Dear group,

The top of my window is leaking water into my bedroom. I know that I
will need to caulk it, and I have caulk, however, I live in a very
rainy area and it's the rainy season. What should I do to create a
relatively dry environment for the caulking to even try to dry out? If
anything, trying to protect it from the outside would be extremely
difficult, as it is a third story window.

Thank you for your time,

N

ps. Also consider I am a novice to home repairs.
