96L #2?

Early and mid last week I watched 96L Invest as it began to grow ever so slightly as it approached the northern part of South America. It then disintegrated into an open system as it moved further westward.

Now, there is a new 96L Invest on the Navy/NRL Tropical Cyclone page that is many hundreds of miles further to the east of where the remnants of the first 96L Invest would be.

Can someone explain two systems with the same name within such a close time frame?

Re: 96L #2?

A good question, but the answer is fairly easy. NHC provides NRL with the center coordinates for all Invests. On July 6th at 18Z NHC assigned updated coordinates of 10.9N 55.3W for the old Invest 96L - but it looks like NHC forgot to tell NRL to drop the Invest, so the Navy keeps the Invest active awaiting new coordinates or instructions to drop the Invest. Since that time, a new tropical wave has coincidentally moved into the image frame of the last coordinates for the old 96L - so it looks like a new Invest (and eventually it might be) but for now, its not. Hope that you were able to follow this.
Cheers,
