Puerto Rico barely had a minute to recover from being grazed by Hurricane Irma when Maria approached the island.

Maria was one of the strongest and most powerful storms ever recorded in the Caribbean; her eye spanned the entire Puerto Rican territory.

With wind gusts of 150 mph, the storm left massive flooding across Puerto Rico.

The island lost its entire electricity supply.

Puerto Rico is still in a state of acute emergency: Residents are trapped in sweltering high-rise buildings; hospitals cannot safely store medicines that need to be kept cold; 70,000 residents in the northwest of the island have been ordered to evacuate because the Guajataca Dam is on the verge of collapse, threatening to unleash more flooding, Reuters reports.

Nearly all cell phone towers are still out of commission, CNN noted.
