As of late October 2026, the ‘Super Niño’ phenomenon continues to drive extreme weather risks across Latin America, with an 83% probability of intense activity lasting through the first quarter of 2027. In Argentina, the Litoral region remains a primary focus for flood mitigation. The Argentine Navy has launched a large-scale humanitarian operation, deploying vessels like the ARA Ciudad de Zárate and ARA Punta Mogotes to provide medical and logistical support to riverine communities in Corrientes and other provinces. The Ministry of Defense has also mobilized the Army for ‘Operation Biguá’—a tactical training exercise involving 1,000 personnel to ensure readiness for flooding in provinces such as Misiones, Chaco, and Santa Fe. In response to the escalating threat, the National Parks Administration (APN) has launched the ‘ENOS 2026-2027 Work Plan’ across 18 protected areas in the Northeast, Northwest, and Central regions. Operating under the Federal ENOS Coordination Plan, this initiative focuses on identifying high-risk zones and strengthening meteorological and satellite information systems in provinces including Misiones, Corrientes, Chaco, Formosa, Entre Ríos, Santa Fe, Buenos Aires, Salta, and Jujuy. Public health and sanitation measures are also being intensified. In the Gran Resistencia area of Chaco, the provincial government is conducting spatial fumigation using ultra-low volume (ULV) machinery ~~in zones such as Canal Soberanía and Puerto Vilelas~~ to mitigate environmental risks. In San Juan, municipal teams are performing disinsectation and urban sanitation in neighborhoods like Villa Mallea Sur and Barrio Norte to prevent pest proliferation. Additionally, Corrientes authorities are providing essential services and social assistance to families affected by rising river levels. New coordination efforts have emerged in Mar del Plata, Argentina, where a Unified Emergency Center has begun operations to integrate Civil Defense, rescue services, and lifeguards, enabling the mobilization of over 1,000 specialized workers.
