What rides will be closed tomorrow?

Hi! I’m going to Universal tomorrow for the first time in like 7 years and I’m looking at the app and it says mummy and jurassic world has extended delay. Does this mean it’s not gonna be open from xyz date to abc date? or is that just for today because something went wrong earlier and they need time to fix the problem and then the ride will be back up? also just any information i should know of before hand would be awesome to know!! :):) thank you!!
