The Island's Met Office is warning people to be prepared for snow this weekend.
Wintry showers and sleet are forecast for much of the week - but Sunday is likely to see significant snowfall.
Forecasters say the snow is most likely on high ground, and could be deep enough to see drifts forming in strong winds.
The Ronaldsway facility says rain or sleet is more likely on lower ground, although that could change as the week progresses.
