More than three months have passed since Hurricane Maria's 155-mph winds plowed through Puerto Rico leaving the island severely crippled and desperate for help.
The storm — which knocked out all power and most cell phone service — was the worst disaster to ever hit the Caribbean island, home to 3.4 million American citizens.
The island is back to some semblance of normalcy . But hundreds of thousands have fled as the conditions fail to improve. More than a third of the island still has no power, and federal workers are still sending food and water supplies to some towns.
Here are five important things to know about Puerto Rico 100 days after Maria:
1) Electricity probably won't be entirely restored before May
The single biggest problem facing Puerto Rico is still the lack of power. Gov. Ricardo Rosselló promised that 95 percent of the island would have power by now. Only 65 percent does.
On Thursday, protests broke out across the island, in towns such as Trujillo Alto and Aquas Buenas, which have not had any power since the hurricane.
The blackout is now the largest in US history. Just take a look at this chart published by the research firm Rhodium Group:
