Overview
- The Servicio Meteorológico Nacional said a cyclogenesis — rapid low‑pressure development that intensifies precipitation and winds — strengthened Thursday and is producing enhanced rain, thunderstorms and gusty winds across the Litoral and northeastern provinces.
- SMN maintained yellow rainfall alerts for Entre Ríos, Corrientes, Misiones and Santa Fe with expected accumulations of about 40 to 70 millimeters and the possibility of more intense, localized downpours or isolated storms.
- Separate yellow wind warnings cover coastal Río Negro and the Buenos Aires coast with gusts above 70 km/h and an additional Friday alert for Tierra del Fuego and the Falkland Islands forecasting southerly gusts that may exceed 90 km/h.
- The frontal system is followed by a marked cold‑air push that will drop temperatures over central and southern Argentina and raise the likelihood of weekend heladas in some provinces.
- SMN and local media are circulating public‑safety advice to secure loose objects, avoid travel where flooding or wind damage is likely, clear drains and disconnect appliances if water enters buildings, while forecasts for Galicia, Spain, show a contrasting dry and milder pattern per AEMET.
