Heavy Rain Forecast for Puerto Rico and U.S. Virgin Islands this Week

Heavy rain with flooding is possible across portions of Puerto Rico and the USVI during the middle of the week. Seas are also forecast to become hazardous.

The potential incoming precipitation is associated with a trough (an extended region) of low pressure that is predicted to move off the southeast of the U.S. mainland. As the trough passes across the USVI and Puerto Rico, moisture to the south is expected to be drawn up and over the islands.

“A deep layered trough and accompanying frontal boundary will approach the islands by late Monday into Tuesday, pulling moisture from the south into the local islands,” according to an update on Sunday from the National Weather Service in San Juan, Puerto Rico.

“This will increase the risk for flooding, rapid river rises, and mudslides across Puerto Rico and in the U.S. Virgin Islands,” the NWS update continued.
