Location of water leak was not clear so I stuffed the edge of the carpet with paper towels then dumped a bunch of water on the windshield to simulate a downpour and checked for wet spots on the paper towels.
Did not detect a leak from dumping water on the windshield, but then dumped water at different locations until found that this rust hole in the passenger front (notice antenna cable) is letting water into the cabin:
