Monday was the last “official” day of the Atlantic hurricane season, drawing down the curtain on what has been a frenetic year for storms forming in the Atlantic Ocean, Gulf of Mexico, and Caribbean Sea.

The top-line numbers are staggering: there were a total of 30 tropical storms and hurricanes, surpassing the previous record of 28 set in the year 2005. For only the second time, forecasters at the National Hurricane Center in Miami ran out of names and had to resort to using the Greek alphabet.

Of all those storms, 12 made landfall in the United States, obliterating the previous record of nine landfalling tropical storms or hurricanes set in 1916. The state of Louisiana, alone, experienced five landfalls. At least part of the state fell under coastal watches or warnings for tropical activity for a total of 474 hours this summer and fall. And Laura became the strongest hurricane to make landfall in the Pelican State since 1856.
