The Met Office has issued a yellow alert for strong winds covering most of the country as the first storms of Autumn roll in.
They are expected to bring gusts of up to 60mph and residents have been advised to prepare for gales.
But the turbulent weather could prove handy for water sports enthusiasts as an annual sports festival gets underway.
Windfest started yesterday at Barassie Beach in Troon and runs until tomorrow, with 10,000 spectators expected to watch sports including surfing and kite-surfing.
As the Evening Times went to press all events were scheduled to go ahead as planned.
Forecasters say the weather is predicted to be at its worst on Sunday afternoon.
Heavy rain will move in from 7am, lasting most of the day, but this will be coupled with strong winds from around 4pm.
Council officials in Inverclyde, which was badly hit during storms in July, are installing flood gates to minimise any damage caused by the expected deluge.
The gates will be used by businesses near the West Station in Greenock, a known flooding hotspot, to stop water entering shops.
Temporary flood barriers are also being primed.
James Wilby, a forecaster with MeteoGroup, said: "There will be gale-force winds in northern, western and central Scotland, with sustained speeds of 35mph, but gusting to 60 mph."
