Significant accumulations of snow are possible at all levels
An amber weather warning is now in place for snow.
Adverse weather conditions are expected to affect the Island between 12pm tomorrow and 6am on Friday.
Snow, which will often be heavy, is likely to become persistent across the Island by Thursday afternoon and will continue through the evening and into the early hours of Friday.
Significant accumulations of snow are possible at all levels and this will be accompanied by strong to near-gale force east to northeast winds leading to blizzards and drifting.
This will especially, but not exclusively, affect high ground and the west of the Island.
Cable icing could also be an issue for overhead conductors in some locations.
Ronaldsway Met Office says there will be a high risk of disruption to travel and network services including power and communications.
