Remarks of a specialist

In the coming days, water levels are expected to rise in rivers and streams in most parts of the country due to precipitation and warmer temperatures. There is still a considerable amount of snow in the mountains, and it is expected to melt. Travellers should exercise caution near riverbeds and fords.

Due to malfunction we have turned off the service publishing hydrological data on the map. Instead see the data using our Real-time monitoring system.
