The CSU team also included the probability for at least one major hurricane landfall on...

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.
