Radar would seem to indicate that the majority of the convective activity is on the southern side of the envelope. Interacation with PR is likely inhibiting much development taking place to the north of the island. This will likely remain the same as the disturbance approaches the DR and Haiti. With surface reports and radar suggesting that if there is a COC it is to the west or west-southwest of PR, then the chance for development is likely to be shortlived in the near term as this centre would be tracking across the terrain of Hispaniola. The other possibility of course is for a COC to form elsewhere within the larger envelope - entirely possible as the system is still in its formative stages.
