Even if 97L doesn't develop within the MDR (not suggesting it won't), I wouldn't rule out a scenario like Gert 2017, where it develops when approaching or past the islands. The timing is very similar, too.

A track further west than Gert would make it even more concerning for possible CONUS impacts.

Tropical Weather Outlook
NWS National Hurricane Center Miami FL
800 PM EDT Mon Aug 8 2022

For the North Atlantic...Caribbean Sea and the Gulf of Mexico:

1. Eastern Tropical Atlantic:
A tropical wave continues to produce a large area of disorganized
showers and thunderstorms over the eastern tropical Atlantic a few
hundred miles south-southwest of the Cabo Verde Islands. Gradual
development of this system is possible and a tropical depression
could form by the middle or latter portion of the week before
environmental conditions become less favorable by this weekend.
This system is expected to move westward to west-northwestward at 15
to 20 mph across the tropical Atlantic during the next several days.
* Formation chance through 48 hours...low...20 percent.
* Formation chance through 5 days...medium...40 percent.

97L moving swiftly across the ocean, will that limit any potential development somewhat?

Agree, 97L’s narrative will be if the LLC slows down and stops racing ahead of its convection it could develop. It’s climo for early August. JMHO

Invest 97L is very disorganized this morning. Mid level center and low level center are not staked one bit…this still has a lonngggg ways to go until it becomes a tropical cyclone, if at all.

NHC 8am position was 12.0N/27.5W, not much rotation there IMO, broad circulation near10.5N/30.4W.

Not looking to good for 97L, but there seems to be more going on farther WSW from the area they are tracking. JMHO

Yeah probably not much of a chance this develops but we may need to watch it anyways as it moves further west. Probably unlikely though.

I am in no way a professional. Take what I say with a grain of salt as I could be totally wrong. Please refer to the NHC, NWS, or SPC for official information.

At 2pm the NHC says 12.0N/27.5W, but there is a nice circulation with convection popping near 10.6N/31W.

Yep. Gert failed to develop in the MDR, but found more favorable conditions further west. I don't remember models really showing much happening until Gert started organizing near the Turks and Caicos Islands. I believe Gert is also the storm the GFS refused to show even though it was a cyclone.

18z TWD:

An eastern Atlantic tropical wave is west of the Cabo Verde
Islands near 27W from 20N southward through a 1010 mb low at
12N27W, and moving west around 15 kt. Scattered moderate
convection is occurring from 08N to 15N between 25W and 32W.
Some gradual development of this system is possible and there is a
slight chance that a tropical depression could form over the next
couple of days. Afterward, environmental conditions will become
less favorable.
