Winter weather patterns in Peru and Chile continue to be characterized by rain, overcast skies, and varying regional conditions.

In Peru, the meteorological phenomenon ‘Dana Aníbal’ has intensified the impact of heavy rains, causing widespread flooding, landslides, and infrastructure damage. In the southern Caravelí province, mudslides and rockfalls have blocked the Panamericana Sur highway between kilometers 709 and 782, leaving hundreds of buses and heavy vehicles stranded. Similar landslides have affected coastal roads and activated ravines in Moquegua and Tacna.

In Tacna, residents in the Leoncio Prado neighborhood reported street flooding and sewage overflows following the collapse of a drainage manhole. In Lima, the district of Villa El Salvador experienced significant flooding due to intense rainfall and sewage system collapses; authorities reported extracting 115,000 gallons of water to restore transit, while local officials requested field hospitals to mitigate potential epidemiological risks.

As the crisis evolves, the Peruvian government plans to declare a state of emergency in the most affected districts and regions. In Lima Sur, districts including Villa El Salvador and Chorrillos have reported hundreds of affected residents, dozens of damaged homes, and several impacted schools. The flooding was exacerbated by sewage system collapses, prompting President Keiko Fujimori to announce a restructuring of the state water utility, Sedapal, to address structural failures. To support the agricultural sector facing El Niño-related risks, S/ 800 million will be allocated. In the south, transport remains paralyzed on the Panamericana Sur highway between Atico and Ocoña, and Tacna International Airport was temporarily closed as a precaution.

In Chile, weather conditions remain localized. Curicó and Pucón continue to face high probabilities of rain and cold temperatures, with Pucón recording lows of 2°C. Santiago and Viña del Mar have maintained drier, cloudy conditions.
