  We analyze distributions of rain-event sizes, rain-event durations, and
dry-spell durations for data obtained from a network of 20 rain gauges
scattered in a region of the NW Mediterranean coast. While power-law
distributions model the dry-spell durations with a common exponent 1.50 +-
0.05, density analysis is inconclusive for event sizes and event durations, due
to finite size effects. However, we present alternative evidence of the
existence of scale invariance in these distributions by means of different data
collapses of the distributions. These results are in agreement with the
expectations from the Self-Organized Criticality paradigm, and demonstrate that
scaling properties of rain events and dry spells can also be observed for
medium resolution rain data.
