From Friday evening and during the night to Saturday, heavy rain showers will move in over Dalarna, Örebro, Västmanland, Gävleborg, Jämtland and Västernorrland.
According to SMHI, the rain showers can cause large amounts of water in a short time, which can cause local flooding problems.
In connection with the rain, it can also be windy with strong gusts of wind.
– The rain area has already started to move and will quickly intensify with large local variations, says Meteorologist Peter Kondrup.
The Swedish Transport Administration is already warning of a flooded section of the E4 north of Stockholm, between Rotebro and Bredden in the direction of Uppsala.
