Heavy rains intensified around February 19–20, causing flash floods and debris flows in multiple districts

The Chullo torrentera (ravine) overflowed prominently, dumping thick mud, rocks, and water into neighborhoods on February 19

A second, more intense wave hit on February 22, just days after initial cleanup, worsening damage in areas like Yanahuara, Cayma, Cerro Colorado, Sachaca, and others

Streets turned into fast-moving rivers of mud, burying vehicles, destroying roads, and threatening homes. Some reports noted over 16 districts affected in the initial wave, with widespread infrastructure impacts. Many were displaced

Peru declared a state of emergency in over 700 districts (nearly half the country) across regions including Arequipa, Ica, Piura, Tumbes, and others. This allowed faster access to funds for repairs, relief, and recovery.
