Event narrative

Broadcast media reported that the police had to close Expreso Martinez Nadal due to significant flooding.

Wider weather episode

The combination of an approaching trough, increasing moisture from the Caribbean, a light southeast wind flow and local effects resulted in several active days across Puerto Rico. These factors enhanced the afternoon showers and thunderstorms for a few days. Additionally, the soils remained saturated from the rains in September, so several mudslides and flooding reports were received.
