Why early warning

Lives and assets can be saved when people are warned of approaching extreme weather

The earlier the heads up, the more time for people to take life-saving action.

  • 24 hours’ notice of an impending hazard can reduce damage and loss by 30%  
  • Nearly 6x less people killed by disasters in countries with substantial or comprehensive multi-hazard early warning than those where it’s limited  
  • Almost 5x fewer people affected by disasters where countries have strong multi-hazard early warning coverage 

Without early warning systems or services, the poorest and most vulnerable people are left especially exposed by the climate crisis.  

  • 60% of people in Africa unprotected by early warning systems 
  • 1 person killed by a natural hazard every 13 minutes in Asia  
  • $22.5 billion of direct damages from weather and climate hazards in the Caribbean 

Failsafe early warning  

What is needed to protect people from different types of weather hazards? 

Multi-hazard early warning effectively protecting people requires 4 cornerstones.

Disaster risk knowledge 

Systematic data collection for analysis, forecasting, and understanding of potential hazards and their risk

Detection, observation, monitoring and forecasting 

Constant monitoring of hazards for early warning systems and services  

Warning dissemination and communication 

Everyone at risk is warned, understands the danger, and knows what to do 

Preparedness and response 

Updated plans and resources at community to national level for timely action
