'We've Never Gone Through This': Hurricane Maria Knocks Out Puerto Rico's Electricity03:47

Updated at 11 p.m. ET

Puerto Rico is trying to start the process of recovering from Hurricane Maria — and it's doing so after the powerful storm blew homes apart, filled roads with water and tore at its infrastructure. Flash floods are persisting, and the island has no electricity service.

"We are without power, the whole island is without power," Jenniffer González-Colón, Puerto Rico's resident commissioner — its representative in Congress — told Morning Edition on Thursday. González-Colón spoke from Carolina, near San Juan.

Maria is beginning to spread over the Turks and Caicos Islands — by Thursday evening, its eye was 90 miles north-northeast of Puerto Plata, Dominican Republic, and 65 miles east-southeast of Grand Turk Island. It was moving northwest at 8 mph, according to the National Hurricane Center. Maria's maximum sustained winds of 125 mph make it a Category 3 hurricane.

The shutdown of Puerto Rico's electrical grid has meant big changes for students like Miguel Santiago, who attends the University of Puerto Rico and works at WRTU.

"We've never gone through this, you know?" Santiago tells NPR's Adhiti Bandlamudi. "We've never gone through so much time — at least my generation has never gone through so much time — without electricity. So ... going through my mind, it's a new life."

Other challenges, Santiago says, range from living under a nightly curfew to getting around debris and wreckage from the storm that ran over the island as a Category 4 hurricane.

On the sidewalks, Santiago says, "every three steps you take, there's another tree on the floor. And not just branches, but trees as a whole. You know, their roots are intact. They fell off completely. It's really hard to walk around it."

Ajit Pai, the chairman of the Federal Communications Commission, said in a statement that 95 percent of the cellphone service was down on the island and that the hurricane "has had a catastrophic impact on Puerto Rico's communications networks." To restore service "will be a challenging process, particularly given the power outages throughout the island."

All of Puerto Rico has been under flood warnings — which were extended by the National Weather Service's San Juan office Thursday as rain from Maria continued to fall.

In many places, Maria ruined repairs that had only just been completed after the island was hit with a glancing blow from the massively powerful Hurricane Irma. Puerto Rico is home to 3.4 million people, and Maria is the strongest storm to hit there in decades.

NPR's Greg Allen reported on the storm's effects for our Newscast unit.

"Maria dropped a record 35 inches of rain in some places. Rivers across the island are out of their banks. Authorities opened the floodgates on reservoirs making flooding worse in some downstream communities. In Levittown, west of San Juan, flooding forced residents to their rooftops where they awaited rescue.

"In the city of Las Piedras, officials say they recorded wind gusts over 200 miles per hour. Maria's high winds took roofs, destroyed homes and snapped concrete power poles in two."

As the storm's intense winds and high storm surge wreaked havoc on Puerto Rico on Wednesday, San Juan Mayor Carmen Yulín Cruz called for help from the mainland U.S., saying, "The Puerto Rico and San Juan we knew yesterday is no longer there."

Speaking to González-Colón on Thursday, NPR's David Greene asked for her impression.

"It is that bad," she said. "I mean, there is devastation. People with wooden houses are no longer there. And all of the forests and palm trees — they're not there. It's bare soil. It is devastating, and I hope we can recover soon."
