The LLC is becoming better defined at every frame. In the convection is trying to form over it. I expect this maybe taking a run at tropical storm.

Yes there is convection over the low but let's see if it persists.

During the afternoon hours, the low-level vortex that I mentioned earlier near 15N has become MUCH better defined (It appears to have closed since this morning when it appeared quite open.). This will only mean that the tropical depression will probably remain as a tropical cyclone for the time being.
Convection has been building during the afternoon, which has caused the LLC to tighten up. Any further increase in deep convection over the low will cause an upgrade to tropical storm status. In any case, if it becomes a tropical storm, it should be a very weak storm due to unfavorable conditions ahead of it.
I certainly don't expect an upgrade at 11 pm. If it were to be upgraded, it would certainly be during the day tomorrow, once/IF convection persists over the low and is not pushed away due to the fairly unfavorable upper-level winds...
