Prague sits on the Vltava river in a relatively dry pocket of central Europe, averaging around 500 mm (about 20 inches) of rain a year, with a summer peak from convective thunderstorms typical of the region. The Vltava has flooded the historic city center dramatically in the past, most notably during catastrophic flooding in 2002 when much of the lower city and its famous riverside districts were inundated for days, prompting major flood-defense investment since. Faster, more localized summer storms are a separate, more routine hazard capable of flash flooding on specific streets. Because both flood risks matter here but unfold so differently, radar is most useful for tracking the faster local storms. The Czech Hydrometeorological Institute operates the national radar network.
