The International Workshop on Flash Flood Forecasting, coordinated by the U.S. National Oceanic and Atmospheric Administration's National Weather Service and the World Meteorological Organization, provides information on the types of flash flood prediction capabilities available for application in flash flood prone regions in developing countries. A range of solutions; from simple inexpensive tools and applications to more sophisticated centralized forecasting systems are covered. Participants determined the "weak links" in establishing end-to-end operational flash flood warning systems and how to fill these gaps. Additionally, the Workshop identifies steps that can be taken to promote proven science and technology to developing countries.

The workshop consists of presentations by leading experts in operational meteorology, hydrometeorology, hydrology, satellite and radar precipitation estimation, geographic information systems (GIS) and the emergency management profession. They focus on how to deliver adequate lead-time and accuracy in forecasts to produce life and property saving actions to mitigate flash flood losses.

The workshop showcases case studies of successful end-to-end warning and response systems and effective flash flood forecasting operations. Small workgroups determine the weak links in establishing flash flood warning systems and propose solutions. Project briefs for establishing or improving flash flood forecasting services are presented. Finally, the workshop includes a dialogue with donor organizations. Vendor exhibitions complement the expert presentations.

All presentations are in Powerpoint. The other downloads are in PDF format.
