The Met Office has issued severe weather warnings for North Devon throughout Monday, January 21 and Tuesday, January 22.
Sub-zero overnight temperatures will lead to ice forming where snow has fallen or melted today.
The Met office warns there is also the risk of further localised snowfalls of up to 5cm in places during Monday.
As temperatures fall below freezing on Monday night into Tuesday morning icy stretches are likely on untreated surfaces especially in areas where any further sleet, snow or rain has fallen on Monday.
It is believed the conditions could cause travel disruptions across the south west.
