Showers were very numerous, with rainfall accumulations surpassing 8 inches in sectors of northeastern and southeastern Puerto Rico. Soils were saturated, and rivers were running very high, triggering the issuance of a Flood Watch. With the excessive rainfall, multiple flash flooding events and mudslides unfolded.
