Sažetak
The whole area of Mount Medvednica and the surrounding lowland including the zagreb city area experienced extensive rainfall on 3 to 4 July 1989 causing flash floods. Daily precipitation amounts measured at 0600 UTC on 4 July were in proportion to the mean monthly totals of july for this region. The maximum rainfall amounts for periods of 2 to 12 hours recorded during this storm, had a return period greater than one hundred years in this region. They were produced by a mesoscale convective system along the slowly moving frontal zone lying over north-western Croatia. The interaction between mesoscale processes and the synoptic scale development led to the intensive transformation of the initial air masses at the frontal lineinto those with a much stronger convective potential.
