There's a yellow weather warning in place for frost and ice, with some roads closed as a result.
The Beinn-Y-Phott road from Brandywell Cottage to the Mountain Road, and the Tholt-Y-Will road from Sulby Glen road to the Mountain Road, are both shut.
The Department of Infrastructure says these will remain closed until 8am on Monday at the earliest unless an extension is applied.
The all-Island weather warning is currently in operation until 3pm tomorrow (9 January).
