Webinar: Nowcasting for Urban Flash Flood Forecasting

Urban areas are increasingly vulnerable to flash floods due to rapid urbanization, climate variability, and inadequate drainage systems. These floods often develop within very short timeframes, leaving limited time for preparedness and response. 

Nowcasting, which focuses on short-term (usually 0-6 hours ahead) weather forecasting using high-resolution Numerical Weather Prediction (NWP) and real-time observations from remote sensing and in-situ stations, has emerged as a critical tool for improving monitoring and early warning services for urban flash floods. Advances in hydraulic and hydrological modelling in the urban context have significantly enhanced inundation prediction capabilities, which is important analysis of potential socio-economic impacts. 

Recognizing the ongoing developments of nowcasting-related products and their application in many countries, this webinar organized under the framework of the Associated Programme on Flood Management (APFM) aims to bring together experts, practitioners, and stakeholders to share knowledge, tools, best practices and challenges in nowcasting for urban flood risk management. 

The webinar aims to: 

• Provide an overview of recent advances in nowcasting techniques relevant to urban flash floods 
• Showcase operational applications and case studies from different countries/regions 
• Discuss integration of meteorological and hydrological data for real-time forecasting Identify challenges, gaps, and opportunities for improving urban flood early warning systems 
• Foster collaboration among stakeholders under the APFM framework

The Webinar agenda will be available soon.
