'''Hurricane Maria''' was a [[Saffir-Simpson Hurricane Scale#Category 1|Category 1 hurricane]] that [[Landfall (meteorology)|came ashore]] the island of [[Newfoundland (island)|Newfoundland]] during September 2011. Originating from a [[tropical wave]] over the central Atlantic on September 6, Maria moved generally towards the west while slowly strengthening. However, while approaching the northern [[Leeward Islands]], the system entered a region of higher vertical [[wind shear]] and cooler [[sea surface temperatures]], subsequently degenerating into a [[Low-pressure area|low-pressure area]]. Executing a C-shaped track around the western periphery of the [[Subtropical ridge|subtropical ridge]], Maria regained tropical storm status on September 10, and further strengthened to attain hurricane status while making its closest approach to [[Bermuda]]. The cyclone attained peak winds of 80 mph (130 km/h) on September 16, but weakened thereafter due to an increase in vertical wind shear and cooler sea surface temperatures. Maria made landfall on the southeastern coast of Newfoundland during the afternoon hours of September 16 before becoming absorbed by a [[Weather front|frontal system]] late on that same day. |
|||
Despite its poor organization, Maria brought heavy rainfall to portions of the east [[Caribbean]], notably [[Puerto Rico]]. Numerous roadways were flooded, and many homes were flooded. As the storm passed through the extreme northeastern Caribbean, over 15,000 people went without power. In addition, tropical storm-force winds were observed on many of the [[U.S. Virgin Islands]]. As the system passed west of Bermuda, brief tropical storm-force sustained winds were recorded, along with higher gusts; rainfall on the island, however, was minimal. In Newfoundland, strong winds were recorded, but rainfall totals were relatively minimal. There were no deaths reported in association with Maria. |

In preparation for Maria, tropical storm watches were issued for most of the [[Lesser Antilles]] on September 8. By 2230 UTC on that same day, the watches were upgraded to tropical storm warnings in the fear that tropical storm-force winds would be observed across the islands. Early the following day, [[Puerto Rico]] and many of the [[U.S. Virgin Islands]] and [[British Virgin Islands]] were placed under a tropical storm watch. However, by 1500 UTC on September 10, all tropical cyclone watches and warnings were discounted due to the fact that all deep thunderstorm activity was well removed from the circulation center. In Puerto Rico, several streets and homes were flooded due to the heavy rainfall. A total of {{convert|11.04|in|cm|abbr=on}} was recorded in Ybucoa, Puerto Rico, the highest total observed on the island. U.S. President [[Barack Obama]] declared the island a federal disaster area about a month after the storm occurred, which allocated federal assistance available for residents in three municipalities.<ref>{{cite web|publisher=Federal Emergency Management Agency|date=October 18, 2011|url=http://www.fema.gov/news/newsrelease.fema?id=58854|title=President Declares A Major Disaster For Puerto Rico|accessdate=2011-10-31}}</ref> In addition, heavy rainfall also caused landslides across the U.S. and British Virgin Islands.<ref name="telemundo">{{cite web|title=Inundaciones y carreteras afectadas por intensas lluvias|url=http://www.telemundopr.com/noticia-inundacionesycarreterasafectadasporintensaslluvias-129223.html|date=September 13, 2011|publisher=[[Telemundo]] (in Spanish)|accessdate=September 13, 2011}}</ref> |

Hurricane Maria was a Category 1 hurricane that came ashore the island of Newfoundland during September 2011. Originating from a tropical wave over the central Atlantic on September 6, Maria moved generally towards the west while slowly strengthening. However, while approaching the northern Leeward Islands, the system entered a region of higher vertical wind shear and cooler sea surface temperatures, subsequently degenerating into a low-pressure area. Executing a C-shaped track around the western periphery of the subtropical ridge, Maria regained tropical storm status on September 10, and further strengthened to attain hurricane status while making its closest approach to Bermuda. The cyclone attained peak winds of 80 mph (130 km/h) on September 16, but weakened thereafter due to an increase in vertical wind shear and cooler sea surface temperatures. Maria made landfall on the southeastern coast of Newfoundland during the afternoon hours of September 16 before becoming absorbed by a frontal system late on that same day.
Despite its poor organization, Maria brought heavy rainfall to portions of the east Caribbean, notably Puerto Rico. Numerous roadways were flooded, and many homes were flooded. As the storm passed through the extreme northeastern Caribbean, over 15,000 people went without power. In addition, tropical storm-force winds were observed on many of the U.S. Virgin Islands. As the system passed west of Bermuda, brief tropical storm-force sustained winds were recorded, along with higher gusts; rainfall on the island, however, was minimal. In Newfoundland, strong winds were recorded, but rainfall totals were relatively minimal. There were no deaths reported in association with Maria.

