Development a little slower than originally expected - environment ahead of the system is still dry and the forward speed has remained on the high side. Otherwise, the future Erika is holding together nicely and has developed deeper convection, primarily to its NNE, this afternoon/evening. Movement, with consideration for a slight wobble, has been almost due west for the past 6 hours. Center is still fairly easy to locate on IR and at 23Z it was at 13.4N 52.9W. Wouldn't surprise me to see a slight southward adjustment of the track in the near term and a more northward adjustment of the track in the far term (hard to ignore the UKMET). I'd still anticipate hurricane strength in 72 hours - system seems to be far enough north to avoid the disruptive effects of northern South America.
Cheers,
