The cold front that swept central Argentina at the end of July 2024 triggered a series of yellow and orange storm alerts, heavy rain, strong winds, hail and isolated tornadoes across Buenos Aires Province, Santa Fe, Entre Ríos and neighboring regions. The initial event caused street flooding, power outages, airport disruptions and minor structural damage.

Two years later, a similar weather pattern re‑emerged in early August 2026. The Argentine Servicio Meteorológico Nacional (SMN) issued orange alerts for thunderstorms and strong winds across central and eastern provinces on 6 August, warning municipalities such as Mercedes, Suipacha, Luján, La Plata, Necochea and Quequén of gusts up to 90 km/h, rainfall of 30‑80 mm and a rapid temperature drop. Adjacent countries also faced severe weather: Uruguay declared orange alerts for ten departments, and Chile’s Maule region expected gusts of 60‑95 km/h with up to 70 mm of rain.

On 6 August, SMN reinforced orange alerts for Santa Fe and much of Buenos Aires province, forecasting 50‑80 mm of rain, intense lightning, hail and wind gusts exceeding 90 km/h, while a yellow alert remained for less‑intense storms elsewhere. A separate yellow alert warned of intense winds in Salta, with gusts up to 100 km/h. Authorities again urged residents to secure loose objects, avoid travel in heavy rain, stay away from trees and power lines, and follow official guidance.
