What is the official designation for Invests in that region? They might need to add one. So if this becomes a TC, it is NHC responsibility?

Presumably P, as with all other South Pacific invests.

This area is covered by the NWS yes. Quite fittingly re the P this is just off the coast of Peru.

Never got above T1.0 so no TD.

I wonder if there has ever been a TC in the SE Pacific?

Technically, if you define the SE Pacific as the South Pacific Ocean east of the dateline, there is a storm there right now (Jasmine). If you define it as east of 140ºW (the NHC territory), that is much more rare. Cyclone Ursula in 1998, for example, reached 125ºW before becoming extratropical, although Wellington tracked it to 110ºE. According to the International Best track - http://storm5.atms.unca.edu/browse-ibtracs/browseIbtracs.php?name=browse-location - Ursula was the easternmost storm in the South Pacific. So, if this storm had developed, it would certainly be an anomaly.

[P.K.]

Nice find that site. I'd define SE as being east of 120W given that is how far MetArea XIV extends.

[Reesie]

If this analysis from the University of Hawaii's is acceptable, the eastern most TC in the SPAC developed at around 110W.
