It's a term you would use to describe a storm that formed in the Western North Atlantic, kinda closer to land. Usually either a cut off low or a Tropical wave interacting with a cutoff low, shortwave or other bit of energy. Usually something not 100% African wave.
Charley for example..TD just east of the islands. All Tropical wave straight from Africa. I wouldn't call it homegrown either. They are mostly born in SW or W Caribbean, GOM, Bahamas or along the east coast.

90% of tropical cyclones develop from tropical waves that move off the coast of Africa. That does not make them a Cape Verde system.
The official definition of a Cape Verde tropical cyclone is one that develops near the Cape Verde Islands, or within 800 miles (if I remember correctly). Taking a look at Charley's path, it developed outside of that.
I guess you could not consider it a Cape-Verde type nor a homegrown type.

...MID SOUTH/CENTRAL GULF COAST REGION...
DESPITE WEAK/UNFOCUSED ASCENT...DAYTIME HEATING OF A MOIST BOUNDARY
LAYER WILL CONTRIBUTE TO THE DEVELOPMENT OF 1000 TO 1500 J/KG
MIXED-LAYER CAPE...SUPPORTING SUBSEQUENT INITIATION OF SCATTERED TO
ISOLATED AFTERNOON SHOWERS AND THUNDERSTORMS. GIVEN THE DEGREE OF
CAPE AND DEEP-LAYER SHEAR 30 TO 40 KT EXPECTED...A FEW
STRONGER/ORGANIZED STORMS COULD EVOLVE...CAPABLE OF PRODUCING GUSTY
WINDS AND HAIL.
LACK OF A LOW-LEVEL FOCUS AND THUS THE EXPECTATION OF LIMITED STORM
COVERAGE PRECLUDES UPGRADE TO SLIGHT RISK ATTM. SHOULD POTENTIAL
FOR MORE WIDESPREAD STORMS BECOME EVIDENT...UPGRADE MAY BE NEEDED IN
SUBSEQUENT OUTLOOKS.

Here come the bugs and the pollen. My house is already beseiged by hundreds of bees around our bushes. Those disappering honeybees seem to be back. Im a goner
Unreal! We could be in full summer mode come May.
Good morning guys....looking as if we will have neutral condition through out the hurricane season
maybe, but your ridge of warmth may come crashing down into a week:
I'm hoping for a good season as well
That's in 372 hours and the model has shown no consistency. Ignore that.
Indeed. It's starting to appear less likely that this year will be a significant El Nino year, rather a warm neutral one.
I don't like anybody should have thought it would end up a significant El Nino year to begin with. These changes are not rapid, just gradual.
Agreed
Thank GOD there's no such things as normal.
These temp anomalies are unbelievable for this time of the year
Yikes...
Yeah, it's a waiting game
I think it's about time for me to crank out my March hurricane season predictions.
Agreed
