Hurricane Maria was the rainiest storm known to have hit Puerto Rico, and climate change is partly to blame, according to a new study.
The worst rain fell in the mountainous central part of Puerto Rico, from the northwest to the southeast. That part of the island is rainy under normal conditions. In an average year, it gets more than 150 inches of rain.
When Maria hit in 2017, it dropped nearly a quarter of that annual rainfall in just one day.
