A severe weather system is set to batter the country over the next 72 hours, bringing intense storms, heavy rainfall, and sub-zero temperatures in several regions.

  • Severe storms and heavy rainfall expected between Wednesday and Thursday.
  • Risk of flooding in Buenos Aires, Córdoba, Santa Fe, and Entre Ríos.
  • Polar cold wave to bring temperatures as low as -5°C in southern regions.
  • Weather stabilization expected to begin from Friday, August 28.

The National Meteorological Service (SMN) has issued a high-alert warning for a massive weather shift across the country. Over the next 72 hours, a combination of extreme precipitation and a polar cold wave is expected to create challenging conditions for multiple provinces.

Storm Forecast and Intense Precipitation

According to meteorological data, instability will begin to escalate on Wednesday, August 26, with increasing cloud cover and scattered showers in parts of Buenos Aires. However, the peak of the storm is anticipated for Thursday, August 27, when intense thunderstorms, heavy rain, and potential hail are expected to strike. Regions such as Buenos Aires, Córdoba, Santa Fe, and Entre Ríos are under significant flood risk due to the projected volume of rainfall.

Why This Matters

BozokMedia analysis shows that such rapid transitions from thermal instability to heavy precipitation can overwhelm urban drainage systems and pose significant risks to agricultural sectors. The sudden onset of storms following a period of fluctuating temperatures complicates emergency response efforts.

Weather experts warn that the convergence of high humidity and sudden temperature drops will trigger severe convective activity.

The regional impact will vary significantly. While the northern parts of the province may see temperatures climb toward 20°C, the central regions like Tandil and Olavarría will struggle with freezing conditions, with temperatures dipping near -2°C accompanied by frost.

Polar Cold Wave and Sub-Zero Temperatures

Simultaneously, a polar cold wave is set to maintain its grip on several key sectors. The SMN has placed Santa Cruz, La Pampa, Santa Fe, Entre Ríos, and Corrientes under surveillance. In the southernmost reaches, temperatures could plummet to as low as -5°C, creating a harsh environment for residents.

Did You Know?: Rapidly moving storm fronts can cause sudden pressure drops, often leading to much higher wind gusts than initially predicted.
