Assimilation of this data is used to produce an initial state of a computer model of the atmosphere, from which an atmospheric model is used to forecast the weather. These forecasts are typically: medium-range forecasts, predicting the weather up to 15 days ahead; monthly forecasts, predicting the weather on a weekly basis 30 days ahead
The Po, Italy's longest river (652 kilometres or 405 miles), flows from the Alps on the western border with France and crosses the Po Valley on its way to the Adriatic Sea.

The difference between the forecast and the actual weather outcome for forecasts 3, 5, 7, and 10 days in advance. It was not until the 20th century that advances in the understanding of atmospheric physics led to the foundation of modern numerical weather prediction .
This was followed by drought in Italy in 226 BC, which lasted six months. In December of 170 BC there was a blood rain in Rome. Written sources from about 75 BC to c. 175 AD also emphasize moisture, mainly in the form of the Tiber floods in Rome. Large Tiber floods occurred in 5 (lasted seven days), 15, 36, 51, 69, 79 and 97 AD.
The European Flood Awareness System (EFAS) is the first operational European system monitoring and forecasting floods across Europe. It provides probabilistic, flood early warning information up to 10 days in advance to its partners – the National Hydrological Services and the European Response and Coordination Centre (ERCC).
