Coastlines around the north and north-east have been placed on flood alert, with high tides expected over the weekend.
The Scottish Environment Protection Agency (SEPA) yesterday cautioned residents to be ready for potential disruption.
Duty Hydrology Manager for SEPA Vincent Fitzsimons said: “Unsettled conditions are expected over the next few days, with a risk of flooding in localised areas along the east coast.
“The risk is particularly relevant to low lying coastal communities today in Caithness and Sutherland, Easter Ross and Great Glen, Findhorn, Northern Aberdeenshire, Nairn, Moray and Speyside due to high tides in the Moray Firth area.”
As the weekend progresses the high tides are expected to spread southwards, and experts anticipate that by Monday the worst-hit areas will be in the south-west and north-east.
Mr Fitzsimons said: “We will continue to monitor the situation very closely and update emergency responders and the public as required.
“We would encourage members of the public to remain vigilant and be mindful of the conditions in their locality and when travelling.”
Experts have been warning of “supertides” around the spring and autumn equinoxes this year.
A rare alignment of the sun, earth and moon – called the syzygy effect – will result in a much higher gravitational pull on the oceans, meaning tides could be up to a foot higher around Scotland.
The flood risk in areas such as the Moray Firth, Wick and Aberdeen will be at its highest level since 2012, with 21 high tides above the normal threshhold forecast for the granite city, compared to 14 last year.
