Overview
- Heavy rains tied to a DANA and El Niño Costero have caused multiple huaicos that collapsed long stretches of the Panamericana Sur and the Costanera Sur, leaving hundreds to thousands of vehicles stranded and blocking key southern supply routes.
- Regional and national crews have opened provisional detours and deployed heavy equipment, but stranded passengers and transporters say assistance is inadequate and full road restoration could take days to weeks depending on weather and machinery availability.
- A frontal collision on the Puquio–Nasca road on Wednesday, August 19 between a Perseo interprovincial bus and a fuel trailer killed one person and injured about 20–21 others who were taken to hospitals in Nasca and Puquio while police investigate the cause.
- Separate incidents raised further casualties: a crane accident at Minera Las Bambas on August 19 killed two workers and injured three, and a tourist vehicle that fell about 80 meters on Cuesta de Lipán in Jujuy left two family members dead after the daughter later died in hospital; prosecutors have ordered peritajes in both cases.
- Authorities warn more huaicos are likely as SENAMHI links the extreme rains to a DANA named Aníbal interacting with El Niño Costero, a pattern that heightens the risk of repeated slope failures, wasted perishables, livestock losses and continued pressure on emergency services.
