Honda Accord 2003 floding when rains

I have a Honda Accord model 2003, 26000 miles, V6 engine.
When it rains the floor is just flooded with water, mainly the passangerside and back seats floors.
I tried to hose the car and found out that when I put water on/below the front windshield, water basicly flows into the car floor creating a poddle on the floor.

I saw somewhere that there should be a drainage hose from the bottom of the windshield an to the bottom of the car, I can not find it. But when I put water on the windshield the water comes down on bots sides of the car, somewhere behind the front tires, but I see no hose line there.

What can I do, can you help?
