during a heavy rain storm, where is this coming from?

who knows, crawl under there and look or run a hose over the windshield and look up in there

Take your wipers off, remove cowl cover (6 screws) look on passenger side there is a fresh air inlet for the heater. Just past that towards the outer fender is a drain area, see if that is plugged with tree debre. If not open water will back up to the heater air inlet.

My guess is the heater core or heater core hoses.

Stupid me. I was reading this in Mobile format and missed you said while it was raining heavy. Disregard my comment.
