Without seeing the tree it is hard to tell wether it is viable or not. I think the weather is affecting not just trees but a lot of plants this year. I have a client that planted a beautiful Robinia a couple of years ago and although it had a great year last year, it is not looking too good this year. Give it until the end of May to see if it improves. However, I echo marshmello's comments that if it is in any way dangerous it needs to be addressed immediately.
