Met Éireann has issued a nationwide Yellow weather alert for low temperatures and ice. 

The alert will remain in place until Monday morning at 11am. 

Temperatures will drop as low as minus three degrees overnight. 

A fog warning is also in place until tomorrow at 12pm. Met Éireann has warned the frog will be freezing in some parts of the country and be most dense overnight. 

Met Éireann has warned of slippery conditions, hazardous travelling risks and animal welfare issues overnight. 

Dublin Fire Brigade has warned road users to drive slowly, increase braking distances and use high gears when possible. 

Some showers of hail and sleet are also expected along with the ice, and it may fall as snow on higher ground. 

There will be some isolated showers, mainly along northern and northeastern coasts, with patchy rain lingering for a time in southeastern counties.

Meteorologist Alan O’Reilly said it will be a “bitterly cold” weekend, but it will clear up by Tuesday. 

He also said the ice and low temperatures don't mean snow is a given.

“It's very far out to talk about a white Christmas,” he said. 

“It does look like we’re going to stay in unsettled and milder conditions to the end of the week, but beyond that we really don’t know.” 

Intense snowy conditions have also put the German city of Munich in a near-lockdown. Videos show houses and cars completely covered in snow, while today’s soccer match between Bayern Munich and Union Berlin was cancelled due to “snow weather chaos”. 

Flights have also been delayed in Munich until at least 6am tomorrow. 

Met Éireann meteorologist Aoife Kealy previously told Newstalk Breakfast it will be bright but chilly.
