Weather:
There has been heavy snowfalls in much of the midlands and Lenister this afternoon, although they did not reach Dublin.
After earlier snow and wintery showers there were some sunny spells in parts of the west and northwest later today.
Temperatures could rise to between four and seven degrees in the west of the country but will remain around zero in most areas.
Tonight, wintry showers are expected to move eastwards across the country with further snow accumulations. Temperatures are forecast to fall to about minus six degrees. A sharp and severe frost is likely to render roads and pavements icy again and freezing fog may occur in some parts of the country.
