A map display device, comprising: a map display control unit configured to bring up a map on display at a display monitor; a stormy weather condition information reception unit configured to receive stormy weather condition information, a stormy weather condition information display control unit configured to provide a storm path forecast, indicating a predicted path of a storm, based upon the stormy weather condition information by superimposing the storm path forecast over the map on display at the display monitor, said map display device being characterised by a predicted position selection unit configured to select a first predicted position and a second prediction position among a plurality of predicted positions that the storm is estimated to assume, wherein: the predicted position selection unit is further configured to select, as the second predicted position, a predicted position corresponding to a latest time point among the plurality of predicted positions and to select, as the first predicted position, a predicted position closest to a halfway point between the current position of the storm and the second predicted position; and the stormy weather condition information display control unit is further configured to display the storm path forecast by using two fan-shaped ranges, one centered on the current position of the storm with an arc (31, 41, 91) thereof passing through the first predicted position and another centered on the first predicted position with an arc (31, 41, 91) thereof passing through the second predicted position. a map display control unit configured to bring up a map on display at a display monitor; a stormy weather condition information reception unit configured to receive stormy weather condition information, a stormy weather condition information display control unit configured to provide a storm path forecast, indicating a predicted path of a storm, based upon the stormy weather condition information by superimposing the storm path forecast over the map on display at the display monitor, said map display device being characterised by a predicted position selection unit configured to select a first predicted position and a second prediction position among a plurality of predicted positions that the storm is estimated to assume, wherein: the predicted position selection unit is further configured to select, as the second predicted position, a predicted position corresponding to a latest time point among the plurality of predicted positions and to select, as the first predicted position, a predicted position closest to a halfway point between the current position of the storm and the second predicted position; and the stormy weather condition information display control unit is further configured to display the storm path forecast by using two fan-shaped ranges, one centered on the current position of the storm with an arc (31, 41, 91) thereof passing through the first predicted position and another centered on the first predicted position with an arc (31, 41, 91) thereof passing through the second predicted position. the predicted position selection unit is further configured to select, as the second predicted position, a predicted position corresponding to a latest time point among the plurality of predicted positions and to select, as the first predicted position, a predicted position closest to a halfway point between the current position of the storm and the second predicted position; and the stormy weather condition information display control unit is further configured to display the storm path forecast by using two fan-shaped ranges, one centered on the current position of the storm with an arc (31, 41, 91) thereof passing through the first predicted position and another centered on the first predicted position with an arc (31, 41, 91) thereof passing through the second predicted position.
