Where the Rain is Falling

[wotw]

For those who have asked, here is an extremely rough sketch of my downstairs, with ongoing downstairs rainstorms marked in red, and the location of the upstairs rainstorm marked in blue. (Warning: This is certainly not to scale, has none of the angles right, etc. Beyond that, I am notoriously directionally challenged and it would not be surprising if I've put entire rooms in totally the wrong places. But I think this is roughly correct.)

I should add that the blue upstairs rainfall is stretched out along a line roughly 25 feet long.

Edited to add: And the fifth is in the laundry room, nowhere near any of the others....
