I'm laughing because I used that exact same phrase: "shit umbrella". Like some of the other replies mentioned, telling your team it's raining is great. The balance I found was to let them know what's coming and why but to let leadership's "pivots" to stabilize for a few days before sharing the unfiltered shit stream with my reports. This meant that the team still knew what was going on early but didn't panic as much when there was a sudden crazy random request from leadership that would be highly disruptive.
