That's KOOL, your magnetic Hurricane tracking chart.
I've always lived weather stuff, even as a kid. Stated when I was around 9 years old. Living in the SF Bay area. Years later, from 7-74 to 5-84 I lived in Half Moon Bay, CA. Great funnn watchin' the stormes coming in off the Pacific ocean, and the fog too. I had a weather station mounted up on the roof.
I have one of these on my roof now. You should get one, it really neat!
