A local weather radar (LWR) has been developed by modifying X-band marine radar. LWR has been installed and operated to measure presipitation in Bandung area, West Java, Indonesia at 107.586491' W and6.894958° S. During its observation, LWR has detected hail falling in West Bandung region on March 26, 2016. LWR. can observe hail formation and growthprocesses thanks to its 2 minutes of sampling interval. Hail occurence was also confirmed by C-band weather radar installed 120 km away in northwest side of LWR site and black body temperature data of Himawari 8 satellite which analyzed using Auer method. This C-band radar identify hail occurence at 2.43 pm until 3.14 pm (around 31 minutes). Maximum recorded reflectivity data of this hail precipitation is 58.46 dBZ which close to 55.1 dBZ of C-band radar data. This results confirm that LWR is suitable as a low cost solution for disaster early warning system due to precipitation.
