Genoa cyclone approached to Croatia on November 5th which shifted to the southeast on next day along with cold front. The heaviest rainfall occurred on 6th November in Gorski Kotar, the northern Adriatic and in the western parts of the inland. In only 24 hours locally fell average monthly rainfall amounts. The highest amount of precipitation was recorded on Platak meteorological station, which recorded 250 mm of precipitation in 24 hours. Several other meteorological stations recorded more than 100 mm of rainfall in 24 hour period. Therefore, there were torrents and water streams spills in Istia and in coastal region of Kvarner Bay. On 7th November, weather shortly calmed down. Then in the evening on the 10th over Croatia moved another cold front, and from 11th November new cyclone came from the western Mediterranean. During that events Croatian Meteorological and Hydrological Service (DHMZ) issued warnings for public that included both meteorological and hydrological warnings. Warnings for National Protection and Rescue Protectorate (NPRD) include flood possibilities and water levels prediction for several rivers in Primorsko-goranska region, Ličkosenjska region and Karlovačka region. Luckily, there were no human casualties. Hydro warnings were based on the results of Mike11 – hydrological and hydrodynamic model, European Flood Awareness System (EFAS) and Southeast Europe Flash Flood Guidance System (SEEFFGS). The paper will present two case studies for events over the same region that happened within an interval of a few days based on meteorological and hydrological analyses
