I do not see much, if any, organization from this system at all

[cycloneye]

I am not very familiar with the Central Pacific so here is my question.What is the average of named storms in that basin? I can guess is the lowest in the world.

[RL3AO]

This decade has had 5 named storms in the CPac with three of them being in 2002.

This decade has had 5 named storms in the CPac with three of them being in 2002.

That is superslow.

I am not very familiar with the Central Pacific so here is my question.What is the average of named storms in that basin? I can guess is the lowest in the world.

Using a climo set of 30 years...

In that period of time, the CPAC has had 28 tropical storms, 15 hurricanes, 10 major hurricanes, and 4 category five hurricanes.

That yields an average of 0.93, 0.5, 0.33, and 0.13, respectively.

(This does include systems that formed in the CPAC, but later intensified in the WPAC.)

Iniki was an EPac TD that didn't get upgraded to a named storm until it crossed 140ºW, hence the Hawai'ian name. If it had been named a few hours earlier, it would most likely have had a Hispanic name.

Iniki was an EPac TD that didn't get upgraded to a named storm until it crossed 140ºW, hence the Hawai'ian name. If it had been named a few hours earlier, it would most likely have had a Hispanic name.

It would have been named Paine.

Another fun fact--

1992 was the year the EPAC reached the name Zeke. Had Iniki been named E of 140°W, thus being name Paine, the storm that became Tropical Storm Zeke would have been named Tropical Storm Alpha... marking the first time the EPAC used the Greek Alphabet with the main list exhausted.

Similar to 2005 when you had the unnamed storm in the Atlantic. If that would have been named, then Wilma would have been Alpha. That would have caused an interesting retirement scenario.
