Another three people with coronavirus have died in Scotland with 350 new cases recorded overnight.
The new infections amount to 5.3% of newly-tested individuals.
The latest figure is the highest daily increase since April 25, when 354 new cases were recorded.
A breakdown shows there has been 116 new cases in the Greater Glasgow and Clyde area.
There have been 56 new cases in Lanarkshire and 80 in the Lothian region.
The latest fatalities take the death toll among Scots who died within 28 days of their positive coronavirus test to 2505.
Nine people are currently in intensive care and 64 people are in hospital with recently confirmed Covid-19.
Commenting on the figures, the First Minister tweeted: “There will always be fluctuations in daily figures – that’s why we look at 7 day averages to balance out variations in testing etc.
“Even with that caveat though, today’s report underlines fact that COVID is rising. @scotgov is considering over w/e what further action is needed.
“Given serious situation across UK, I have also asked again that a 4 nations COBR meeting takes place over next 48 hours. While each of the 4 UK nations will reach our own decisions – rightly and properly – it makes sense to seek as much co-ordination and alignment as possible.
“We know from experience earlier in the year that speed and decisiveness of action is important in the fight against COVID, so @scotgov will seek to reach considered decisions as quickly as possible, and I will update as usual through my daily briefings.
“In meantime, I ask everyone across Scotland to be extra careful. Minimise interactions with other households and keep to a maximum of 6 people from 2 households (if in Glasgow, E/W Dunbartonshire, E/Renfrewshire and N/S Lanarkshire please don’t visit other households at all)”
The latest significant rise comes after Nicola Sturgeon signalled “hard but necessary decisions” will likely have to be made in the coming days to head off surging cases of coronavirus.
She said on Friday the country is at a “critical moment” and urged the public this weekend to “rigorously” follow all the public health rules and advice.
She warned Scotland is “facing the risk again of exponential growth in Covid” and that the situation is “deteriorating”.
