If you have a package on the way via the U.S. Postal Service this weekend, it might take a little extra time to get there. And that is because the USPS is suspending almost all service and shutting down its offices on Thursday for former President Jimmy Carter’s national day of mourning.

Here’s what that means for post offices in North Carolina. USPS facilities in North Carolina and across the country will be closed on Thursday, except as needed for “limited package delivery,” the postal service said. That means regular mail delivery will be suspended, along with retail services and office activity.
