How local shipping gets back to normal after bad weather on the bar

We've had some interesting weather this week, including a thunderstorm warning that didn't quite materialize. But along with that storm came bad weather at sea, so difficult that the Columbia River Bar was on red status for the past day or so. That means ship traffic has been halted going in and out of the river temporarily, until sea conditions improve.

Ships will starting moving again today, and that creates some interesting patterns relating to ship transits, in the aftermath of bad weather. So we'll talk about that today.
