While these seasonal outlooks are interesting and may give us some perspective to the upcoming hurricane season, it's important to remember that location is more important than numbers. A season with low numbers but multiple local impacts is "more active" than a season with high numbers but no local impacts. One landfall has much more weight than a dozen "fish storms"
The Atlantic hurricane season starts on June 1st and ends on November 30th, but storms can (and have) formed outside of the official season dates.
