The Columbia River Bar is on Red status, so what happens now?

Yesterday the Columbia River Bar was on Red status, per the Columbia River Bar Pilots. It's the most severe restriction on ship traffic they can impose, and it means most, if not all, ships will be restricted from coming in or out of the river till the weather improves.

We have a big potential ship schedule today, meaning lots of ships want to enter and leave the river. Today we'll talk about the effect a temporary, weather-related closure like this has on vessels, and what they do while they wait.
