tropical cyclones

The swell from Evan was a true cyclone swell, one that was generated in the core of a severe, slow moving tropical cyclone, and yet it was nothing like a classic cyclone swell. The reason Evan won't be remembered that way is because it formed in isolation. Despite spending a week in the far reaches of our swell window and wreaking havoc on Samoa and Fiji, Evan lacked the associated weather features required to create classic cyclone swell conditions.
