Question: What was the hurricane that hit the country where the immigration led to?

full_context: Document 1: History of Puerto Rico: Located in the northeastern Caribbean, Puerto Rico formed a key part of the Spanish Empire from the early years of the exploration, conquest and colonization of the New World. The island was a major military post during many wars between Spain and other European powers for control of the region in the 16th, 17th and 18th centuries. The smallest of the Greater Antilles, Puerto Rico was a stepping - stone in the passage from Europe to Cuba, Mexico, Central America, and the northern territories of South America. Throughout most of the 19th century until the conclusion of the Spanish -- American War, Puerto Rico and Cuba were the last two Spanish colonies in the New World; they served as Spain's final outposts in a strategy to regain control of the American continents. Realizing that it was in danger of losing its two remaining Caribbean territories, the Spanish Crown revived the Royal Decree of Graces of 1815. The decree was printed in Spanish, English and French in order to attract Europeans, with the hope that the independence movements would lose their popularity and strength with the arrival of new settlers. Free land was offered to those who wanted to populate the islands on the condition that they swear their loyalty to the Spanish Crown and allegiance to the Roman Catholic Church.
Document 2: Hurricane Maria: Hurricane Maria was regarded as the worst natural disaster on record in Dominica and Puerto Rico, and caused catastrophic damage and triggered a major humanitarian crisis in the latter. The tenth-most intense Atlantic hurricane on record and the most intense tropical cyclone worldwide thus far 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 just two weeks prior. Maria was the third consecutive major hurricane to threaten the Leeward Islands in two weeks, after Irma made landfall in several of the islands two weeks prior and Hurricane Jose passed dangerously close, bringing tropical storm force winds to Barbuda.
Document 3: Puerto Rico: Originally populated by the indigenous Taíno people, the island was claimed in 1493 by Christopher Columbus for Spain during his second voyage. Later it endured invasion attempts from the French, Dutch, and British. Four centuries of Spanish colonial government influenced the island's cultural landscapes with waves of African slaves, Canarian, and Andalusian settlers. In the Spanish Empire, Puerto Rico played a secondary, but strategic role when compared to wealthier colonies like Peru and the mainland parts of New Spain. Spain's distant administrative control continued up to the end of the 19th century, helping to produce a distinctive creole Hispanic culture and language that combined elements from the Native Americans, Africans, and Iberians. In 1898, following the Spanish -- American War, the United States acquired Puerto Rico under the terms of the Treaty of Paris. The treaty took effect on April 11, 1899.

Document 5: Puerto Rico: Originally populated by the indigenous Taíno people, the island was claimed in 1493 by Christopher Columbus for the Crown of Castile during his second voyage. Later it endured invasion attempts from the French, Dutch, and British. Four centuries of Spanish colonial government transformed the island's ethnic, cultural and physical landscapes primarily with waves of African slaves, and Canarian, and Andalusian settlers. In the Spanish imperial imagination, Puerto Rico played a secondary, but strategic role when compared to wealthier colonies like Peru and the mainland parts of New Spain. Spain's distant administrative control continued up to the end of the 19th century, helping to produce a distinctive creole Hispanic culture and language that combined elements from the Native Americans, Africans, and Iberians. In 1898, following the Spanish -- American War, the United States acquired Puerto Rico along with other Spanish colonies under the terms of the Treaty of Paris.
Document 6: Hurricane Harvey: Hurricane Harvey Category 4 major hurricane (SSHWS / NWS) Hurricane Harvey at peak intensity, prior to landfall in southern Texas on August 25 Formed August 17, 2017 (2017 - 08 - 17) Dissipated September 3, 2017 (2017 - 09 - 03) (Extratropical after September 1) Highest winds 1 - minute sustained: 130 mph (215 km / h) Lowest pressure 938 mbar (hPa); 27.7 inHg Fatalities 63 direct, 27 indirect Damage ≥ $70 billion (2017 USD) (Preliminary total; unofficially third - costliest tropical cyclone in U.S. history) Areas affected Windward Islands, Suriname, Guyana, Nicaragua, Honduras, Belize, Cayman Islands, Yucatán Peninsula, Southern and Eastern United States (especially Texas, Louisiana) Part of the 2017 Atlantic hurricane season
Document 7: Hurricane Irma: Hurricane Irma was an extremely powerful and catastrophic Cape Verde - type hurricane, the strongest observed in the Atlantic in terms of maximum sustained winds since Wilma and the strongest storm on record to exist in the open Atlantic region. It was the first Category 5 hurricane to strike the Leeward Islands on record, followed by Hurricane Maria two weeks later, and is the second - costliest Caribbean hurricane on record, after Maria. The ninth named storm, fourth hurricane, second major hurricane, and first Category 5 hurricane of the 2017 Atlantic hurricane season, Irma caused widespread and catastrophic damage throughout its long lifetime, particularly in parts of the northeastern Caribbean and the Florida Keys. It was also the most intense Atlantic hurricane to strike the continental United States since Katrina in 2005, the first major hurricane to make landfall in Florida since Wilma in the same year and the first category 4 hurricane to landfall in the state since Charley in 2004.
Document 8: Hurricane Maria: 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.

Document 13: Independence movement in Puerto Rico: After four hundred years of colonial rule by the Spanish Empire, Puerto Rico finally received its sovereignty in 1897 through a Carta de Autonomía (Charter of Autonomy). It was signed by Spanish Prime Minister Práxedes Mateo Sagasta and ratified by the Spanish Cortes.
Document 14: Currencies of Puerto Rico: The situado was discontinued during the 19th century, creating an economic crisis, as a result of Mexico gaining its independence from Spain. Salvador Meléndez Bruna, the colonial governor in office, ordered the issue of provincial banknotes, creating the Puerto Rican peso. However, printing of these banknotes ceased after 1815. During the following decades, foreign coins became the widespread currency. In the 1860s and 1870s, banknotes reemerged. On February 1, 1890, the Banco Español de Puerto Rico was inaugurated and began issuing banknotes. The bank designed four series and placed three in circulation under Spanish rule. In 1895, a Royal Decree ordered the production of provincial peso coins.
Document 15: History of Puerto Rico: On August 10, 1815, the Royal Decree of Grace was issued, allowing foreigners to enter Puerto Rico (including French refugees from Hispaniola), and opening the port to trade with nations other than Spain. This was the beginning of agriculture-based economic growth, with sugar, tobacco, and coffee being the main products. The Decree also gave free land to anyone who swore their loyalty to the Spanish Crown and their allegiance to the Roman Catholic Church. Thousands of families from all regions of Spain (particularly Asturias, Catalonia, Majorca and Galicia), Germany, Corsica, Ireland, France, Portugal, the Canary Islands and other locations, escaping from harsh economic times in Europe and lured by the offer of free land, soon immigrated to Puerto Rico. However, these small gains in autonomy and rights were short lived. After the fall of Napoleon, absolute power returned to Spain, which revoked the Cádiz Constitution and reinstated Puerto Rico to its former condition as a colony, subject to the unrestricted power of the Spanish monarch.
