What is going on with WN788?

I go onto Flightradar24 to check in. As I am a Southwest Airlines fan, I see a Southwest aircraft flying pretty low so I assumed it just departed Baltimore for Islip or Albany. When I touched it to see it’s destination, I found that it is in a holding pattern just outside Philadelphia (KPHL). I find this to be pretty odd as the aircraft is rapidly descending. Does anyone know any information about WN788?
