  3. Ministerio del Ambiente PERÚ Servicio Nacional de Meteorología e Hidrología - SENAMHI INTRODUCTION 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.

  4. ANALYSIS OF THE RAINFALL EPISODE The city of Cusco is located at south-eastern zone of Peru, StudyArea Near Cusco is Vilcanota/Urubamba River valley. located about 10 miles north of Cusco Peru, and extends northwest through Pisac and Ollantaytambo cities.

  19. During January 2010 heavy rainfall and flooding across the Cusco region caused deaths, injured people, destroyed farms, bridges, railroads, producing economic losses around US $250 million. • We observe incress activity of South Atlantic convergence zone that persisted for several days and brought unusually large levels of moisture to the South Peru. • Data of Sea Surface Temperature suggest that increased warming of south Atlantic Ocean could be related to the increased activity of intertropical converge zone and therefore the strong rainfall event in Cusco region. • At this moment there are a project supported by national government to deploy 12 automatic weather station in that place to monitoring the weather in that region. CONCLUSIONS

  20. To establish an Early Warning System is neccesary in Cusco region, to warning the population by natural disaster. • To strengthen the capacity of local civil defense teams and organizations is necesary. • To organize the population is requerid to improve the emergency management. • Disaster Risk Management Specialists is necesary in order to manage the emergency and prevent future risks. RECOMMENDATIONS
