Early warnings save lives and livelihoods yet many developing countries still lack adequate early warning systems.

Ensuring early warnings is essential to help people prepare for extremes. This is why in March 2022, UN Secretary-General António Guterres called for new action to ensure every person on Earth is protected by early warning systems within five years.

To guide global efforts under this initiative, we must have a solid understanding of where we are – to chart our path forward and hold ourselves accountable.

The Global Status of Multi-Hazard Early Warning Systems 2023 report outlines the progress that has been made under the Early Warnings for All (EW4All) initiative. It seeks to highlight good practices through case studies and examples of both global and regional initiatives which are contributing to the achievement of the goal set by the UN Secretary-General.

1. Making good progress…

The trend of increasing numbers of countries reporting the existence of multi-hazard early warning systems (MHEWS) has continued – the number has doubled since 2015 and increased to 101 countries as of March 2023.

  • Dramatic improvement has been witnessed in Africa and in the Asia and Pacific region.
  • Two-thirds of WMO members report having fully operational warning and alerting services and more than half incorporate hazard, exposure and vulnerability information in their warning products.
  • Advances in science and technology, together with the increase in available observations have led to improvements in forecasts, especially lead times.
