Tropical Storm Sam has formed in the eastern Atlantic Ocean and is anticipated to strengthen into Hurricane Sam by Friday, the U.S. National Hurricane Center (NHC) announced on Thursday.
The system is moving west at about 16 mph and is packing maximum sustained winds of 50 mph, it added.
The weather agency said the motion of Sam is expected to continue going westward over the next several days, and then the storm will gradually slow down.
There are no coastal watches or warnings in effect at the time as it is currently unclear if Sam will pose a threat to the United States.
It is likely Sam could generate high surf and rip currents along the U.S. East Coast more than a week from now even if it stays well offshore, the network reported.
Sam is currently the only active storm in the Atlantic as Rose and Peter weakened to tropical depressions and could further degenerate into a remnant low by Friday, the NHC said in its latest advisory.
