Storm Arthur is forecast to become post-tropical later on Tuesday and dissipate by end of the week, the U.S. National Hurricane Center (NHC) said.
Tropical Storm Arthur is located about 300 miles (485 km) east north-east of Cape Hatteras, North Carolina, packing maximum sustained winds of 60 miles per hour (95 km/h), the NHC said.
"Slight strengthening is possible this morning, but a general weakening trend is expected to begin by Wednesday," the Miami-based weather forecaster said.
Arthur is the first named storm of the 2020 Atlantic hurricane season.
