Flood Forecasting System and Warning System (FloCAST)

A hydrological forecasting and early warning system designed to provide flood forecasts, inundation outlooks, and warning information to support preparedness, response, and risk reduction

Note: Focus on operational flood forecasting and early warning

Link To DSS: https://flood-ffwc.rimes.int/indexb.php

Developer: RIMES

Stage Of Maturity: Operational, Continuously evolving

Coverage: Regional (Asia-Pacific)

Climate Timescales Covered: Extended Range (Sub-seasonal), Real-time / Near Real-time Monitoring, Short-range (Weather: 0–10 days)

Strengths

Strong operational flood forecasting capability
Integrates meteorological and hydrological data
Provides actionable early warning information
Supports basin-level and local decision-making
Enables threshold-based alerts and preparedness actions
Can be customized for different river systems

Weaknesses

Accuracy depends on quality of input data (rainfall, river gauges)
Requires calibration for specific basins
Limited direct end-user interface (relies on national dissemination systems)
May require integration with impact models for full IBF capability
Technical capacity required for operation and maintenance

Synergies

Can use forecast inputs processed through FOCUS
Supported by data integration from RIMES Regional Data and Analytics System
Can feed into impact-based platforms like SMART and SATARK
Can complement risk context from UN ESCAP Risk and Resilience Portal
Can integrate with sectoral DSSs (e.g., agriculture, water management)
