As of right now, Peru has called for a state of emergency in many cities. They have not been able to prevent this tragedy, but they have set up camps near the capital Lima since there has been damage in most areas. The government in Peru is trying their best to make repairs to some institutions, lets just hope this heavy rainfall and flooding sends soon.
