Puerto Rico may be without power for months after Hurricane Maria hit the U.S. territory with powerful winds that downed trees, ripped the roofs off homes and turned roads into rivers with flash flooding.

Gov. Ricardo Rosselló told CNN late Wednesday night that it may take months to restore power to the entire island.

He said that as a result of the powerful Category 4 hurricane, no one on the island has power from utilities since the power grid is ‘a little bit old, mishandled and weak’.

‘It depends on the damage to the infrastructure,’ Rosselló said. ‘I’m afraid it’s probably going to be severe. If it is … we’re looking at months as opposed to weeks or days.’

The exact impact of Maria won’t be realized until authorities can do a flyover on the island to see what remains and what has exactly been destroyed. Rosselló said that if transmission lines are in better condition than thought, than power outages could be fixed sooner.

Rosselló also said that at least one person was killed in the storm on the island when a board was ripped from a house it had been nailed to and hit a man. He said that the number of deaths could increase in the next few days.

‘We still don’t have a lot of information,’ he said. ‘We’re virtually disconnected in terms of communications with the southeast part of the island.’

More than 10,000 remained in shelters Wednesday night as the governor has imposed a curfew on the island from 6pm to 6am beginning Wednesday and ending on Saturday morning.

Search and rescue teams began taking to the streets of Puerto Rico, which has a population of 3.3million people, after the storm weakened to a Category 2 and heads for the Dominican Republic.

The storm has battered Puerto Rico for most of Wednesday before moving on towards the Dominican Republic
