The Swedish Meteorological and Hydrological Institute (SMHI) has issued a class-1 weather warning for hard winds and driving snow for the Swedish Mountains. Wind speeds of 20 metres-per-second are expected tomorrow. The islands of Gotland and Öland will also be hit.
The stormy weather will die down on Thursday before picking up again over the weekend, with snow in central and northern parts.
