ATL: MARCO - Remnants - Discussion

[galvestontx]

What is going on with Marco and Laura's NHC's track? They seem to be intersecting in the same Wed/Thur timeframe around the Louisiana/Texas coast???

Are they going to merge somehow and will Marco cause increase shear for Laura or will Laura obliterate what is left of Marco's remnants? Strange situation.

Marco will likely be long-gone by the time Laura arrives. The low-level cloud swirl should be tracing southward along the mid TX coast as Laura approaches. Laura won't even know it's there.

So do you think Laura is a Texas storm or Louisiana storm?

Sure getting a lot of mixed signals from the board today.

You think this mixed, Marco is under strong sw shear, yet the convection is in the southern half circle? Who knew?

I would never ever prematurely bury any tropical
system in GOM in later August but hey that’s just
my opinion.

Marco continues on a due north trajectory which proves it isn’t weakening yet as it is following the steering of a stronger system. I see no obvious signs of destructive shear. In fact, the upper level winds seem beneficial for the time being as it is ventilating the storm nicely. I imagine it will end up being too much for Marco, but one more nice burst of convection could sustain a hurricane until landfall.

That due north motion is likely the MCL. Surface center is still likely moving NNW....so it appears to be decoupling. Will know more with next recon fix.....MGC

Not sure that applies here either. There is nice outflow in all quadrants. Marco might be slightly weaker but it’s mainly due to lack of strong convection, IMO.

Extrap. Sfc. Press: 996.7 mb (29.44 inHg) this thing is more like a giant TOR than a TC. And it is right in the convection.

You can't say the guys not a fighter two serious hot towers.

Well northeast of its last estimated position. That is if that is the center.

[supercane4867]

Recon indicates Marco is probably no longer a hurricane.

[xironman]

I can't remember a position where Marco was west of where predicted.

[tropicwatch]

Based on the latest forecast cone, the HH should find a westward component to Marco's movement during this mission.

Didn’t go through the NE quad yet, but I wouldn’t be surprised.

Based on the latest forecast cone, the HH should find a westward component to Marco's movement during this mission.

They ‘should’, but it has already gone way off the cone from 3 hours ago. Like I said earlier, Mississippi coast better not sleep on this just yet.

The +9 mbar pressure rise is enough to confirm Marco has weakened below hurricane status.

I’ve been watching Laura this whole time... might’ve been watching the wrong one
