PVC door bent a little - water coming in at bottom

[record]

My PVC front door does not sit snugly in its frame at the bottom. Basically, it curves out a little bit from the frame in the middle. This results in rain getting in as the seal is not tight.

Does anyone know if there is anything I can do about this?

Thanks for any help.

The hinges can be adjusted.
