Summary
Hurricane Maria was an extremely powerful and catastrophic Category 5 tropical cyclone that devastated the northeastern Caribbean in September 2017, particularly Puerto Rico and Dominica. It was the deadliest and costliest hurricane to strike Puerto Rico, causing an estimated 2,975 deaths and over $91.61 billion in monetary losses, with most of the damage occurring on the island. Maria also resulted in the worst electrical blackout in U.S. history, which lasted for several months. The storm developed on September 16 east of the Lesser Antilles and rapidly intensified, making landfall on Dominica on September 18 as a Category 5 hurricane. After crossing Dominica, it re-intensified to its peak intensity with sustained winds of 175 mph before striking Puerto Rico as a high-end Category 4 hurricane on September 20. The hurricane eventually weakened and dissipated over the open Atlantic by October 2. The name Maria was retired following the 2017 season.

Hurricane Maria was an extremely powerful and catastrophic tropical cyclone that affected the northeastern Caribbean in September 2017, particularly in the U.S. territory of Puerto Rico, which accounted for 2,975 of the 3,059 deaths. It is the deadliest and costliest hurricane to strike the archipelago and island of Puerto Rico, and is the deadliest hurricane to strike the country of Dominica and the territory of the U.S. Virgin Islands. The most intense tropical cyclone worldwide in 2017, Maria was the thirteenth named storm, eighth consecutive hurricane, fourth major hurricane, second Category 5 hurricane, and deadliest storm of the extremely active 2017 Atlantic hurricane season. With over 3,000 deaths and a minimum central pressure of 908 millibars (26.8 inHg), Maria was both the deadliest Atlantic hurricane since Jeanne in 2004, and the eleventh most intense Atlantic hurricane on record, respectively. Total monetary losses are estimated at upwards of $91.61 billion (2017 USD), almost all of which came from Puerto Rico, ranking it as the fourth-costliest tropical cyclone on record. Maria developed from a tropical wave on September 16 east of the Lesser Antilles. Steady strengthening and organization took place initially, until favorable conditions enabled it to undergo explosive intensification on the afternoon of September 18, achieving Category 5 strength just before making landfall on the island of Dominica that night. After crossing the island and weakening slightly, Maria re-intensified and achieved its peak intensity with maximum sustained winds of 175 mph (280 km/h) and a pressure of 908 mbar (hPa; 26.81 inHg). On September 20, an eyewall replacement cycle weakened Maria to a high-end Category 4 hurricane by the time it struck Puerto Rico. The hurricane re-emerged weaker from land interaction, but quickly restrengthened back into a major hurricane again the following day. Passing north of The Bahamas, Maria remained a powerful hurricane over the following week as it slowly paralleled the East Coast of the United States, gradually weakening over time as conditions became less favorable. Maria then stalled and swung eastward over the open Atlantic, becoming extratropical on September 30 before dissipating by October 2. Maria brought catastrophic devastation to the entirety of Dominica, destroying housing stock and infrastructure beyond repair, and practically eradicating the island's lush vegetation. The neighboring islands of Guadeloupe and Martinique endured widespread flooding, damaged roofs, and uprooted trees. Puerto Rico suffered catastrophic damage and a major humanitarian crisis; most of the island's population suffered from flooding and a lack of resources, compounded by a slow relief process. The storm caused the worst electrical blackout in US history, which persisted for several months. Maria also landed in the northeast Caribbean during relief efforts from another Category 5 hurricane, Irma, which crossed the region two weeks prior. The total death toll is 3,059: an estimated 2,975 in Puerto Rico, 65 in Dominica, 5 in the Dominican Republic, 4 in Guadeloupe, 4 in the contiguous United States, 3 in the United States Virgin Islands, and 3 in Haiti. Maria was the deadliest hurricane in Dominica since the 1834 Padre Ruíz hurricane and the deadliest in Puerto Rico since the 1899 San Ciriaco hurricane. This makes it the deadliest named Atlantic hurricane of the 21st century to date. The name Maria was later retired following the 2017 season.

