Isn't Season of Storms officially translated into English already? Not sure but in UK you can buy the book without any problem (not sure how it is in US)
Im not in the US. and no sadly its not officially translated yet. they have yet to translate the other books from the saga as well before working on that. I mean The Swallow's Tower will be released officially in english in 2016, then there is Lady of the Lake, and then this. if they even decide to work on it.
