I work from home but I took the bike out and explored a little yesterday. I guess it never rains here so it makes sense, but traffic in general was struggling.

When it first starts raining, it's slick, but once all the crap gets washed off, you have a surprising amount of grip in the wet. It's really not that different from when it's dry except it's going to be much more difficult to catch a slide. The mental hesitation is a lot bigger than the actual danger. Only thing to really watch out for are metal things (manhole covers, cattle guards, etc). If you ever get the chance, do a track day in the rain; it's eye opening.
