Appreciate the folks that are keeping an eye on these two tropical waves. Invest 90L was near 13N 46W at 28/15Z and may be developing a circulation center at about a degree further north. This system has good structure and the potential to become a Tropical Depression in the next day or two.

Invest 91L is in the far eastern Atlantic just off the African west coast near 9N 19W at 28/15Z. This wave has excellent structure and despite the far eastern location, it could become a Tropical Depression at any time in the next 24 hours. Both waves are moving westward.
Cheers,
