USJ on a rainy day

I’m going to USJ today and looks like it’s going to be raining all day. Booked the ticket a month ago

What rides are likely to be closed? And if I have an express pass for a ride that is closed, can I use it on another/get a refund?

Any other tips to make the most of a rainy day are appreciated. I’ve got an umbrella and a change of socks packed
