The risk of slipping rises clearly with increased slipperiness.
The Finnish Meteorological Institute gives warnings about highly slippery pedestrian weather when extra attention should be paid to the choice of footwear and slip guards should be worn. There may be wide local variations in walkway conditions, depending on factors such as maintenance practices and the volume of traffic.
The warning specifies the cause and duration of slippery conditions. Between about seven and twenty warnings are issued each year per region.
Yellow is the colour used in the weather warnings for pedestrians.
