Early Warnings for All











WMO 2025 Calendar Competition

Mr. Su Shuge (China)










The Early Warnings for All (EW4All) initiative aims to ensure universal protection from hazardous hydrometeorological, climatological and related environmental events through life-saving multi-hazard early warning systems, anticipatory action and resilience efforts by the end of 2027, as called for by the United Nations Secretary-General António Guterres in 2022.  











Global Status of Multi-Hazard Early Warning Systems 2025

Explore the latest findings on global progress toward universal early warning coverage — highlighting key achievements, remaining gaps, and priorities for action by 2027.


Read the 2025 Report










With human-induced climate change leading to more extreme weather and climate conditions, the need for effective multi-hazard early warning systems is more crucial than ever. Systems that warn people of impending storms, floods or droughts and support action are not a luxury but cost-effective tools that save lives, reduce economic losses, and provide a nearly tenfold return on investment. 

Early warning systems have already helped decrease the number of deaths and have reduced losses and damages resulting from hazardous weather, water or climate events. But major gaps still exist, especially in small island developing states and least-developed countries:



















55%

As of 2024, 108 countries report having some capacity for multi-hazard early warning systems, more than double the 52 countries in 2015.

Vulnerable Nations Progress

The least developed countries have shown the most significant improvements, with landlocked developing countries and small island developing states also surpassing the global rate.

+39%

The global average score for the comprehensiveness of multi-hazard early warning systems has risen from 0.35 to 0.49, an increase of 39%.

The four pillars of Early Warnings for All 

The Early Warnings for All initiative is built on four pillars to support countries in building and operating effective and inclusive multi-hazard early warning systems: 

Disaster risk knowledge - led by the United Nations Office for Disaster Risk Reduction (UNDRR) 

Detection, observation, monitoring, analysis, and forecasting - led by the World Meteorological Organization (WMO) 

Warning dissemination and communication - led by the International Telecommunication Union (ITU)

Preparedness and response capabilities - led by the International Federation of Red Cross and Red Crescent Societies (IFRC)












Disaster Risk Knowledge (UNDRR)


Collecting data and undertaking risk assessments to increase knowledge on hazards and vulnerabilities and trends










Detection, observation, monitoring, analysis and forecasting (WMO)


Developing hazard monitoring and early warning services
















Warning dissemination and communication (ITU)


Communicating risk information to all those who need it










Preparedness and response capabilities (IFRC)


Building national and community response capabilities

Pillar Leads


























Early Warnings for All is a groundbreaking initiative to ensure that everyone on Earth is protected from hazardous weather, water, or climate events through life-saving early warning systems by the end of 2027.
