Showers and isolated thunderstorms are expected to develop across western Puerto Rico this afternoon, driven by daytime heating and moisture from an induced surface trough approaching the islands, according to the NWS.
Some showers may produce moderate to heavy rainfall, leading to urban and small stream flooding, especially in low-lying and poor-drainage areas, the NWS said.
Conditions will gradually improve this weekend, but a moderate risk of rip currents will remain, according to the NWS.
