OK, now I see it. Laura's Western flow barreling in.

MIMIC-TPW2

Just... really trying to understand why this won't go NE. It's north of the main steering influence that would send it west.

Marco is now a naked swirl - convection having been blown off to the NE. Will be interesting to see if it can recover at all.

He’s dead. The weakness he is going to leave behind is important to the future track of Laura though. Such a complex set up. I cannot recall something like this scenario.

I am sure no one has used this joke right. Polo!

Honestly, I'm questioning the west turn.

That would be a flooding nightmare up and down the entire coastline.

Marco is spinning up some tornadoes in the ocean. It’ll be interesting to see if we can get any on land today.

That'll teach me (again) to not watch the convection and instead pay attention to the CoC positioning at night though. Last night I was obviously watching the convection and making assumptions based on that - once the sun came up and one could see where the CoC was, the path made a lot more sense. I know better.

Wondering now if New Orleans will even see rain off this. With all the convection being sheared off to the NE, this has turned into a FL panhandle rain event. Seems to be having a tough time getting anything going west of the Alabama coast at all.

They will as it the mid level energy begins getting shunted west with the ridge building in.

Hi all. Based on my limited science knowledge, I’m wonder about the western turn. Right now Biloxi, MS has the lowest barometric pressure here on the Gulf Coast. Won’t that be where Marco heads??

I guess those people do not understand Turn Around Don't Drown. Lets drive through the large surf that sounds like fun.

That's part of it - TCs do tend to head towards lowest pressure, but they are also very much subject to mid-level steering winds. So yes - it will pull that way and west as the mid level winds push in.

The center of Marco just made landfall at the mouth of the Mississippi River.

Super tropical airmass and deep overcast with periods of rain and very low LLCs as a result of Marco's mid level remnants. Neat stuff .

 

[Blountwolf]

Nothing left of Marco the last remnant of the swirl is now just a bump in Laura's NW wind field. Amazing.