Unknown
Extratropical cyclone, remnant low, tropical disturbance, or monsoon depressionThe origins of Hurricane Maria can be traced back to a tropical wave—or an elongated area of low pressure oriented north to south—that moved through Nigeria and Mali on September 1. It reached the coastal country of Senegal late during the day, and began moving into the eastern tropical Atlantic early the following day. The wave slowly intensified over the subsequent days while moving generally towards the west. On September 6, it had developed a sufficient amount of convection to be designated as a tropical depression, and was classified as Tropical Depression Fourteen while situated about 700 mi (1100 km) west-southwest of the southern Cape Verde Islands.[1] By this time, it had also developed well-established outflow within the western semicircle of the low-pressure center.[2] Continuing to increase in strength, the depression was upgraded to a tropical storm six hours after formation, subsequently receiving the name Maria.[1][3]
Early on September 7, the National Hurricane Center (NHC) noted that although Maria was in an area which permitted significant strengthening, most forecasts given by intensity guidance models did not anticipate that.[4] The system changed little in organization over the 24 hours that followed as it moved rapidly towards the west-northwest around the southern periphery of the subtropical ridge. Visible satellite imagery depicted the appearance of a well-organized circulation center, but it was actually exposed on the southwest edge of the convection due to increased vertical wind shear.[5] The system reached an initial peak intensity with maximum sustained winds of 50 mph (85 km/h) on September 8 before the unfavorable environment began to penetrate the system's organization. Following a reconnaissance flight into the system early on September 9, it was noted that Maria had degenerated into a non-tropical disturbance, despite reports of tropical storm-force winds in the northern Leeward Islands;[1] however, operationally the system remained a tropical cyclone and was never downgraded to a remnant cyclone. While approaching the northern Leeward Islands on September 10, satellite imagery and surface observations revealed an increase in organization, and a subsequent reconnaissance aircraft into the disturbance revealed that the remnants of Maria had regenerated into a tropical cyclone, while located approximately 40 mi (65 km) east-southeast of Antigua.[1]
Reaching the southwestern periphery of the subtropical ridge, Maria subsequently turned to the north as its forward motion slowed considerably. Strong vertical wind shear impacting the system began to relax by September 14, and the cyclone began to slowly strengthen as convection redeveloped near Maria's center of circulation.[6] At 1800 UTC on September 15, Maria reached Category 1 status on the Saffir–Simpson Hurricane Scale while located roughly 135 mi (215 km) northwest of Bermuda.[1] Becoming embedded within the mid-latitude flow[clarification needed], the hurricane's forward motion accelerated towards the northeast. At 0000 UTC on September 16, Maria attained its peak intensity with winds of 80 mph (130 km/h) and a minimum barometric pressure of 983 mbar (29.03 inHg). Continuing on a northeastward course, Maria began to move over an area with cooler sea surface temperatures and higher vertical wind shear. By 1800 UTC, Maria had weakened to a tropical storm, and made landfall near Cape St. Mary's, Newfoundland at 1830 UTC with winds of 70 mph (110 km/h). Shortly thereafter, the cyclone's circulation was absorbed by a frontal system over the Avalon Peninsula of Newfoundland.[1]
Preparations and impact
Caribbean
In preparation for Maria, tropical storm watches were issued for most of the Lesser Antilles on September 8. By 2230 UTC on that same day, the watches were upgraded to tropical storm warnings in the fear that tropical storm-force winds would be observed across the islands. Early the following day, Puerto Rico and many of the U.S. Virgin Islands and British Virgin Islands were placed under a tropical storm watch. However, by 1500 UTC on September 10, all tropical cyclone watches and warnings were discounted due to the fact that all deep thunderstorm activity was well removed from the circulation center. In Puerto Rico, several streets and homes were flooded due to the heavy rainfall. A total of 11.04 in (28.0 cm) was recorded in Ybucoa, Puerto Rico, the highest total observed on the island. U.S. President Barack Obama declared the island a federal disaster area about a month after the storm occurred, which allocated federal assistance available for residents in three municipalities.[7] In addition, heavy rainfall also caused landslides across the U.S. and British Virgin Islands.[8]
Bermuda
Following Maria's regeneration into a tropical cyclone, a Tropical Storm Watch was issued for the island of Bermuda on September 13; this watch was upgraded to a warning later that same day. At 1200 UTC the following day, a Hurricane Watch was issued in the fear that Maria would pass close enough to the island to produce hurricane conditions. By late on September 15, all tropical cyclone watches and warnings on the island were discontinued. As Maria bypassed Bermuda on September 15, the outer bands of the storm produced brief tropical storm-force winds.[9] At Commissioners Point, sustained winds reached 52 mph (83 km/h), with gusts as high as 69 mph (111 km/h) was observed.[10] In addition, winds of 36 mph (60 km/h) were reported at L.F. Wade International Airport at 1500 UTC on September 15.[9]
Newfoundland and Labrador
In anticipation of Maria, Environment Canada issued a Tropical Storm Watch for the coast of Newfoundland, stretching from Arnolds Cove to Brigus South late on September 15; three hours later, a Hurricane Watch was issued for the same areas. Simultaneously, a Tropical Storm Warning was issued from Arnolds Cove to Jones Harbor. At 0600 UTC the following day, the Hurricane Watch and Tropical Storm Warning was changed to a Hurricane Warning. At this time, a Tropical Storm Warning was issued from Brigus South to Charlottestown, Newfoundland; all tropical cyclone watches and warnings were discontinued at 2100 UTC. As Maria was becoming absorbed by a weather front on September 16, landfall was reported on the southern tip of the Avalon Peninsula of Newfoundland where winds of 64 mph (103 km/h) were recorded. Offshore winds of 77 mph (124 km/h) were measured, and the capital city of St. John's experienced heavy rain, but not to the extent anticipated as the storm moved through more quickly than predicted.[11]
