Guidelines on the Implementation of a Coastal Flood Forecasting and Early Warning System (2022 Edition) – Global



WMO publishes guidelines on coastal flood early warning systems

The new WMO guidelines on the implementation of an early warning system for coastal flood forecasting offer sound and practical advice to countries, donors and experts who wish to set up warning systems early against increasing risk.

The guidelines are a contribution to the United Nations’ Early Warnings for All initiative and reflect the high priority needs of small island developing states (SIDS) and least developed countries that are particularly vulnerable to these coastal hazards.

“The severity of disaster impacts, especially on coastal communities, is well known and documented. A contributing factor is the increasing intensity and frequency of meteorological and oceanographic hazards caused by climate change, including sea level rise, which can seriously affect SIDS and other coastal nations,” the guidelines state. .

“It is essential to recognize that coastal flooding can result from one or more hazards, and is exacerbated by the impacts of climate change, particularly associated with sea level rise.”

“Coastal flooding events pose an increasing threat to the lives and livelihoods of people living in low-lying and populated coastal areas. In addition, the issues for most countries that have vulnerable coasts are the increasing level of fisheries, tourism and infrastructure development, as well as the sustainability of their communities,” he says.

The new guidelines were presented at a side event at the WMO Commission on Weather, Climate, Water and Related Environmental Services and Applications (SERCOM), attended by over 140 participants from around the world. whole, including the South Pacific, the Caribbean and Africa. .

WMO is grateful to the Climate Risk and Early Warning Systems Initiative and the Korea Meteorological Administration for their financial support.

These guidelines are based on the successful implementation of demonstration systems in four countries between 2009 and 2019 as part of the Coastal Flood Forecasting Demonstration Project, which included a particular focus on the Pacific Islands. They also incorporate the key principles of WMO’s Flash Flood Guidance System (FFGS) and Severe Weather Forecasting Programme.

The aim is to be a one stop shop that countries can follow to prepare and implement their own coastal flood forecasting early warning system. It provides a simple 10-step process with templates outlining policy, management and technical processes that countries or regions can use to create their own early warning system, from vision to implementation. As this information is not always readily available in many countries, these guidelines have focused on these characteristics when developing and building a system, including information needed for sponsors and guidance on resources needed to to succeed.

The Guidelines are also a registered activity of the United Nations Decade of Ocean Science for Sustainable Development.
