Talking to Advisor about Transferring

I have a meeting with my academic advisor in a couple weeks to talk about what classes I’m going to take next semester. I am seriously considering transferring after next semester, that is from a four year bachelor program at my current college to a four year bachelor program at another college. I’m currently a Sophomore and I really don’t think my current school is a good fit. Should I send her an email beforehand about my desire to transfer to give her a headsup?
