This randomly began on my way to work. It's extremely loud. Any idea what this may be? I took a short video of the sound. Thanks in advance.

does the sound change when you increase throttle?
you can eliminate/isolate the serpentine belt tensioner by using a 16mm open end wrench and pulling back on the tensioner. Remove the belt and see if you feel/hear any rough spots on the bearing as you spin the pulley.
although i'm pretty sure that's not it, it won't hurt to eliminate it from the diagnosis.
Engineers do it better.
I'm gonna have to go with your first guess on this. Water pump. I can't back it up but that sound and reading posts in the past makes me want to say that it is the water pump. If so sorry to hear this. Look for blauparts timing belt kit with the thermostat ($280) included and find a buddy and get this service out of the way. Hoping you can do this yourself that is. Sure it's early but you'll have everything apart anyways, mine as well do it all. Good luck!
I'm afraid it might be. I would assume it is the same billable labor as the timing belt service which I believe is and 8 hour job (not really but that is what they will charge you). And then you have to factor in practicality as the timing belt will be accessed to get to the water pump. That is why I say go ahead and replace everything. Let's hope it's not the water pump first. ; )
This is the guy I got:

I claim not to be a tech at all but as much as I've been on these forums and as much work as I've done to my car I feel like it sometimes. I really doubt it would be your pcv with about 99% certainty. Those don't make that noise. If it was your pcv it would be more performance oriented. Like fuel cuts or the like. As if you had a air leak.
Was it a broken rear breather tube?
