Ostrava, in the northeastern Czech Republic close to the Polish border, receives around 700 mm (about 28 inches) of rain a year, more than Prague or Brno, reflecting its position closer to the Beskid mountains where terrain helps intensify rainfall. The region has experienced significant flooding in the past when heavy rain combined with the mountainous watershed sent rivers over their banks, including notable events in 1997 that affected much of the wider region. Faster, more localized summer thunderstorms remain a separate, more immediate hazard. Because the mountains create such distinct local weather patterns, radar offers a clearer picture than general regional forecasts. The Czech Hydrometeorological Institute operates the national radar network.
