FLASH flood forecast and warning service

FLASH is an easy-to-use flood forecasting service for all levels of government, emergency responders, and private entities. It allows you to monitor, forecast and alert flooding to enable communities to become flood resilient, protect assets and save lives.

Fast, accurate, and reliable 

Urbanisation and climate change are combining to increase the number of people, assets, communities, and businesses at risk from catastrophic flash floods. To build resilience, government and private organisations need faster, more accurate early warning systems that can give a greater lead time before an extreme flooding event.

That is why we developed FLASH. It’s a cloud-based tool that lets you access flood information in real-time, from anywhere, and alert others of potential danger up to 12 hours in advance. 

Proven in Australia’s Parramatta River Catchment – where it provides the country’s fastest and most accurate flood forecasts – FLASH gives you reliable results in minutes when other models take hours. As a result, you have more time to take effective action and informed decisions when it comes to orders to evacuate and road closures.

And because it is available on a simple subscription basis, using existing models and delivered through the cloud, you can implement FLASH quickly and effectively.

The benefits of the FLASH service

Accurate flood warnings in minutes
Rapid hydrodynamic modelling can turn rainfall predictions into street-level flood warnings within minutes, giving you more time to act.
Sophisticated modelling with reliable data
FLASH combines real-time rainfall data from government sources with sophisticated weather prediction algorithms and modelling to give unparalleled forecast reliability.
Access from any device, anywhere
Thanks to its cloud-based delivery, FLASH lets you access flood information and send alerts from anywhere you have internet access.
Simple annual subscription
Get started with FLASH quickly and easily using your existing models into a serviceable FLASH flood warning system.
API connection to your own systems
All data is stored on the cloud, using Lizard database portal, and is fully accessible through API and a web portal – so you can easily connect it to your own geoplatform or business intelligence tools.

User-friendly dashboard

FLASH provides a user-friendly dashboard which presents the data in a very clear and visual way. For the administrators of the system, FLASH provides an intuitive interface.

What makes FLASH so fast and accurate?

Accurate flood warnings begin with reliable rainfall and water level data. FLASH uses real-time data from official sources including Australia’s Bureau of Meteorology, as well as radar based forecasting and a Numerical Weather Prediction (NWP) algorithm, applying a sophisticated climate model.

The resulting information feeds a rapid, 2D hydrodynamic flood model such as TUFLOW. This produces extremely fast flood forecast results, which can create flood maps at a street level with accurate flood depths within minutes after intense rainfall is forecast.

Lizard, an integrated cloud based system lets you use the data however suites you best - you can access its web portal from anywhere or use its API to connect business information or GIS tools. Its user-friendly dashboard includes rainfall and water level gauges, with interactive real-time and predicted flood maps.

Through the portal you can select locations that trigger a notification when a predefined water level is exceeded and create a customised warning for parts of the catchment. Being Cloud based software, the dashboard is accessible from anywhere that your Cloud enabled device has an internet signal.
