Now that Hurricane Maria has moved past Puerto Rico, search and rescue teams are taking to the darkened streets of an island almost completely without power.
The devastating winds had died down to a whisper late Wednesday and the flooding rains were just a drizzle, but getting around was difficult due to widespread damage and no electricity except from generators.
"We are 100% without power," a spokesman for the Puerto Rico governor's office said Wednesday.
The storm caused widespread flooding and ripped trees out of the ground. More than 10,000 remained in shelters Wednesday night.
"This is total devastation," said Carlos Mercader, a spokesman for Puerto Rico's governor. "Puerto Rico, in terms of the infrastructure, will not be the same. ... This is something of historic proportions."
A nightly curfew from 6 p.m. to 6 a.m. will take effect Wednesday evening and end Saturday morning, Puerto Rico Gov. Ricardo Rosselló announced.
There were no immediate reports of injuries in Puerto Rico, a US territory with 3.3 million people
Maria weakened to a Category 2 hurricane Wednesday afternoon, with winds of 110 mph, but is expected to gain strength with the core back over warm water.
Maria is next expected to pass by the Dominican Republic and the Turks and Caicos Islands, causing dangerous storm surge and rainfall.
The once-major hurricane has already killed seven people on the Caribbean island nation of Dominica, said Gaston Browne, the Prime Minister of Antigua and Barbuda.
Browne said he had been communicating with the Prime Minister of Dominica, Roosevelt Skerrit, who reported "widespread devastation" and whose own house was shredded by the storm.
Puerto Rican Olympic gymnast Tommy Ramos, who was riding out the storm in the northern city of Vega Baja, posted video of gusts blowing debris in front of him.
"The house is steady," Ramos told CNN. "What scares us is the flooding."
Astriv Velez, who survived the storm inside a walk-in closet, said water was coming in through the walls of her home in Trujillo Alto, just outside San Juan.
"The wind and rain has not stopped," Velez said. "There are no trees, there is no green -- only brown."
She said she's worried about whether a dam near her home will hold up. "It will be very catastrophic if that dam breaks," she said.
Devastation in St. Croix and St. Thomas
Maria obliterated homes on several other Caribbean islands.
Aaliyah Bisamber of St. Croix shot video of Maria's annihilation of her old house, which was right next to her new home.
"I was pretty amazed the hurricane had such power to rip off half the house," she told CNN.
Murillo Melo recently moved to St. Croix from Brazil -- only to face one of the island's most catastrophic hurricanes.
"It was really scary. The floors were shaking, the walls, everything was moving and shaking," he said.
"Here on the island and on the mainland people are trying to get in contact with friends and relatives. ... People are desperate to get some news from their friends and relatives."
US Coast Guard Commandant Adm. Paul Zukunft said the damage to St. Croix is especially alarming.
"First priority is going to be saving of lives -- not just in Puerto Rico, US Virgin Islands -- I'm especially concerned with St. Croix, that was also in the path of Hurricane Maria when it was a Category 5 hurricane," Zukunft said Wednesday.
On the US Virgin Island of St. Thomas, retired New York police detective Austin Fields surveyed the damage to his home.
"My home is no longer a home," he said.
On Dominica, which Maria smashed earlier this week, the devastation is immense, a CNN crew flying over the island reported. Hundreds of homes have been visibly flattened or damaged. Many had roofs torn off.
The landscape has been stripped bare. Thousands of trees have been snapped at their base and those still standing devoid of leaves. Dominica was a lush green landscape, including rainforests, but now is brown and lifeless.
Virgin Islands and Dominican Republic under the gun
Maria's wrath is far from over.
A hurricane warning is in effect for the Turks and Caicos, the southeastern Bahamas and parts of the Dominican Republic, where strong winds are expected to hit Wednesday night, forecasters said.
Dangerous storm surges "accompanied by large and destructive waves" will raise water levels 10 to 15 feet above normal tide levels in the hurricane warning areas of the southeastern Bahamas and the Turks and Caicos, the hurricane center said. The islands could also see as much as 20 inches of rain.
Long-range models say Maria could move toward the North Carolina coast as it moves north. CNN Meteorologist Tom Sater said people should keep an eye on the storm.
'First responders cannot go out there'
Maria became the first hurricane of Category 4 strength or higher in 85 years to make a direct landfall on Puerto Rico.
The hurricane slammed the US territory with such intensity, it broke two National Weather Service radars there.
Calls for rescue immediately started pouring in -- but to no avail.
"First responders cannot go out there," Mercader said, echoing the governor's earlier warning that emergency crews wouldn't go outside in winds stronger than 50 mph.
