Basics such as bread and milk are being distributed to residents by air while a number of PSNI and Red Cross 4x4s are distributing packages to homes where there is vehicular access.

A huge number of agencies are now involved in attempts to get the region back on its feet - NI's emergency services and mountain rescue teams are just some of those involved.

Aerial shots taken from UTV's helicopter show Co Antrim farms and roads blanketed in snow as disruption to work and travel continues.

PSNI Chief Superintendent Chris Noble said: "All the agencies are working closely together to ensure those affected by the continuing hazardous weather conditions have essential supplies such as food and medicine.

"We are all working hard to get the supplies to those in areas where vehicular access is difficult. Some of these people have now been snowed in for four days and it is vital we ensure they have adequate food and medical supplies," the District Commander said.

"While there has been an improvement in conditions in many areas, there are still hazardous conditions in a number of areas."

Chief Supt Noble appealed for motorists to only travel if absolutely necessary.

In some areas, heavy snow drifts left roads impassable, and many motorists were forced to abandon their cars.

A Met Office yellow warning for ice is in place until Tuesday morning.

"I would also appeal to walkers to be mindful of the dangers of snow covered hills and mountains. Do not place yourself in unnecessary danger," the senior police officer added.
