An extreme precipitation event that affected almost all south highland of Peru is investigated. This event caused very strong socioeconomic impacts in the Cusco region.
The outstanding event of 22–24 January 2010 was connected to a strong south-esterly flow, probably caused by a intensity of South Atlantic convergence zone that persisted for several days and brought unusually large levels of moisture to the South Peru.
