Layoff notice, what does the 60 days mean? (Atlanta)

Our team was told about a closure date that is 10 weeks away. I worked as a graphic designer before this. I do not know if I should start looking now or wait for severance news. What did the workforce office offer?

I stayed for the retention bonus and looked for work on the side. It cushioned the gap.

Thanks for writing this out. I went through something close to it last year, and it settled down once I kept a simple log of every call and form.
