I think everyone (on the east coast) should be aware of any named tropical systems. Even if they aren’t going to hit the US. It might be my weather obsession, but every once in a while, they make landfall. Then you can be smug and say, ‘I knew Issac when …’.
Another fun thing to do, is reminisce of anyone you knew with that name. I don’t recall meeting any Leslie’s. The first one that comes to mind is Leslie Knope. So watch some Parks & Rec.
