Remarks of a specialist

On Thursday, increased runoff and rising water levels are expected in rivers and streams, increasing the risk of flooding and landslides. This could cause damage and travel disruption in Southeast Iceland, the southern Eastfjords and the central highlands. Drainage systems in these areas may also come under increased pressure.

Due to malfunction we have turned off the service publishing hydrological data on the map. Instead see the data using our Rauntímavöktunarkerfi.
