The Met Office has issued a yellow ‘be aware’ warning advising that heavy rain is expected in Argyll and Bute, and much of north-west Scotland, on Friday and Saturday.
The warning is valid from 1am on Friday until 9pm on Saturday, while the rain - thought likely to be heaviest in northern Argyll and Lochaber - is expected to be accompanied by strong southerly or south-westerly winds gusting up to 50mph.
The initial rainfall is expected to be followed by a drier interlude before further persistent and occasionally heavy rain develops late on Friday and lasts through much of Saturday in places.
As this article is published, the Met Office’s five-day forecast for Rothesay is predicting heavy rain throughout the early hours of Friday, and though drier weather is expected during the day, the rain - accompanied by some sunny spells - should return early on Friday evening.
The diet of sunny spells and heavy showers, some of them thundery, is expected to continue through most of Saturday, though the rain should ease off on Sunday.
The wind will also gather in strength through Friday, reaching 25-30mph - with gusts of up to 45mph - late on Friday or early on Saturday morning.
