The National Hurricane Center is tracking two weather systems in the Atlantic Ocean – neither of which pose immediate risk to the United States – while Henriette and Ivo wax and wane in the Pacific Ocean.

National Hurricane Center meteorologists warned of life-threatening impacts as the storm is expected to strengthen.

Ivo was a tropical storm in the North Pacific Ocean Sunday afternoon Eastern time, the National Hurricane Center said in its latest advisory. Ivo is the ninth named storm to form in the Eastern Pacific in 2025.
