Sry for the late post. Indeed this is an WA for traking your HST/Riptide/Ancestrial Guidance and most important your Cloudburst totem. Everything except the Cludburst totem is just basicly keeping track of your cd and shows you when it is up. So just press Riptide/HST when this WA shows up. The Cloudburst totem WA does this as well but also shows you the time for how long it will be up and gather healing and as well the amount of healing collected.
Here are some pictures of the WA and how it should look like.
Maybe there are some problems with different WA versions. Updated mine and made a new string :
Thanks for the feedback and sry for not posting pictures and everything in the first place.
