Leaking Door

Hello Guys,
This weeks project is working on a outside door that leads on to a elevated deck. Water leaked in under the door rotted some of the subfloor and rooted the old wooden threshold.

I will show you what I have done but I am looking for pointers to make sure I am doing it correctly and for any hints on what would help me.

Here you can see the rotted subfloor after I had removed the old threshold. The water had been running along the decking under the threshold and attacking the subfloor. Water was also able to be blown under the door as the weather strip on the door had been warn away

I cut out the rotted sub floor on the right hand side of the door. Lucky for me the part that was rotted was just over a joist so I did not have to replace a large area. I replaced this with some treated wood. I used some flashing to try and protect the sub floor and make sure water would not come in under the threshold.

I now need to work on replacing the threshold, I had some problems trying to find a threshold that would fit the space. I found this one that worked it even allows you to raise the wood weather strip

Now my problem on what to do. The weather strip sits about half a inch away from the door jam.

You can see when the door is closed the door wont be up against the wood weather strip it would have been a nice feature to use (I am not sure if I can do any thing to fix this.

On closing the door there is still quite a gap under the door.

I am not sure whats best to do now plane a bit of wood to bring the threshold up ?. I had looked for a U channel weather strip but the door is 1inch 7/8th wide wrapped metal door my local hardware store does not carry any thing that wide.

Please let me know what you guys think if I am doing any thing wrong and also how I should go about fixing the gap under the door.

Once I have fixed the door I need to work on the outside not sure if I can do any thing there to stop the water being blown in.

You need to install a door pan similar to this one.
Install a door sweep to close the gap.

Thanks for the reply kwikfishron, I will have to have a look around to see if I can get a door pan, will the door pan need to be attached to the rough opening or could it be possible to attached to the current door jamb. What is the correct method to attach the threshold as I would not want to piece the door pan and ruin it role in keeping water out.
