It sounds like the rain finally took its toll!
What happened, likely, is that the rain started out by refreshing the plant, but when it became too much for too long, started to cause suffocation and rot.
At this time, you will need to repot into a cactus soil, instead of potting soil. Potting soil will be too thick and likely full of nutrients to support the plant. Treat with a fungicide, as well. Make sure that the plant dries, thoroughly, between each watering.
