AMS Statements in Process

Statements Accepting Comments
AMS Statements that are being considered by the AMS Council for approval are posted on the AMS Web site at least at least thirty days before the Council vote. The Council may consider a statement either at one of the two regularly scheduled meetings each year, or at any time in between using e-mail discussion and electronic balloting. In addition, statement preparation does not follow a fixed schedule so statements may come up for consideration at any time of the year. AMS Members who are interested in providing input to statements are encouraged to check the AMS Web site regularly to see if any are under review at that time.

Update and Revision of the AMS Policy Statement Prediction and Mitigation of Flash Floods
The AMS Policy Statement on the Prediction and Mitigation of Flash Floods has recently expired. A subgroup within the AMS Hydrology Committee has determined that there should be revision to the AMS Statement. This is based on a number of factors, including increased monetary losses due to the occurrence of significant flash flooding, recent flash flood research and interest internationally with the problem, and growing concerns of both the increased frequency and intensity of extreme precipitation events under climate change scenarios as outlined by the Intergovernmental Panel on Climate Change (IPCC) and U.S. National Assessment. 

Looking at NOAA/NWS Hazard statistics, flash flood damages have averaged about $1 billion total property and crop losses per year and about 50 fatalities per year since 1996 in the U.S. The concern for flash floods has grown, as evidenced by the European Union’s development of the HYDRATE program, the objective of which “is to improve the scientific basis of flash flood forecasting by extending the understanding of past flash flood events, advancing and harmonizing a European-wide innovative flash flood observation strategy and developing a coherent set of technologies and tools for effective early warning systems.” Moreover, there has been increased emphasis internationally on the implementation of local flash flood forecasting systems.
