Officials in Puerto Rico say power has been restored to 98.8% of customers after an island-wide blackout hit the U.S. territory earlier this week.

The island of Puerto Rico is suffering another islandwide power outage, just months after a dayslong blackout on New Year's Eve kept residents in the dark. Luma Energy said the complete interruption to its service began at about 12:40 p.m. Wednesday. That means all 1.4 million customers on the island were without power.

More than 400,000 Puerto Ricans left without water service as power company scrambles to restore critical facilities.
