    Figure 2 at top of page, shows a weatherproof, in-use outdoor electrical installation, incorporating 2 receptacles in the weatherproof box, only one of them is a GFCI type.

There are many types of weatherproof and rainproof covers, Figures 7 and 8. But you should consider using a weatherproof or rainproof "in-use-cover". These covers are designed to keep rain water from entering the outlet (receptacle) and causing a short circuit when there is a cord plugged into the outlet (receptacle).
