Drowning alert

[Aalwein]

Is there an add-on that would allow me to get a audible/visible alert when I'm about to start drowning? I believe MSBT can alert me when I already am drowning (which is usually too late!), but I would like to create an alert when I get below 45s breath remaining. I know it's very situational but damn if I don't seem to always forget my breath when I'm fighting... call it a one track mind bent on maximum dps. Can Power Aura or MSBT be set to alert when the breath meter drops below 45s?
