Lows will be in the upper 70s to low 80s across lower elevations of the islands, and in the upper 60s to low 70s across higher elevations of Puerto Rico. We anticipate a gradual increase in humidity and, therefore, precipitable water values. This increase is associated with an approaching tropical wave from the east. On Thursday, a low-pressure system located over the western Atlantic will move north of the region. The associated cold front is forecast to deepen and approach the islands, and a prefrontal trough will enhance the potential for another round of convective shower and thunderstorm activity by the end of the workweek. With these weather features across the islands, we forecast minor flooding in urban areas and small streams. Overall, we anticipate warm days with active afternoons and rainy nights through the short-term period.
