Narva, on Estonia’s eastern border with Russia along the Narva river, receives around 650 mm (about 26 inches) of rain a year, typical of the wider Baltic climate, with a summer peak from convective thunderstorms. The river, which forms the border and flows from Lake Peipus to the Gulf of Finland, has a generally moderate flow, leaving fast-developing local summer storms as the more immediate weather-related hazard for the city. Because Narva sits at Estonia’s far eastern edge, somewhat apart from the country’s main weather-monitoring hubs, radar tracking provides a genuinely useful independent check on local storms. Estonia’s Environment Agency operates the national radar network.
