2008 Tahoe drivers side floorboard floods

[Ed Alexander]

Hey all, I have a 2008 Tahoe LT and have had my drivers side 2008 Tahoe's drivers side flooding with water with heavy rains. In short, I checked and sealed the doors weather stripping and blew out the drain already. As you will see on the photos it comes out of the middle under where my hand is. Any direction and troubleshooting would be much appreciated. TIA

One possibility, cowl sealant can be bad..
Need to remove wipers and cowl trim to inspect..
Someone had a leak behind the fender part of the cowl once as well..
