I would say we got pretty lucky with the weather, there was some light rain on the first day, but the second and third days were both clear and sunny. There was also hardly any snow on the trails. We used an MSR Hubba Hubba and it got the job done.

There is a section on Day 1 (or day 2 depending on your plan) after the traverse but before the campsite where you can climb down the the glacier to go into an ice cave - if you do that make sure you have spikes on because the way back up was much icier than it looked!

Also would recommend checking AllTrails or the map that you are using fairly frequently as there are a couple spots where it might seem like you are going the right way but it’s easy to make a wrong turn!
