The Met Office have issued an amber weather warning for eastern parts of Northern Ireland saying periods of heavy snow are expected to cause 'disruption to travel and impacts on infrastructure'.
The warning comes on top of a yellow weather warning previously issued covering all of the province as the weekend approaches.
The amber warning comes into effect from 3pm today, Thursday 9 March, until tomorrow at 4pm.
A Met Office spokesperson said:
"Periods of snow are expected to develop for much of Northern Ireland into early afternoon, becoming heavy and persistent across the warning area.
"Strong easterly winds will accompany the snow, leading to atrocious travel conditions, especially, but not exclusively over higher ground. 4-8 cm of snow is likely away from immediate coasts, with 10-20 cm possible over higher ground. Significantly deeper snow drifts are possible.
"Snow should begin to ease by the early hours of Friday, before clearing to the east. Temperatures will fall quickly under clearing skies, leading to the risk of icy conditions developing."
