According to the Miami NHC, the planned trajectory will pass the system this morning over Dominica, during the day south of St-Kitts and then overnight over the Virgin Islands and Puerto Rico.
The minimum central pressure is estimated at 1007 mb. Maximum sustained winds are near 65 km / h, gusting to 80 km / h. Some strengthening is expected over the next 24 hours and the system, if it isn't already when you read this, should become Tropical Storm Isaias.
