A yellow weather warning for wind and snow is in place across the North of Ireland for today and Tuesday.
Heavy snow showers and icy surfaces are likely to lead to travel disruption, according to the Met Office.
This follows a yellow weather warning for wind and rain at the weekend due to Storm Ciara.
The latest warning forecasts gusts of up to 60 mph in exposed areas with snow as colder air moves in.
Several centimetres of snow will gather on hills, especially on higher ground above 150m (492ft). Lower levels may also see ice and snow showers, especially at night.
The warning, which came into force at midnight on Sunday, will continue until midnight on Tuesday and will mainly affect the north coast.
There is a further warning of snow and ice on Wednesday.
So far the Glenshane Pass, the main route from Derry to Belfast, is clear and moving well at the moment, say Traffic Watch NI.
Video footage shows wintry showers overhead on the road but traffic is moving freely despite the conditions.
If you are leaving from the City of Derry Airport today, you are advised to check your flight in case of any disruptions to arrivals or departures.
Meanwhile, the C602 Lisdivin Road in Strabane was closed last night due to flooding.
The road has now been reopened and passable with care.
