The letter, published by Bubble Wales, suggests that the lockdown, which will be similar in nature to the one put in place in March, will be announced on Monday and would last until Sunday, November 8.
That means the lockdown would be in place for 17 days.
Health Minister Vaughan Gething said a final decision has not been made but discussion are ongoing and ministers were meeting on Sunday afternoon and Monday morning to discuss the way forward.
First Minister Mark Drakeford is due to take the Welsh Government briefing at 12.15pm on Monday.

Dr Giri Shankar, incident director for the Novel Coronavirus (Covid-19) outbreak response at Public Health Wales, said: “Cases of coronavirus continue to rise in all parts of Wales, including in areas where local restructions are in place.
“The public health message has not changed and is as important as ever; it is vital that people in every part of Wales stick to social distancing guidelines, that’s staying two metres away from others, avoiding socialising with people outside your household, and washing hands regularly.
“They must also self-isolate immediately when asked to do so.”
