Millions of people across Puerto Rico woke up Thursday to a grim new reality.
Hurricane Maria, the most powerful storm to hit the U.S. territory in almost a century, ravaged the island, demolishing homes and knocking out all electricity. It could take half a year to restore power to the nearly 3.5 million people who live there.
The eye of the storm moved offshore overnight, but the danger remained Thursday: Intense flooding was reported, particularly in San Juan, where many residential streets looked like rushing rivers.
The storm has been blamed for the deaths of 18 people, including two in Puerto Rico, but many fear that toll could climb as authorities were beginning to assess the extent of the damage and search for survivors.
