The season officially began on June 1 and will end on November 30. These dates historically describe the period of year when most tropical cyclones form in the Atlantic basin and are adopted by convention. However, as shown by Tropical Storm Arlene in April, the formation of tropical cyclones is possible at other times of the year. Arlene made 2017 the third consecutive year to feature a pre-season storm. In mid-June, Tropical Storm Bret struck the island of Trinidad, which is only rarely struck by tropical cyclones due to its low latitude. A few days later, Tropical Storm Cindy struck the state of Louisiana. In late August, Hurricane Harvey became the first major hurricane to make landfall in the United States since Wilma in 2005, while also setting the record for the costliest tropical cyclone on record, as well as the most rainfall dropped by a tropical cyclone in the US. In early September, Hurricane Irma, a Cape Verde - type hurricane, became the first Category 5 hurricane to impact the northern Leeward Islands on record, and in terms of maximum sustained winds, is tied with the 1935 Labor Day hurricane as the strongest hurricane ever to make landfall in the Atlantic basin. The season also featured the fastest - moving tropical cyclone ever recorded in the Gulf of Mexico (Nate). The season also featured Ophelia, the easternmost major hurricane in the basin on record, which later impacted most of Northern Europe while extratropical.
