What the National Weather Service wrote

A rapid water surge caused flooding across PR-936 in Quebrada Honda, overtopping a bridge and rendering the roadway impassable. A vehicle was swept from the roadway by the floodwaters while attempting to cross the bridge. Local emergency management personnel rescued the occupant, and no injuries were reported. The road remained closed after the event due to continued hazardous flooding conditions.

The wider storm

An amplifying mid- to upper-level trough, combined with above-normal moisture, maintained an unstable, wet pattern. With previous rain left saturated soils and elevated rivers, heavy rainfall quickly lead to urban flooding, small stream flooding, river flooding, landslides and flash flooding. Significant flooding occurred in Las Piedras, particularly, where several houses where flooded and flash flooded following heavy rainfall.
