Multiple Marine Weather Alerts, Coastal Flood Advisory Issued

Multiple marine weather alerts have been issued by the National Weather Service for portions of the USVI and Puerto Rico due to another powerful swell and ongoing breezy conditions.  

“Marine and coastal conditions will deteriorate even further by tomorrow due to another northerly swell. Small Craft Advisories, Coastal Flood Advisories, High Surf Advisories, and a High Risk of Rip Currents will be in effect by tomorrow due to building seas and hazardous breaking waves,” according to an update on Wednesday night from the NWS in San Juan, Puerto Rico.

“A Coastal Flood Advisory will be in effect tomorrow for most of the Atlantic Coastline of Puerto Rico (breaking waves from 14 to 18 feet), Culebra, and the northern USVI (breaking waves from 10 to 14 feet). Flooding of lots, parks, and roads with only isolated road closures are expected. Dangerous swimming and surfing conditions and localized beach erosion are also expected,” the NWS update continues.

The following marine weather alerts are listed in local Atlantic Standard Time.  

A “Coastal Flood Advisory” will go into effect for portions of the USVI and Puerto Rico at 6 a.m. on Thursday and last until at least 6 p.m. on Friday. 

A “High Surf Advisory” will go into effect at 6 a.m. on Thursday and last until at least 6 a.m. on Saturday. 

A “Small Craft Advisory” will go into effect from 2 a.m. on Thursday and last until at least 8 a.m. on Sunday.

The risk for rip currents can become elevated during powerful swell events. A recent interview by the Source with Ernesto Morales, a warning coordination meteorologist at the NWS in San Juan, PR, offers information about rip current safety.

The Source Weather Page will be updated regularly to reflect the most recent weather alerts.
