Hmmm......well if I know its going to rain I carry a regular old plastic baggie to throw over the camera to protect it... I don't have one of those nice expensive thingies you can buy to protect from water....also I carry a big green garbage bag in my camera bag, this keeps my knees dry when I'm scrunched way down taking pictures of mushrooms or that sort of thing. As far as long exposure and that goes, bring your tripod you will need it, (which I'm sure you knew). I love shooting in wet weather the light is nice and diffuse....and if you have water falls around that would be the best time to try and capture them.

I am, therefore I create.......
