that usually happens on anyones rotors when it rains. It can even happen if dew settles overnight, perhaps with a vast change of temperatures-same kind of thing when you see dew/water on your windshield when you wake up for school or work in the morning. A lot of it could even be just rusting of settled brake dust. All very normal.

rain will do it over night, but High Humidity for more than 6 hours will do it too. If the relative humidity is inthe 70% or higher, you will probably see it 10 to 12 hours latter, especially if there was already a little bit of rust present.

This is true, I get rust on my rotors about half an hour after washing my car, a nice thin coat of orange.
