Overview
- Chileese authorities reported on July 19 that the storm complex has killed four people, left one person missing and produced 1,652 damnificados with more than 1,500 people sheltered and thousands isolated by road cuts and landslides.
- The Dirección Meteorológica described a "train of frontal systems" with an intense atmospheric river, a concentrated plume of moisture that delivers heavy rain and extreme winds that have knocked out power to hundreds of thousands of homes and damaged hundreds of houses.
- The government extended emergency declarations to ten regions and moved an Army modular hospital to Ovalle to support Coquimbo, where locals say whole rural areas remain cut off and municipal leaders are seeking a catastrophe declaration to fund reconstruction.
- High‑mountain impacts have shut international corridors: Mendoza authorities carried out mass rescues of people trapped in deep snow and said the Cristo Redentor/Los Libertadores crossing is likely to stay closed through the end of the month because of heavy snow and route damage.
- A separate but simultaneous Zonda wind episode struck Jujuy, Argentina with gusts above 130 km/h that sparked fires, toppled trees and power poles, left thousands without electricity and forced provincial emergency operations to prioritize water and hospital backup power.
