There is a large area of convection behind TD 17 that seems to be splitting off from TD 17 and forming a new tropical wave. It has a good amount of convection on infra-red imagery.

Here it is (showing up faintly) on visible imagery.

Since it is following TD 17, it may have a possibility to become an INVEST as well. Although a system might disappear if it is too close to another system, in some cases a mutual benefit is established so both systems develop. An example is what is going on with Hurricane Jova and Hurricane Kenneth in the east-central Pacific right now. They are very close but are strengthening.
Any thoughts?

Here is more information on the wave from the National Hurricane Center's 8:05PM Tropical Weather Discussion tonight.
EAST ATLANTIC TROPICAL WAVE ALONG 27W/28W S OF 17N MOVING W 10
KT. THE LAST FEW VISIBLE MET-8 IMAGES OF THE DAY SHOW A LOW
AMPLITUDE BUT WELL-DEFINED AND SHARP SIGNATURE ABOUT 200-250 NM
SW OF THE CAPE VERDE ISLANDS. THERE MAY BE A WEAK LOW ALONG THE
WAVE BUT WHATEVER LOW-LEVEL CIRCULATION THERE MAY BE APPEARS
STRETCHED FROM SW TO NE. SCATTERED MODERATE/STRONG CONVECTION IS
MAINLY AHEAD OF THE WAVE NEAR THE ITCZ FROM 4N-10N BETWEEN
27W-34W. WIDELY SCATTERED SHOWERS/TSTMS ELSEWHERE FROM 7N-16N
BETWEEN 22W-28W.

Agreed... it is looking pretty good currently. I think that - especially if it keeps it up - this may very likely become yet another INVEST and something to watch down the road behind INVEST.95L.

The wave has weakened, but a new wave has just exited the coast of Africa with good convection.

EAST ATLANTIC TROPICAL WAVE TILTED FROM 7N29W TO 18N32W...WITH A
1009 MB LOW NEAR 10N30W...MOVING W 10 KT. THE WAVE CONTINUES TO
DISPLAY A SHARP LOW-LEVEL SIGNATURE WITH CONVERGENCE MAXIMIZED
ALONG THE NRN END OF THE AXIS. THE LOW APPEARS TO BE EMBEDDED
WITHIN THE ITCZ AND WITHIN A RELATIVE VOID OF DEEP CONVECTION.
SCATTERED MODERATE CONVECTION FROM 14N-18N BETWEEN 28W-32W.
SCATTERED MODERATE FROM 8N-12N BETWEEN 32W-37W.
The above from 8 Pm Discussion from NHC.
CapeVerdeWave here is your system with a low.
