Covid-19 infection rates will keep rising if schools and the hospitality sector remain open, a paper from the health minister has warned.
Advice from health and scientific experts has been submitted by Robin Swann for Stormont ministers to consider.
The weekly meeting of the powersharing administration, scheduled for Thursday, was brought forward in an indication that decisions on fresh restrictions are imminent amid rapidly increased virus spread.
Seven further deaths and another 863 positive cases of Covid-19 have been reported by the Department of Health today.
The latest deaths bring the toll in Northern Ireland to 598.
Chief medical officer Dr Michael McBride and chief scientific adviser Professor Ian Young have already recommended a country-wide lockdown lasting four to six weeks.
The aim is to reduce the reproduction rate of the virus to below one infected for every person diagnosed.
Ministers have been warned that it is not considered likely that the R rate can be less than one with both schools and hospitality open.
Officials previously urged school closures for a period within the lockdown, though not necessarily for the entirety of it.
They have said action needs to be taken within days and have identified the six-week lockdown as providing the best chance of Northern Ireland reaching Christmas without the need for another.
First Minister Arlene Foster said she will listen to "all advice" to take a "balanced response".
Mrs Foster said she spent Monday "striving for unity" within the Executive ahead of a meeting today.
She also indicated she is not in favour of closing schools.
The suggestion of a six-week, Northern Ireland-wide lockdown was questioned by a senior DUP MP.
Sir Jeffrey Donaldson queried why such a move would be required across the north, given the marked variations in infection rates in different areas.
