PORT-AU-PRINCE, Haiti — Puerto Rico’s governor has declared a state of emergency following heavy rains, widespread flooding and landslides in the U.S. territory. One person has been reported missing.

Gov. Pedro Pierluisi also activated the National Guard on Wednesday to help 22 of the island’s 78 municipalities that were hardest hit by incessant rains.

More than 10 inches (25 centimeters) of rain were reported over two days in Puerto Rico’s interior, with some streets turning into flowing rivers.

Police issued a statement Thursday noting that numerous rivers have broken their banks and that several roads are impassable. They said an unidentified man was swept away by a river in the northwest town of San Sebastián, where several people also were trapped by rising waters, waiting on a roof before they were rescued.

Flooding has also decimated crops across the island.
