So its raining out again today, I went out to make sure the roof was not leaking, all is well with the roof but I see I have some water coming in under garage door.

The floor is made of osb (oriented strand board ) ,so it will eventually blow out from getting wet. I painted the threshhold with Kiltz Latex Primer, a Temporary fix until I can Figure out what I should do.

Any suggestions about how to solve this would be appreciated.
