Looks like TS Marco was a lot of hype, it's weakening quite rapidly.

Marco was very small but it was still a Hurricane for a brief time. It was just a matter of time until the shear killed it off but man, did it go out quickly once shear got to its core! Still got close enough to help dump 7+inches rain parts of the panhandle. I imagine at 5 they’ll declare it gone or Depression status.

Recon still finding 40+mph winds NE of the center East of New Orleans so retains TS status. Some additional scattered showers and possible brief tornadoes will continue to be possible tonight.

It was never gonna be anything from the get go like the last many systems. Now with a upper level high in the the gulf and less shear the TS near Cuba may just blow up a rapid rate. Once we see good out flow and exhaust then we will have a good system that should wrap around itself and look like a tropical system should and not some loop sided torn up mess with all the weather well away from the center.

Parts of the area Marco dumped rain on were looking at the early stages of a drought so it was probably at least partially beneficial. Now they're hyping Laura up the same way so we'll see what happens.
