St. Croix has gotten the most rain so far, with a narrow region of its SW coast showing Doppler estimates of 4-6" of rain, though most of the island is showing around 2". There is a large region over open water that has seen 10-11"+ of rainfall 55-80 miles SSE of Puerto Rico and 45-60 miles SW of St. Croix. St. Croix is under a flash flood warning.

System looks fairly good on radar, still has a lot of development to do, but it's quite small. Question is, with its proximity to the mountains of Puerto Rico, whether this will disrupt its development at all.
