Currently Baja California is level 4 in the local scale. This allows non-essential operations. I can't find any data that says any of the ports
DCL will sail to (Ensenada, Cabo San Lucas, Puerta Vallarta, and Mazatlan) are closed.
The first cruise out of SD is 9/24. It's a 2N to Ensenada. Per previous social media posts the Wonder has a berth agreement in Port Everglades through 8/20. A revenue cruise through the Panama Canal is 14 nights, but that includes 5 days in port. It's probably safe to assume that a non-revenue transit would take about 10 days. So, it's possible that the Wonder could be in SD the beginning of September. There have also been posts from CMs saying that they are flying in to SD the end of August. That would line up with them quarantining for two weeks before starting test cruises.
I think the first indication will be if and when the Wonder leaves Port Everglades for SD. If they haven't left in two weeks I would start to get worried.
