Hurricane Maria's impact was like "experiencing the end of the world" and Fiona has unleashed "hell." It's only expected to get worse.

Armando Perez and his 81-year-old mother survived Hurricane Maria when it hit Puerto Rico in 2017. Five years later, they just witnessed Hurricane Fiona, a categorically less intense storm but one that disrupted their lives nonetheless.

Perez's mother, Carmen, has advanced Parkinson's disease and dementia and has been bedridden since June. The two live together in the town of Dorado, and Perez bathes and feeds his mother and changes her diapers. 

But since Fiona hit the island five days ago, they've been without power or clean public water. And triple-digit temperatures are baking their home's concrete walls, turning Carmen's room into "a furnace" in the afternoon.
