For the full season that began June 1, 17 named storms formed.
Forecasters warned that this hurricane season would be more active than normal, and they were right. As we previously reported, the National Hurricane Center produced its most accurate forecasts on record - when it mattered so much. "It wasn't just that the longer-range forecasts were good, they were all good".
While this year's season was above average, it was not a record breaker.
Harvey, which made landfall in Texas and caused devastating flood damage near Houston, finally began moving northward after stalling in the Lone Star State for almost a week.
- Strongest winds were clocked at 185 miles per hour, the second strongest hurricane in the Atlantic Basin in history. Early damage estimates exceed $300 billion with hundreds of people killed along their catastrophic paths. There were more than the usual number of storms this hurricane season with 17 named storms, 10 hurricanes and six major (category 3 or stronger) hurricanes.
Category 4 Harvey, the first major hurricane to hit the USA mainland since 2004, set a new US record for rainfall (60.5 inches near Nederland, Texas), the Miami Herald reported.
A lake is hit by Hurricane Irma in Pembroke Pines, Florida on Sunday.
Irma will be most remembered for its disgusting toll in the Caribbean, utterly destroying the island of Barbuda, shredding sections of the Virgin Islands and then knocking out power to much of Florida. That extreme activity also followed a four-year string of Septembers from 2013 to 2016 that Klotzbach called the "quietest" four Septembers since the period between 1911 and 1914.
Thursday marks the last day of the busiest Atlantic hurricane season in years.
Since Hurricane Maria struck Puerto Rico in mid-September, the island has struggled to restore water and power. Nate became the fastest moving hurricane over the Gulf of Mexico, before smashing into the mouth of the Mississippi River. It became the easternmost Atlantic major hurricane on record.
Maria was the strongest hurricane to make landfall in Puerto Rico since 1928. Toward the end of the season, Ophelia smacked Ireland with 119 miles per hour winds.
