It’s ten days until the end of the Atlantic hurricane season, and as I write this, named storm #19, Sebastien, is moving through the Central Atlantic (no threat to the Southeast, happily). It’s predicted to become a hurricane on Thursday. It’s been a busy year, which was predicted by NOAA and other groups, but what factors made it so active? NOAA has a good article which describes some of the reasons at https://www.noaa.gov/stories/atlantic-high-activity-eras-what-does-it-mean-for-hurricane-season.
