Update: I pulled up the driver's side carpet and traced the leak. It is coming from behind the firewall, right in the center where the steering column is. I then found a plastic hose I had left on the windshield vents since the time I SeaFoam'd the engine back in 2009. Coincidentally, this is about the time the leak in the car started so I wonder if that plastic hose was blocking the water from draining out as it should.
I dried the carpets as much as I could last night and fortunately it's raining here again today. I'll check again tonight if the leak is still there.
