Likelihood that the flood depth exceeds a threshold, computed by matching every ensemble member to a library of 200 pre-simulated pluvial flood scenarios of its commune (RainyDay storms over the island hydrodynamic models, 30 m). Every commune of the country has its own library; the map shows the communes of the selected island side by side.

The dashed rectangle is the extent of the island mosaic; dashed lines are the commune boundaries (click a commune to select it). White dots are the impacts reported for the event in the SIDS Flash Flood Compendium. The basemap needs a connection; the likelihood layers work offline.
