HVAC drainage question

Ok i know that the HVAC system on w's gets its fresh air from the opening on windshield cowl, but lets say it rains/snows does that rain go down through the hole into the car and back out through the AC drain hose?

I finally got a look at the drainage today since it was above freezing, I took a 500 ml bottle and filled it with water, then i poured it on the cowl area. Only the part right above the brake booster. It seems the water just poured out by the drivers side front wheel. Did some of it still go in the interior?
