The Department of Infrastructure's gritters have been out on the Mountain Road and the minor routes which run off it this morning.

The Department of Infrastructure, emergency services, Met Office and the Department of Education are meeting at 2pm to discuss how to deal with the weather.
Education plans to make an announcement about the Island's schools at or around 4pm.
