Hurricane Irma, with its 110 mph winds, posed no imminent threat to land Saturday as it drifted across the Atlantic Ocean.
The National Weather Service warned the Category 2 storm was likely to pick up speed and strength when it reaches the Caribbean Sea in the coming days, although it was too soon to say if Irma will reach the United States.
The storm was moving northwest at 15 mph, and could possibly affect the eastern end of Puerto Rico by Thursday morning.
Forecasters have not issued coastal watches or warnings for Irma.
Irma comes on the heels of the destructive Hurricane Harvey, which devolved into a tropical storm after pummelling the Texas coast with deadly flooding. Harvey was responsible for at least 44 deaths.
