Many more factors are going for this! Don't look away for a second this time of the year
For it!
1# Low wind shear
2# Upper level high
3# Warm ocean waters
4# Already showing that it may have a low pressure near the surface.(Quickscats not all there. But doe's show curving on what it doe's show.)
5# Its late July!
Against it
1# A little dry air.
So this very well could be a pulse down then up kind of system. We need to keep watching it.

Here's what the TPC had to say about the dry air in their 8:05 TWD:
CARIBBEAN...
A NARROW/WEAK MID-UPPER TROUGH EXTENDS ACROSS THE CENTRAL CARIBBEAN FROM PUERTO RICO WSW TO A RETROGRADING UPPER LOW OVER NICARAGUA NEAR
13N86W. THE UPPER LOW AND THE TROPICAL WAVE ARE AIDING SHOWERS/ THUNDERSTORMS OVER ALL OF CENTRAL AMERICA. THE STRONGEST BEING IN THE GULF OF HONDURAS AND OVER LAKE MARACAIBO. MODERATE SUBSIDENCE/
VERY DRY LOWER LEVEL AIR DOMINATES THE AREA FROM 12N-18N BETWEEN 64W-85W LIMITING SIGNIFICANT CONVECTION. HOWEVER...LOWER LEVEL MOISTURE IS RETURNING OVER THE E CARIBBEAN AS THE NEXT TROPICAL WAVE MOVES W ACROSS THE CARIBBEAN. AT THE SURFACE...THE S MIGRATION OF THE ATLC SUBTROPICAL RIDGE IS CAUSING SURFACE PRESSURES OVER THE
CARIBBEAN TO BE ABOVE CLIMATOLOGICAL VALUES FOR THIS CLOSE TO AUGUST.
