After a long lull in major hurricanes striking the U.S. (2005 - 2017), the 2017 season was an extremely destructive season, featuring 17 named storms in just the Atlantic Ocean, tying it with 1936 as the fifth-most active season since records began in 1851. All ten of the Atlantic hurricanes occurred in a row, the greatest number of consecutive hurricanes in the satellite era. In addition, it is by far the costliest season on record, with a preliminary total of over $368.66 billion (USD) in damages, which is more than double the cost of 2005’s total, and nearly all of which was due to three of the season's major hurricanes — Harvey, Irma, and Maria. All three occurred within one month in August - September, sending disaster aide efforts reeling and calling on volunteers for help.
Hurricane Maria, is regarded as the worst natural disaster on record in Dominica and Puerto Rico, while also being the most intense tropical cyclone worldwide in 2017, it was a true catastrophe for the people and infrastructure for several Caribbean islands. For example, Maria effectively destroyed Puerto Rico's power grid. Three months after the hurricane, 45% of Puerto Ricans were still without power. It followed directly behind Hurricane Irma , the strongest tropical storm ever observed in terms of wind speed with 36 hours of sustained category 5 185 mph winds, struck the Florida Keys and Florida's Gulf Coast.
