These Standard Operating Procedures (SOPs) are intended to help catalyse and guide earlier humanitarian and development action to future ENSO-related extreme weather events (including drought, flooding, cyclones and extreme heat/cold and related events such as disease outbreaks). The SOPs outline what actions need to be taken, by whom and by when, once there are warning signs of a possible or impending ENSO event, to mitigate or prevent its impacts. They outline development and humanitarian actions for the international system.
