St Mary's RNLI has warned of "huge swells" tomorrow as the remnants of Hurricane Ophelia sweep across the UK.
A severe weather warning has been issued by the Met Office for Monday, while Five Islands School has advised parents of a possible road closure.
St Mary's Lifeboat Station has now added its own warning, posting on its Facebook page: "As I'm sure most are aware the region is highly likely to be affected by ex Hurricane Ophelia as it passes to the west of the islands.
"This was the most easterly Cat 3 Hurricane ever recorded in the North Atlantic with at its peak sustained winds of 115mph.
"Although its downgraded from a Hurricane it still is packing some storm force gusts and also kicking up some huge swells.
"Please take great care tomorrow in the strong to storm force winds and in particular stay away from the direct shoreline due to the swells predicted,and the seas that will build through the day.
"8-10m swells at 14 to 15 seconds are very large and powerful waves, the largest predicted at HW on monday afternoon. Stay Safe...."
