About a half-hour ago, I heard a deep groaning noise, like the timbers of an old wooden ship at sea make. That lasted the space of several seconds. Half a minute or so after that stopped, I heard a deep 'tock-tock-tock' sound (definitely not some sort of bug ticking), which also sounded like ship's timbers. I went to check on the other side of the wall, but it was quieting and I could barely hear anything before it stopped completely.
Is something going on with the wooden frame of my house? I know houses make odd noises all the time, but this house was built in 1999 and I bought it 9 years ago and it has never made noises like this before now, even during wind storms with gusts above 90mph. I should also note that I live on the Washington coast where it is nearly always damp and wet, though we did have a very dry summer and the rains started in earnest about a month ago.
