Urban floods are flashy and can cause widespread damage due to the high concentration of population and development. Among mitigation strategies commonly used urban environments are: regulatory floodplain mapping, flood warning monitoring and notifications systems, and structural controls through capital improvement projects (CIP). Advanced storm forecasting, early flood detection, and timely communication of flood threat prior and during storm events are example ways in which a flood warning system can help reduce flood risk in urban communities. This topical session encourages cross-disciplinary collaboration between atmospheric scientists and urban hydrologists to discuss their experiences in the following areas:

• Flood and rain forecasting in urban watersheds
• Flood detection and measurement techniques
• Design storms due to changing rainfall intensities
• Vulnerability assessment of drainage assets
• Real-time emergency notification and response
• Regional approaches to flood monitoring and forecasting
• Coastal flooding of urban areas
• Lessons learned from past flooding
