Hurricane Irma, one of the most powerful Atlantic storms in a century, churned across northern Caribbean islands on Wednesday with a potentially catastrophic mix of fierce winds, surf and rain, en route to a possible Florida landfall at the weekend. Irma is expected to become the second powerful storm to thrash the U.S. mainland in as many weeks but its precise trajectory remained uncertain. Hurricane Harvey killed more than 60 people and caused damaged estimated as high as $180 billion when it hit Texas late last month. The eye of Irma, a Category 5 storm packing winds of 185 miles per hour (295 km per hour), moved away from the island of Barbuda and toward the island of St. Martin, east of Puerto Rico, early on Wednesday, the U.S. National Hurricane Center (NHC) in Miami reported.
