The inventive device comprises telecommunications transceiver interacting with a network for data exchange and a user interface interacting with the telecommunications transceiver for displaying information extracted from received data, wherein telecommunications transceiver is arranged for receiving meteorological data from which a display for the user interface is extracted. Telecommunications transceiver is connected for spontaneously interacting with a station for defining a geographic area and for accessing, in a substantially uniform manner, to a data set containing forecast pluvial/duration pairs which are valid for the geographic area for consecutive periods, the data set being dated by a time marker. The user interface is provided with a range of ordinate display segments, each of which is provided with several display states. The device also comprises a pilot for reacting to the reception of a data set by selectively updating the state of at least certain display segments according to the forecast pluvial/duration pair(s) contained in received data and to the relation between the time marker of the set and the temporal reference of the segments.
