3. National capacity for flash flood forecasting and warning Flash flood forecasting and warning procedure 1. Forecast weather patterns for extensive rainfall based on the satellite, radar images and observations Radar image Observed rainfall Satellite image
3. National capacity for flash flood forecasting and warning 2. Analyze and forecast rainfall using the numerical weather models for different provinces and river basin catchments. 3. Overlap the observed and forecasted rainfall, land cover, hill s slope, river network and provincial maps to obtain the flash flood risk map.
5. National capacity for flash flood forecasting and warning Observed rainfall Forecasted rainfall Potential flashflood map 4. Analyze the forecasted rainfall pattern and potential flash flood map, then issue the flash flood forecasting and warning
3. National capacity for flash flood forecasting and warning The NCHMF has been applied the Flash Flood Guidance System (FFGS) software provided by the Mekong River Commission (MRC) for flash flood forecasting and warning in Vietnam since 2009
3. National capacity for flash flood forecasting and warning Flash flood and landslide risk map for 14 provinces in Northern Vietnam (based on hill s slope and land cover maps)
4. Collaboration with emergency management, governmental and nongovernmental agencies
