A grandmother and her teenage son were rescued from the water in Charlestown on Thursday.
The deputy chief of the local ambulance service rescued a 62-year-old woman and her teenage grandson when they got caught in the high surf.
The deputy chief, Jordan Dolock, says he was further east down the coast near Blue Shutters Beach when he happened to see a 6-foot wave crash onto shore and knock the woman down.
Dolock said the woman was unable to stand due to additional waves. He said her grandson entered the water after her, but became a victim of the surf.
The victims were transported to Westerly Hospital where they were treated for near-drowning symptoms.
The National Weather Service canceled a high surf advisory for the Rhode Island shore Friday morning.
