Read the latest with Friday’s live updates on Hurricane Irma.

A hurricane watch was issued for Antigua and Barbuda on Thursday as a potentially powerful new storm, Jose, brewed in the Atlantic Ocean just one day after part of the dual-island Caribbean nation was devastated by Hurricane Irma.

Hurricane Irma slammed into Barbuda, the less populated sister island of Antigua, leaving an estimated half of its population homeless and killing at least one person, according to the country’s prime minister, Gaston Browne.

The National Hurricane Center, part of the National Oceanic and Atmospheric Administration in the United States, said Hurricane Jose now threatened to make the island nation’s problems worse, kicking the surf into menacing swells and dumping as much as 10 inches of rain that “will maintain any ongoing flooding and may cause additional life-threatening flooding.”

The hurricane watch was issued by both the National Hurricane Center and the National Office of Disaster Services in Antigua.
