What I don't get is why they didn't retroactively name it Arlene. Usually these things aren't identified until well after the season is over, which means they wind up not getting a name or even a numerical identifier (or getting one out of order? not sure how that works). In this case, since they identified it before any other storms formed, they retroactively assigned it the AL01 identifier - but for whatever reason didn't retroactively assign a name. So now, if this depression gets named, we'll have AL02 Arlene - and if it doesn't, then we'll have AL03 Arlene. It's going to drive me nuts having a number that's off from where we are in the alphabet, isn't it - especially now that I work for a company that quality controls hurricane data and issues analyses for them, so I'll be dealing with these identifiers a lot this summer and fall.
