Overview
- Meteorologists say a persistent atmospheric block is keeping a frontal zone nearly stationary over northern Argentina, which favors repeated rainfall across multiple regions.
- Storm activity is concentrated in the northeast, with Misiones, Formosa and northern Corrientes expected to see the heaviest and most frequent storms.
- The Servicio Meteorológico Nacional forecasts a high chance of strong rain in the Buenos Aires metro area, with probabilities reported at about 70% in the morning and 40% in the afternoon and temperatures near 10–15°C.
- Precipitation in Río Negro and Neuquén will be more scattered over the weekend but models indicate renewed rain early next week, and localized snow is possible in high Andean sectors of Mendoza, San Juan and the northwestern cordillera.
- The blocking pattern is limiting the advance of Pacific fronts, so instability could last several more days; short-term SMN updates are the authoritative source for warnings and local impacts such as urban flooding or travel disruption.
