Trondheim, in central Norway, receives around 890 mm (about 35 inches) of rain a year, less than Bergen but still substantial, reflecting its fjord-side position exposed to Atlantic and North Sea weather systems moving in from the west. Rain is fairly evenly spread through the year, with autumn typically the wettest season. The Nidelva river running through the city has occasionally seen elevated levels during heavy rain, though the risk is generally more localized flash flooding than large-scale river flooding. Because coastal Norwegian weather can shift quickly, radar remains a useful everyday tool for the city’s outdoor-oriented population. Norway’s Meteorological Institute operates the national radar network.
