Weather forecasts for Paraguay initially indicated a period of temperature fluctuations with clear skies and no immediate rain. However, conditions were expected to shift toward rain and electrical storms by late in the week.

This weather pattern escalated into a significant cold front moving in from the southwest. Starting Monday, September 21, authorities warned of intense rainfall with accumulations between 10 and 70 mm. Severe wind gusts of 70 to 90 km/h were anticipated, with potential hurricane-force gusts exceeding 100 km/h in northern regions and a risk of localized hail. The system was projected to impact southern departments—including Ñeembucú, Misiones, Itapúa, Caazapá, Paraguarí, and Guairá—before spreading to regions such as Alto Paraná, Caaguazú, and Concepción. In Asunción, temperatures were expected to drop to approximately 19 °C.

By early October, the weather pattern shifted toward rising temperatures and increased atmospheric instability. Following a humid and foggy period, temperatures were forecast to rise, reaching highs of 31 °C in Asunción and up to 35 °C in the Chaco region. The Dirección de Meteorología e Hidrología (DMH) predicted scattered showers and occasional electrical storms in locations including Villarrica, Coronel Oviedo, and Ciudad del Este, with instability expected to persist.
