Nicola Sturgeon is expected to announce new measures at Holyrood to tackle the spread of coronavirus across Scotland.
The Scottish First Minister has said she will decide on further restrictions with her ministers following a Cobra meeting on Tuesday morning.
It comes after four chief medical officers across the UK nations decided that the Covid-19 alert level should be raised to four.
Ms Sturgeon tweeted on Monday: “4 UK CMOs – inc @DrGregorSmith – agree raising of #Covid_19 alert level to 4.
“I’ll participate in COBR meeting tomorrow am, after which @scotgov Cabinet will agree measures to bring virus back under control in Scotland.
“I’ll then offer statement to @ScotParl tomorrow pm.”
The First Minister previously said coronavirus is spreading again in Scotland and “further and urgent action” is needed to stop the increase, warning if left unchecked it will lead to more cases, people in hospital and deaths.
She said the Scottish Government is prepared to introduce “a package of additional measures” but will aim to avoid a full-scale lockdown such as the one imposed in March.
Ms Sturgeon will set out the measures to MSPs in Parliament from 2.20pm on Tuesday and will make a televised statement at 8.05pm on the BBC after remarks from Prime Minister Boris Johnson.
On Monday, she set a 48-hour deadline for a co-ordinated approach to be agreed between the UK’s nations.
She added: “I will be clear that I am willing to allow a bit more time for four-nations discussions to take place before making final decisions for Scotland.
“But I will be equally clear that the urgency of this situation will mean that we cannot, must not and will not wait too long.”
On Monday evening, the UK Government said pubs, bars and restaurants in England will be forced to close by 10pm from Thursday and restricted to table service only.
Restrictions were also announced in Northern Ireland to prohibit mixing of two households indoors, except for single-person bubbles and certain other exemptions, from 6pm on Tuesday.
No more than six people from two households can meet in private gardens.
