Flood · Puerto Rico

Emergency management reported that Ramn Luis Rivera Avenue, near a Walgreens pharmacy, was flooded but passable due to poor drainage. The report did not include whether any vehicles were stranded.

Lingering moisture and marginal instability associated with a nearby upper-level low to the northwest, combined with breezy east-southeast low-level winds, led to isolated to scattered showers over eastern Puerto Rico early in the morning. As the day progressed, showers and cloudiness spread across much of Puerto Rico, with more frequent and intense showers and isolated thunderstorms developing over the San Juan metropolitan area (particularly over Bayamon, Catano and Toa Baja where flooding and flash flooding reports were received) and parts of north-central to northwestern Puerto Rico during the afternoon. Rainfall totals of up to four inches prompted Flood Advisories and Flash Flood Warnings in the San Juan metro area.
