Join us on March 17 at 1pm PT / 4pm ET (March 18 at 9am NZDT) for a deep dive into how one of the world's most complex coastal cities uses advanced hydrological forecasting to protect its communities and infrastructure.

Following record-breaking floods in 2023, Auckland Council sought proactive tools to gain crucial insights ahead of  storms and heavy rain events.

In this session, Kolt Johnson (Auckland Council) and Hunter Johnson (Upstream Tech) will discuss the practical application of AI-powered, probabilistic forecasting in a high-stakes municipal environment. Learn how Auckland Council leverages actionable forecasts to drive hydrological advice that supports real-time decision making and coordinated responses across multiple departments.

We’ll cover key insights from Auckland Council's journey, including:

  • Operationalizing emergency response: How Auckland Council integrates real-time, probabilistic forecasts into their emergency command center to drive faster, safer decisions during extreme weather.
  • Cross-departmental collaboration: How Auckland uses tailored forecasting insights to streamline communication with internal stakeholders, such as stormwater engineers and emergency responders.
  • Multi-use case efficiency: A look at how forecasting data supports diverse needs—from high-stakes emergency action planning to optimizing routine hydrological field operations.
  • Building long-term resilience: Auckland’s vision for the full hydrological cycle—applying forecasting insights to both immediate flood response and future drought resilience.
  • The innovation ecosystem: How Auckland Council layers HydroForecast with other cutting-edge technology to create a comprehensive picture of city-wide risk.
