During Monday morning, there were several accidents in Sörmland County and the rescue service warned of black ice.
SMHI has now issued a class 1 warning for slipperiness in Dalarna County, Värmland County and Gävleborg County.
The warning applies to a sudden ice slide on Tuesday morning.
- It is in connection with a rain area that comes in overnight.
It looks like it could be icy and you have to be especially careful early in the morning, says SVT's meteorologist Deana Bajic.
Mild and rainy
Later on Tuesday, it can also be slippery in Västernorrland.
- There is a risk of ice skating there later in the afternoon when the rain gets there.
But there is no warning for that yet.
On Monday, the sun has appeared over large parts of the country.
But according to the forecast, it will shine with its absence in the coming days.
- It will be rain and mild and up to ten plus degrees on Wednesday in the southern parts of the country.
Colder in the north
Further north, however, it will be colder and maybe even some snow.
- You can expect below ten degrees below zero.
On Wednesday evening and the night before Thursday, it can also snow in northern Norrland.
But on Thursday it looks like it will be sunny again.
- It will be clear and sunny in large parts of the country then, says Deana Bajic.
