Overview
- Provincial authorities increased planning and resources on Wednesday, August 26, 2026, with Buenos Aires creating a Mesa Interministerial and Mendoza reporting reinforced dikes, dredging and expanded monitoring systems.
- Peru's Cenepred released scenario maps showing more than 9 million people at very high risk from floods, river overflows, landslides and drought in different regions.
- Officials warned the event could be exceptionally strong based on global model guidance from the OMM and NOAA, so governments are treating late 2026 into early 2027 as the critical window for impacts.
- Preparedness steps include new meteorological stations and pluviómetros, mobile health patrols and field hospitals, large machinery contracts for channel and canal maintenance, and community guidance on drains, sandbags and waste removal.
- The response seeks to shield vulnerable groups and services such as schools and farms, with regional education officials saying about 205,000 students in Lambayeque could lose in-person classes if intense rains damage high-risk school buildings.
