The major factors expected to produce the high level of tropical activity are:
- Favorable upper level winds: Wind shear (change in wind with height) is expected to be low since the El Niño conditions in the equatorial Pacific have dissipated.
- Warm sea surface temperatures: Atlantic Ocean temperatures are at record high levels, as much as 4° above average.
- Continuing high activity era: Eight of the 15 seasons since 1995 are in the top 10 list for named storms.
