Why the 2018 Hurricane Season Was More Active Than We Predicted

At a Glance

  • More storms and hurricanes formed this season than were expected.
  • We talked to a couple of the seasonal outlook experts to see what happened.
  • Michael and Florence led to billions of dollars in damage and many broken records.
The 2018 Atlantic hurricane season included two billion-dollar hurricanes and a slightly above-average number of named storms, which overshot seasonal forecasts.
In our end-of-season recap, we spoke to a few of the experts who issue seasonal forecasts to learn why the year was more active than expected.


75 mph to 130 mph in just 25 hours, ending at noon EDT Sept. 10.
Florence made landfall near Wrightsville Beach, North Carolina, at 7:15 a.m. EDT Sept. 14 with maximum sustained winds around 90 mph.
Florence's water was a major story days before it slowed down and made landfall. Surf came up on the shores of North Carolina as Florence passed south of Bermuda, then flooded the town of New Bern in the eastern part of the Tar Heel State with more than 10 feet of storm surge.
Then rainfall became a big story as Florence drifted inland.
