Hurricane Maria slammed into Puerto Rico in the early hours of Sept. 20, bringing 155 mph winds that knocked the majority of the 3,500-square-mile island into one of its longest widespread power outages since Hurricane Jeanne made landfall in 2004.

More than 60 people have died since the storm hit. However, reports suggest the actual death toll might be more than 1,000.

Officials warned the storm’s destructive blow to Puerto Rico’s aging electrical infrastructure could take months to repair.

Two months after Maria made landfall on Sept. 20, the majority of the island’s 3.4 million people were still without power. On Nov. 28, the Department of Energy reported, for the first time, that more than half of normal peak load electricity was restored. Residents have relied on portable generators as workers across the island try to repair the damaged electrical grid.

In the days after Maria, many residents struggled to access gasoline, food, water, money and a cellphone signal to contact family members.

Others, especially those without electricity, have been cut off from the outside world.

In the island’s mountainous regions, massive landslides prevented local and federal assistance from reaching residents for more than a week.
