The Krka in central Slovenia has been spilling over, as have the Ljubljanica, Poljanska Sora, Savinja and a dozen smaller rivers across the central part of the country.

The flooding is starting to affect traffic.

There are several road closures on the main road along the Sava around Zidani Most in central Slovenia, along the Dravinja in the east and on many sections of local roads in the east.
