 mm (approximately 0.4 to 1.2 inches). Rain and snow are also possible at higher elevations.

Snowfall is expected in some areas, with accumulations potentially reaching between 10 and 20 cm (approximately 4 to 8 inches).

Strong Winds and Zonda Winds

Strong winds are forecast for mountainous areas, with speeds between 50 and 70 km/h (approximately 31 to 43 mph) and gusts potentially reaching 100 km/h (approximately 62 mph). Eastern Mendoza and San Luis are expected to experience southerly winds between 30 and 50 km/h (approximately 19 to 31 mph) with gusts up to 70 km/h (approximately 43 mph).

A Zonda wind alert is also in effect, with winds between 30 and 45 km/h (approximately 19 to 28 mph) and gusts up to 65 km/h (approximately 40 mph). The Zonda wind can cause reduced visibility, a sudden increase in temperatures, and remarkably dry conditions.
