The tenth-most intense Atlantic hurricane on record and 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 the deadliest storm of the hyperactive 2017 Atlantic hurricane season . At its peak, the hurricane caused catastrophic damage and numerous fatalities across the northeastern Caribbean, compounding recovery efforts in the areas of the Leeward Islands already struck by Hurricane Irma . Total losses from the hurricane are estimated at upwards of $91.61 billion (2017 USD), mostly in Puerto Rico, ranking it as the third - costliest tropical cyclone on record . </P> <P> Originating from a tropical wave, Maria became a tropical storm on September 16, east of the Lesser Antilles . Highly favorable environmental conditions allowed the storm to undergo explosive intensification as it approached the island arc . The hurricane reached Category 5 strength on September 18 just before making landfall on Dominica, becoming the first Category 5 hurricane on record to strike the island . After weakening slightly due to crossing Dominica, Maria achieved its peak intensity over the eastern Caribbean with maximum sustained winds of 175 mph (280 km / h) and a pressure of 908 mbar (hPa; 26.81 inHg), making it the tenth-most intense Atlantic hurricane on record . On September 20, an eyewall replacement cycle took place, weakening Maria to a high - end Category 4 hurricane by the time it struck Puerto Rico . Interaction with land further weakened the hurricane, though it regained some strength as it moved northeast of The Bahamas . Moving slowly to the north, Maria gradually degraded and weakened to a tropical storm on September 28 . Embedded in the westerlies, Maria accelerated toward the east and later east - northeast over the open Atlantic, becoming extratropical on September 30 and dissipating by October 3 . </P>
