                         Cloud Cluster) technique using satellite and radar data. ForTraCC 
                         is an algorithm for tracking and forecast the physical 
                         characteristic of mesoscale convective systems (MCSs) through its 
                         whole life cycle using the thermal channel information (10.8 
                         {\`{\i}}m) of geostationary satellites or reflectivity (20 dBZ) 
                         from CAPPI radar data. The cloud cluster detection method is based 
                         on a threshold temperature or reflectivity; the morphological and 
                         radiative parameters of each MCS are evaluated and tracking trough 
                         the life cycle based on overlapping areas of MCSs in successive 
                         images. The forecast is built taking into account the life cycle 
                         history of each MCS, generating a virtual image for the next 120 
                         minutes. The extrapolation is based on the possible displacement 
                         of MCS (considering the position of the center of mass of the 
                         cloud cluster in previous time steps) and its size evolution. The 
                         use of this technique using radar data allow to obtain new 
                         parameters for nowcasting. This part of the study combined the 
                         volume scan from S band radar, operating during the RACCI/LBA, 
                         with the ForTraCC algorithm. The ForTraCC output allows following 
                         the rain cells during the life cycle. Rain cells were roughly 
                         defined as the 20 dBz threshold. This procedure produced 2500 life 
                         cycles to be analyzed. The preliminary results show the importance 
                         of the cloud top rate as a tool for nowcasting of the intensity of 
                         the convective cells in the next 30 minutes and allow describing 
                         the characteristics of the reflectivity profiles of the rain cells 
                         evolution during the life cycle. The ForTraCC technique using GOES 
                         12 data is an operational tool available on line in the 
                         following.",
