Storm Brendan could bring a danger to Tayside and Fife coastal communities from Monday into Tuesday.
A Met Office yellow warning for wind is in place in Angus and the Mearns until midnight, while the Scottish Environment Protection Agency (Sepa) says “higher than usual tides and large waves” will batter waterfronts.
The turbulent conditions could lead to “overtopping” of coastal defences in Tayside and Fife on Monday and Tuesday.

Power cuts and widespread travel disruption are also possible.
In Stonehaven, flood defences have been put in place at properties and sandbags have been made available to residents by Aberdeenshire Council.
Part of the town’s beach promenade has also been closed by police.
A cordon was set up on Monday morning with the area cleared due to concerns around the increasingly strong winds and sea swell.

Huge waves were also seen battering the Arbroath waterfront on Monday at high tide.
Storm Brendan, which is moving in to the UK and Ireland from the Atlantic on Monday, has prompted a string of warnings across the country from Wales to England, Northern Ireland and the west coast of Scotland.
The Met Office statement on the wind warning affecting Angus reads: “A widely very windy period expected Monday with some disruption to travel likely.
“Some delays to road, rail, air and ferry transport (is) expected, particularly for high-sided vehicles on exposed routes and bridges
“Some bus and train services affected, with some journeys taking longer. Coastal routes, sea fronts and coastal communities affected by spray and/or large waves. Some short term loss of power and other services.”
Sepa flood alerts are in place for Dundee, Angus and Fife. A more serious warning is in force for Stonehaven.
Sepa says there is “a risk of significant coastal flooding on Monday and Tuesday due to higher than usual tides and large waves” across the local area.
The Dundee and Angus alert reads: “This will increase the risk of flooding to low lying land and roads and could affect exposed coastal properties.
“There could also be wave over-topping of coastal defences and causeways.
“The periods of greatest risk are around the high tide which occurs at Arbroath around 1pm on Tuesday.”
In Fife, the risk is greatest at high tide at about 3pm on Tuesday.
It comes after the Met Office issued a snow and ice warning for Perthshire and Angus on Tuesday.
