Rain warnings#
The rain warnings product cross-references rainfall forecast values with IDF (Intensity-Duration-Frequency) tables to provide forecasts in terms of return period.
These warnings are useful for generating alerts on vulnerable elements that are affected by drainage capacity exceedance problems.
Calculation#
The algorithm used for the calculation has been developed by the Centre de Recerca Aplicada en Hidrometeorologia (CRAHI) of the Universitat Politècnica de Catalunya (UPC).

SMC Radar - Rain warnings#
Warnings generated using the radar network of the Servei Meteorològic de Catalunya (SMC).
Temporal resolution#
The last 6 hours of observed data and 2 hours of forecasted data can be explored, with a time step of 6 minutes.
The units are return periods (years).
