Update: The Navy is backing off of its upgrade of Invest92L. We'll keep on eye on the system and report more later.
Right on time we are seeing more activity in the Atlantic. A very strong easterly wave just rolled off of Africa and is already starting to develop. I usually wait until systems clear Africa before discussing them, but this one has different ideas. A quick look at the satellite imagery shows that the convection is not very strong right now, but the circulation is fairly well organized.
Sea surface temperatures are warm enough in the area, but it can't move very far north if it is to survive. Water just a few hundred kilometers north is significantly cooler.
Advisories are expected from the National Hurricane Center any time and we will prepare model charts at that time.
