Admittedly, that's not a very high bar to cross.

The ULL over the Mexican desert is taking over and firing convection quickly.
Two big sinks for ventilation - poleward and equatorward outflow channels.
Very rarely see this in the Atlantic.
Pretty much a WPAC characteristic.


What does this mean for this storm? Sorry I’m a newbie to all of this.


Good chance for a much stronger storm than currently anticipated.

Long loop.

convection wrapping around. almost certainly a core in the process of building up.

the big convective pop is coming soon .. only a matter of time .

The upper level outflow is probably the most impressive I've seen for a TD. Really shows that there is essentially no shear over the centre of the depression. We're lucky that the system is so broad and will take time to tighten up, because the environment it finds itself in is pretty favourable for strengthening.

Just beautiful outflow in all directions thanks to a great UL environment.

This storm definitely has "that look" on geostationary satellite imagery. Looking forward to getting some 3D radar observations from the NOAA P3 flight tonight.

Yes, GCANE, this chart plus your other recent comments about outflow are on the money. You can see the outflow developing rapidly in almost all quadrants now if you watch the visible loops. It's that upper level venting with no inhibition at the lower levels plus good mid-level RH that will get this ramping really fast tonight. RI is quite possible. Hurricane is quite possible now.

Yes, since yesterday afternoon it has slowed down, it still has a good 44 hrs left over water before making landfall early Sat afternoon, according to the latest NHC forecast track.
