If you have more than one American Upper Left Coaster, they'll probably have mentioned once of twice that is has been raining a bit. What's been going on is one of the most interesting weather phenomena we get here, though it can be disastrous.

The "Pineapple Express" is not the name of the storm we just encountered. It's a well-known weather pattern here, so named because the jet stream brings humid air out of Hawaii up into Oregon and Washington. It moves in like a freight train.

I haven't been able to dig up exactly who gave it that name. Perhaps George Taylor knows. But the most famous Pineapple Express events have been the 1948 Vanport Flood, Christmas Floods of 1964-65 and the 1996 floods. The Columbus Day storm of 1962 was not a Pineapple Express, but a typhoon.

That's another thing. Here on the left coast, we get typhoons, not hurricanes. It's a Pacific vs. Atlantic thing.

Here's more than you want to know about the Pineapple Express.

Class dismissed until Spring, when we'll learn the difference between a casino and a Spring Chinook Wind.