Hurricane Maria, immensely powerful and destructive tropical cyclone that ravaged the island country of Dominica and severely devastated the U.S. territory of Puerto Rico in late September 2017. Hurricane Maria’s accompanying wind gusts, excessive rainfall, storm surges, and waves also inflicted serious damage on islands in Guadeloupe and the U.S. Virgin Islands. Hurricane Maria is the second deadliest hurricane in U.S. history, with an official estimated death toll of 2,975 people in Puerto [...] Hurricane Maria began as a well-defined tropical wave off the west coast of Africa near the Cape Verde islands on September 12, 2017. The system quickly moved over the tropical Atlantic for three days, and by the morning of September 16, it formed a tropical depression approximately 580 nautical miles (1,070 km) east of Barbados. The depression became Tropical Storm Maria just a few hours later. On September 17 the storm intensified and became Hurricane Maria at 5:00 pm local time. With ideal [...] Hurricane Maria began near the Cape Verde islands, formed a tropical depression on September 16, 2017, became a hurricane on September 17, and made landfall in Dominica on September 18.

On the morning of Wednesday, September 20, 2017, Hurricane Maria struck Puerto Rico with sustained winds of 155 mph, uprooting trees, downing weather stations and cell towers, and ripping wooden and tin roofs off homes. Electricity was cut off to 100 percent of the island, and access to clean water and food became limited for most. The powerful Category 4 storm devastated the island and plunged all of its 3.4 million residents into a desperate humanitarian crisis. [...] The effects of the hurricane — the worst storm to strike the island in over 80 years — caused as much as $94.4 billion in damages. About 80 percent of the island’s crop value was wiped out by Maria, representing a $780 million loss in agricultural yields — a devastating blow to an island with high poverty and already-fragile food security. [...] Many young people depend on the resources they find at school to help them overcome crisis-induced stress, but Hurricane Maria disrupted the lives of some 350,000 public school students. It took nearly five weeks before the first public schools began to reopen after the storm, though most were still operating without power.

Hurricane María made landfall in Puerto Rico on September 20, 2017. The storm had already caused widespread destruction in Dominica as a Category 5 storm, and it alternated between Category 4 and 5 as it approached Puerto Rico. With a minimum pressure of 908 hPa, Maria was the tenth most intense Atlantic hurricane on record. [...] As the eye of the storm tracked toward the west-northwest over Puerto Rico, the intense winds broke and uprooted trees, leaving most of those still standing without any leaves. It severely damaged 95 percent of cell towers, cutting off nearly all cell phone communication. María destroyed what was still functioning in Puerto Rico's electrical grid after Irma, leaving all residents across the island completely without power. [...] Hurricane María's damage has been severe and lasting. The storm caused structural damage to an unknown number of buildings and destroyed nearly all road signs and traffic lights. It wiped out roads, leaving less than 8 percent of them open a month after the hurricane. Five months after the storm, a quarter of the island's residents still lacked electricity.

Hurricane Maria made landfall in Puerto Rico on Wednesday, September 20. Sustained winds of 64 mph (103 km/h), with gusts up to 113 mph (182 km/h), were reported in the capital city of San Juan shortly before landfall. After landfall, gusts of 109 mph (175 km/h) were reported at Yabucoa Harbor, and gusts of 118 mph (190 km/h) at Camp Santiago. A minimum barometric pressure reading of 926.6 mbar (27.36 inHg) was reported in Yabucoa. In addition, very heavy rainfall occurred throughout the [...] 155 mph (249 km/h) and a central pressure of 920 mbar (27 inHg). It was the second-strongest recorded hurricane to hit the island, surpassed only by the 1928 San Felipe Segundo hurricane, which is the only Category 5 hurricane to have ever struck Puerto Rico. [...] Maria first developed into a tropical depression on September 16 while it was located about 665 miles (1,070 km) east of Barbados. Conditions favorable for hurricane activity allowed the storm to strengthen throughout the day, and a convective burst over the center propelled Maria to hurricane strength late on September 17. Over the next 24 hours, Maria explosively strengthened to Category 5 status just 15 miles (24 km) east-southeast of Dominica, before making landfall on that island early on
