Earlier today, NHC wrote their final advisory on Erika, which was downgraded to a Tropical Depression on Thursday. In the face of strong mid-level wind shear, the low-level circulation was completely removed from the mid- and upper- level circulation and convection. The remnant circulation is now south of Puerto Rico and will we monitored for any signs of redevelopment.
Elsewhere, a potent easterly wave is located just south of the Cape Verde islands and tracking W at 18kts. There is a 1012mb Low associated with the wave. On satellite imagery, it has an impressive presentation, both in the low-level circulation and attendant convection.
However, most computer models do not develop THIS wave, but rather the one behind it, currently over western Africa.
