I can tell from past experience that rating and ranking from the previous year is typically used unless they have the latest data from this year ready before the layoffs. They will generally cut people rated 3s or low 2s.
If your manager thinks you are leaving their team you are at risk. If you recently left your old team and have not been rated and ranked by your new team you are also at risk. Don’t change positions right now within the company.
Don’t let anyone know you are even thinking about it. Wait until the layoffs are done to look at moving within the company. If you were rated a 3 last year get your resume ready and get a head start on finding a new job. If you were a 2- don’t be surprised if they walk you out.
