WMO updating guidelines on impact-based forecasting, incorporating humanitarian input

The World Meteorological Organization says it will later this year issue updated guidance on impact-based forecasting, based on recommendations from a conference that included the IFRC.

The 2015 WMO Guidelines on Multi-Hazard Impact-Based Forecast and Warning Services were “based on the premise that it is no longer enough to provide a good forecast or warning of what the weather will be,” a WMO news story said earlier this month.

“People need information on what the weather might do, and how to ensure their safety and protect their property.”

The 2020 update will embrace “strong collaboration with partner agencies and significant research into exposure and vulnerability.”

Six new chapters will include advice on organizing impact-based information, the communication of risk “to ensure warnings are understood and acted upon”, and training that includes the “integration of community and traditional knowledge”, among other issues.

The new guidance was generated by a December symposium hosted by the UK Met Office that gathered participants from over 20 national meteorological and hydrological services, as well as UN agencies, the World Bank and the IFRC.

The WMO Friday said Cyclone Amphan (pictured) had “highlighted the value of multi-hazard early warnings” and praised the meteorological services of both India and Bangladesh. Accurate forecasts on the storm, the WMO said, had “underpinned a successful disaster mobilization campaign, including the evacuation of more than 3 million people.” (Photo: Indian Red Cross)
