"Already this morning we've had an additional 3cm of snow this morning with 7cm of level snow with drifts some 15cm.
"The heavy snow showers will continue with blizzard conditions at times and severe drifting of snow as the day goes on as winds pick up to gust 35-40mph later.
"A further 5-10cm of powder snow expected.
"The core of the cold is over us so it will be dangerously cold for the elderly to be out & if you become trapped in your car with wind chills around -12c.
