Morphology

weathertight = weather + tight (semi-transparent) = weather + tight

The metaphorical extension from a physical seal to an abstract sense of being 'secure' or 'unable to be criticized' is not fully literal but still inferable.

Etymology

Weathertight uses the image of being 'tight against the weather' to describe plans or arguments with no weak points. A helpful way to remember this sense is to think of a case so tight that nothing can get through, so it is 'completely secure'.
