How we forecast flooding

Scottish Flood Forecasting Service

This strategic partnership between the Scottish Environment Protection Agency (SEPA) and the Met Office combines hydrological and meteorological information for the first time, so that both organisations can share their expertise to improve the accuracy of flood forecasts for the whole of Scotland.

We collect data from our network of over 250 rainfall, river and coastal monitoring stations throughout Scotland generated 24 hours a day. This hydrological information is combined with meteorological information from the Met Office, which our team of experts use to predict the likelihood and timing of river, coastal and surface water flooding.

The Scottish Flood Forecasting Service produces a daily, national flood guidance statement issued to Category 1 and 2 agencies, such as emergency responders, local authorities and other organisations with flooding management duties. Each daily statement gives an assessment of the risk of flooding for the next five days and provides organisations with valuable time to put preparations in place to reduce the impact of flooding. 

Read our guide to learn more about how flood guidance statements are used to help manage the risks of flooding.

The service also directly helps those using SEPA’s Floodline service, by providing more specific information allowing SEPA to issue more timely flood warnings and give people a better chance of reducing the impact of flooding on their home or business.

Flood warning development framework

As flood warning authority under the Flood Risk Management (Scotland) Act 2009, and in undertaking our Civil Contingencies Act 2004 Category 1 duties, we aim to develop and improve our flood forecasting and warning service to reduce the impact of flooding on our most vulnerable communities. SEPA has developed a Flood Warning Development Framework, which covers the period 2017 to 2021 and explains how we intend to deliver and develop our service over the next five years.
