scattered trees and power lines. Power outages are likely. Travel
will be difficult, especially for high profile vehicles.
What are you supposed to do when you’re responsible for the safety of your students and staff? Also, I don’t think the early dismissal days are pointless, but I’m not well versed enough to say what a half day looks like.
