The storm had maximum sustained winds of about 60 miles per hour Monday morning with stronger gusts but was expected to get stronger tonight.
There were no coastal storm watches or warnings issued early Sunday and the storm was expected to meander off the Carolinas for the next few days.
Many North Carolina beaches were closed to swimming on Monday due to heavy surf and unsafe rip currents, according to a statement from the governor's office.
The second named storm of this year's hurricane season is now "meandering" off the Carolinas, says an advisory issued early Monday morning by the US hurricane centre. Winds within the disturbance range between 28 to 34 miles per hour.
Beryl was named the first hurricane of the Atlantic season Friday.
More than nine months after Hurricane Maria, about 1,500 people in Puerto Rico are without power on the island; about 60,000 have only tarps for roofs.
Forecasters said Beryl probably would dissipate once it moved south of Haiti and the Dominican Republic on Tuesday or Wednesday.
Haligonians could feel the impacts of a tropical storm later this week that has developed off the East Coast of the United States.
Puerto Rico Governor Ricardo Rossello met with his Cabinet and weather experts on Sunday to prepare for Beryl's arrival, Rossello's office said in a statement.
Before the storms arrived, forecasters warned residents in Puerto Rico and the U.S. Virgin Islands that flooding was likely due to the torrential downpours.
The Tropical Storm Watch for Barbados has therefore been discontinued.
