Wider weather episode

Puerto Rico observed two events with above-normal moisture and instability from May 3rd through the 9th. The weather scenario for May 3rd involved an upper-level trough and an induced surface trough with deep moisture from the Caribbean, which enhanced thunderstorms and downpours across most of PR. Besides those atmospheric conditions, it is essential to highlight that April ended up being one of the wettest periods for any other end of the month since we have historical records. The USGS river streamflow stations reported that most of the eastern half of the rivers had streamflows from above-normal to much above-normal ahead of the event. This situation triggered a Flood Watch that was issued for the islands from Friday through Sunday.
