Plzeň, in western Bohemia, receives around 480 mm (about 19 inches) of rain a year, among the drier parts of the Czech Republic, with a modest summer peak from convective storms. The city’s position at the confluence of several smaller rivers means it has experienced localized flooding during periods of sustained heavy rain, though generally less severe than events seen in Prague further downstream. Short summer storms remain the more routine hazard, occasionally bringing hail that affects the region’s agricultural land. Because Plzeň’s driest months leave drainage systems relatively unused, the first serious summer storms can cause disproportionate localized flooding. The Czech Hydrometeorological Institute operates the national radar network.
