A YELLOW weather warning for snow and ice has been issued for the region.
The warning, by the Met Office, is in force from between 12pm Tuesday, January 29 and 11am on January, Wednesday 30.
The warning affects the Conwy region, Denbighshire, Bangor and Anglesey.
In a statement, the Met Office said: "A band of rain will arrive across Wales, Northern and Western England through the middle of Tuesday, then move eastwards through Tuesday afternoon and evening.
"The rain will turn quickly to snow on hills, then also to low levels in places.
"Three to five cms of snow is likely above 200 metres, with up to 10cm in a few places.
"A patchy covering of 1 to 2cm is possible at low levels, although some places will see no snow at all. As skies clear overnight, ice is likely to form on some surfaces. In addition, wintry showers will follow into western areas on Wednesday morning, giving further slight accumulations of snow in a few places."
