Short summary

48 flash flood events in the urban Attica region (2005-2014) resulted in 3,500 fire service operations, mostly in autumn. Events were mostly associated with max accumulated rain over 20mm/24h and 3mm/10min. Impact intensity was particularly high for more than 60mm/24h. Rain intensity thresholds for flood triggering are produced for 15 sub-areas of the Attica region. The quality of the produced thresholds depends on the distribution and density of the rain gauges that cover each sub-area.
