    Waves modelized by MFWAM on the global domain, forced by the Arpege 10 meters winds. 18 parameters are provided every 3 h : the significant height, the mean direction and the mean period for the 5 kinds of waves : total sea, wind waves, total swell, primary swell and secondary swell ; moreover, the peak period of the total sea, the 10 m wind direction and speed are available. For the 0h production, the forecasts are provided until 102h ; for the 6h production, the forecasts are provided until 72h ; for the 12h production, the forecasts are provided until 84h ; for the 18h production, the forecasts are provided until 60h.

    Analyzed parameters : name of the issuing centre (FMEE), date, storm identifier (name), position, current motion and intensity of the system, envelope of the cloud area associated with presence of frequent CB, CB tops maximum height (in flight level), the boundary of surface winds of at least gale force. Forecast parameters : positions and intensities (10-min average maximum winds) of the system at 06, 12, 18 and 24 hours lead times. Frequency and updating : graphical product issued as soon as a tropical system generating surface winds of at least gale force is present within the area of responsibility and disseminated every 6 hours, normally within one hour after the synoptic time (00, 06, 12, 18 utc). Production tool : Synergie.

    Storm surge modelized by Hycom2D on the NE Atlantic Ocean and the North Sea, forced by the Arpege 10 meters winds and atmospheric pressure on the sea. The model grid is curvilinear with an horizontal resolution of around 1 km on the french coasts. 3 parameters are provided : the instantaneous storm surge (delivered every hour), the maximal storm surge during the 3 previous hours (delivered every 3 h) and the maximal storm surge during the 24 previous hours (delivered every 24 h). For the 0h production, the forecasts are provided until 102h ; for the 6h production, the forecasts are provided until 72h ; for the 12h production, the forecasts are provided until 84h ; for the 18h production, the forecasts are provided until 60h.

    Waves modelized by WW3 on a unstructured grid, nested in the MFWAM grid, forced by the Arpege 10 meters winds. 13 parameters are provided every 3 h : the significant height, the mean direction and the peak period for the 4 kinds of waves : total sea, wind waves, primary swell and secondary swell ; moreover, the mean period of the total sea is available. For the 0h production, the forecasts are provided until 102h ; for the 6h production, the forecasts are provided until 72h ; for the 12h production, the forecasts are provided until 84h ; for the 18h production, the forecasts are provided until 60h. For all these 4 productions, a period of 6h analysis is also provided (WW3 forced by the Arpege analysis of the 10 m wind).
