Flash floods are among the world’s deadliest natural disasters with more than 5,000 lives lost annually and result in significant social, economic and environmental impacts. Accounting for approximately 85% of the flooding cases, flash floods also have the highest mortality rate (defined as the number of deaths per number of people affected) among different classes of flooding (e.g., riverine, coastal).

Recognizing that flash floods have a particularly disastrous impact on lives and properties of the affected populations, WMO is implementing the Flash Flood Guidance System (FFGS) project in cooperation with with the Hydrologic Research Centre (HRC), based in San Diego, USA. The project supports the development and implementation of regional flash flood guidance and early warning systems to mitigate the impacts of flash floods and build the capacities of the National Meteorological and Hydrological Services (NMHSs) of the participating countries.
