Between September 19-21, 2017, Hurricane Maria devastated the entire island of Puerto Rico and caused a major humanitarian crisis. Originally as a powerful Category 5 hurricane, Maria was the strongest storm to impact the island in nearly 90 years. Maria made landfall on Puerto Rico on September 20 as a high-end Category 4 storm, bringing a large storm surge, very heavy rains, and wind gusts well above 100 mph (160 km/h). It flattened neighborhoods, crippled the island's power grid, and caused an estimated 2,982 fatalities and US$90 billion in damage.
