Nicola Sturgeon has hit out at new 'stay alert' messaging by the UK Government and does not want it deployed in Scotland.
The First Minister said that advice north of the border remains to "stay at home" other than for buying food, getting medicine or exercising.
She said it would be "catastrophic" to drop the "stay at home" advice and that the current messaging is 'clear'.
“I don’t know what ‘stay alert’ means,” she said.
The leaders of Scotland, Wales and Northern Ireland said they had not been consulted over the "stay alert, control the virus and save lives" slogan.
However people living in Scotland will be allowed to exercise outdoors more than once a day from Monday but most of the other lockdown measures will remain.
The SNP First Minister also said that she does not expect schools in Scotland to be reopened on June 1 and confirmed that a 14-day quarantine will be enforced for those who fly in to the UK.
Boris Johnson is expected to say similar in his speech to the nation this evening.
“We are giving these messages now for very good reasons, because we think it is the best way to control the virus,” Ms Sturgeon said.
Communication between the UK and Scottish governments was "ongoing" she added, but she had not yet seen Downing Street’s official plans for easing the lockdown.
Announcing the extension of exercise allowed at the daily briefing, the First Minister said: "From tomorrow, that once a day limit will be removed.
"If you want to go for a walk more often, or to go for a run and also a walk later on in the day then you can now do so."
The First Minister added that the extension did not apply to those who have symptoms or are living with someone who is showing symptoms, or those who are in the shielding group.
Ms Sturgeon said it was to be used for exercise only and should not be used for "sunbathing, picnics or barbecues".
She added: "The fact that you're allowed to exercise more than once is definitely not a license to start meeting up in groups at the park or at the beach.
"Doing that really does risk spreading this virus."?
The government's 'stay alert' messaging, first unveiled last night, has been widely criticized for its vague nature.
A No 10 spokesman said the public can stay alert by "staying at home as much as possible", "limiting contact with other people" and keeping two metres apart where possible.
"We can control the virus by keeping the rate of infection (R) and the number of infections down," the spokesman said.
Official guidance from the Department of Health (DHSC) said that people should also continue to work from home where possible and wash their hands regularly.
The Prime Minister's official Twitter account said: "Everyone has a role to play in helping to control the virus by staying alert and following the rules.
"This is how we can continue to save lives as we start to recover from coronavirus."
But Professor Til Wykes, vice dean of the Institute of Psychiatry, Psychology and Neuroscience at King's College London, said the phrasing of "stay alert" was unclear and open to misinterpretation.
"The one thing that helps the population is clear, concise and accurate messaging," he said.
"This one is concise only. The previous message to stay home was at least clear. What does stay alert mean?
"It will just be confusing, be open to misinterpretation and likely to increase risky behaviour - that means taking risks that will affect everyone and increase infections."
Leaders of all the UK devolved nations say they will continue to endorse the "stay at home" message through their respective administrations.
Scotland's First Minister Nicola Sturgeon tweeted: "It is of course for (Boris Johnson) to decide what's most appropriate for England, but given the critical point we are at in tackling the virus, #StayHomeSaveLives remains my clear message to Scotland at this stage."
