As of right now we aren't expecting any tropical development within the next 48 hours.
There is an upper level low pressure system in the eastern Gulf of Mexico that is bringing extra shower activity to the southern Florida Peninsula. Bahamas, and the FL straights.
There is also a tropical wave that is approaching the lesser Antilles and eastern Caribbean. This will bring increased rain chances to the area for the next 36 hours and rain to Puerto Rico and Hispianola for the weekend.
