As the Storm Emma collides with Beast from the East the Chairman of the National Emergency Co-ordination Group has warned the time for messing is over and urged people to comply with the stay indoors ordere.
Due to the risk to safety posed by the storm Mr Sean Horgan told RTÉ Radio 1 that people should be indoors. The advisory came into force at 4pm on Thursday. He said people should be at home but if they cannot make it home they should be remain where they are indoors.
"This is not a time for messing," he warned.
An Taoiseach Leo Varadkar warned earlier today that the weather presents a risk to 'life and limb'. He urged the public to heed the warning because of the whiteout the blizzard will cause.
Two Status Red weather warnings are in place for the event. The worst of the weather is likely to hit the east, midlands and southern counties.
A snow-ice warning for Munster and Leinster was updated just before 1pm on Thursday, March 1. Met Éireann say sub-zero temperatures and further heavy snow showers will persist throughout the afternoon.
Blizzard like conditions will develop in the southeast and south this evening and extend northwards tonight. Southern and eastern coastal counties will be worst affected.
The warning is valid from 1pm Thursday, March 1 to Noon Friday, March 2.
A similar Status Red Snow Ice warning is also in place for Connacht, Cavan, Monaghan and Donegal. It does not arn of blizzards but says scattered heavy snow showers will lead to significant accumulations in some areas. This warning expires at 6am Friday, March 2.
Met Éireann has forecasters have said the beast from the east is now directly over Ireland and the wind chill could lead to -10 degrees c. Gale force winds are likely to drive the blizzard.
It also warns that the thaw will not be quick and snow will linger over the weekend in parts.
The outlook in to next week is for the cold conditions to persist with light to moderate east to northeast winds and isolated wintry showers.
The type of cold spell that Ireland is experiencing could mean weather may remain frigid for some days to come.
Met Éireann is a weather forecasting partner of the UK Met Office. It has also issued Status Red snow warnings for Scotland, south west England and Wales.
